(8) In further describing the various aspects of the invention, the function and structure of various TERT expression enhancing compounds are described first in greater detail, followed by a description of methods and applications in which the compounds finds use.

(9) TERT Expression Enhancing Compounds

(10) As summarized above, aspects of the invention include TERT expression enhancing compounds. The TERT expression enhancing compounds are compounds that increase TERT expression in a cell upon contact with a cell or components thereof. In some instances, the types of cells in which the compounds of the invention exhibit activity are ones that include a TERT gene containing a Site C site in its promoter region, e.g., in the TERT gene minimal promoter. By increasing TERT expression is meant that the expression level of the TERT encoding mRNA is increased by 2-fold or more, such as by 5-fold or more and sometimes by 25-, 50-, or 100-fold or more and in certain embodiments 300-fold or more or higher, as compared to a control, i.e., expression in a comparable cell (such as a clone, cell from the same tissue, etc.) not contacted with the compound of interest (e.g., by using the assay described in Published United States Patent Application Publication No. US-2006-0199171-A1, the disclosure of which assay is herein incorporated by reference). Alternatively, in cases where expression of the TERT gene in a cell is so low that it is undetectable, the expression level of the TERT encoding mRNA is considered to be increased if expression is increased to a level that is easily detectable, e.g., by using the assay described in Published United States Patent Application Publication No. US-2006-0199171-A1, the disclosure of which assay is herein incorporated by reference.

(11) In certain embodiments, the target cell in which TERT expression is increased is a normal cell, e.g., a somatic cell. In some of these embodiments, the compounds of the invention are used to increase the proliferative capacity of a cell. The term proliferative capacity as used herein refers to the number of divisions that a cell can undergo, and in some instances to the ability of the target cell to continue to divide where the daughter cells of such divisions are not transformed, i.e., they maintain normal response to growth and cell cycle regulation. As such, the compounds of the invention may find use in the delay of the occurrence of cellular senescence, among other applications. The compounds of the invention may delay the onset of cellular senescence by a factor of 1.2 or more, such as 2-fold or more, including 5-fold or more where in certain embodiments the delay is even greater, e.g., 10-, 20-, 50-fold or more or even higher, compared to a control.

(12) In certain embodiments, the compounds of the invention modulate the interaction of a transcriptional repressor complex and a Site C site in the TERT promoter. By transcriptional repressor complex is meant a complex containing at least one factor (e.g., protein), wherein the complex binds specifically to a Site C site in the TERT promoter. For example, the transcriptional repressor complex can be a single protein that binds specifically to the Site C site in the TERT promoter (or minimal promoter). In contrast, the transcriptional repressor complex can contain a number of factors (e.g., proteins) that together bind specifically to the Site C site in the TERT promoter. In general, binding of the transcriptional repressor complex to a Site C site in the TERT promoter represses or reduces transcription of the TERT gene.

(13) In certain embodiments, modulating the interaction of a transcriptional repressor complex and a Site C site means that the interaction is inhibited or reduced. In certain of these embodiments, the mechanism of activity of the compounds is by specific, direct interaction with the transcriptional repressor protein complex thereby preventing its binding to Site C in the TERT promoter. In certain embodiments, the binding of the compound to the transcriptional repressor complex competitively inhibits Site C DNA binding (meaning that the compound binds to the DNA-binding site of the transcriptional repressor complex) while in other embodiments the compound allosterically inhibits Site C DNA binding of the transcriptional repressor (meaning that it binds to a site other than to the DNA binding site of the transcriptional repressor). In certain embodiments, the compound binds to a member of the transcriptional repressor complex other than the DNA binding subunit to exert its inhibitory activity.

(14) In certain embodiments, the compounds of the present invention reduce the repressive activity of a TERT transcriptional repressor complex of one or more factors (e.g., proteins), e.g., by inhibiting the binding of a transcriptional repressor to its cognate DNA binding site in the TERT minimal promoter. Of particular interest is the Site C DNA binding site within the 66 to 51 region of the TERT minimal promoter. This repressor site has been described in U.S. Pat. No. 6,686,159, which is incorporated herein by reference. In certain embodiments, the Site C sequence is:

(15) TABLE-US-00001 (SEQIDNO:1) GGCCCCGCCCTCTCCTCGCGGCGCGAGTTTCAGGCAGCGCT

(16) In certain embodiments, the target Site C sequence is a portion or subsequence of the above sequence, such as:

(17) TABLE-US-00002 (SEQIDNO:2) GGCGCGAGTTTCA;

(18) TABLE-US-00003 (SEQIDNO:3) CGCGAGTTTC;
or

(19) TABLE-US-00004 (SEQIDNO:4) GGCGCGAGTTTCAGGCAGCGC.

(20) Site C-binding transcriptional repressor complexes of interest include those described in U.S. patent application Ser. No. 11/088,001 filed on Mar. 22, 2005 entitled Methods and Compositions for Modulating Telomerase Reverse Transcriptase (TERT) Expression, which is incorporated by reference herein in its entirety. As described therein, transcriptional repressor complexes that bind to Site C site include any known or later discovered members of LSF family including any homolog or any protein or polypeptide with at least 50%, at least 70%, or at least 90% of its amino acids identical to a member of LSF family, especially within its functional regions, e.g., its DNA binding domain or regions involved in protein-protein interaction. In general, LSF family is a family of proteins related to mammalian transcription factor LSF. Members of LSF family usually include LBP1a, LBP1b, LBP1c, LBP1d, LBP9, LBP32v1, LBP32v2, SOMv1, SOMv2, SOMv3, and BOM. LBP1d is a splice variant of LBP1c while LBP1a is a splice variant of LBP1 b. In addition, members the LSF family also include a splice variant of LBP1c, called LBP1c2, and a variant of BOM, called BOMv2, as well as any protein or polypeptide capable of binding to or interacting with one or more members related to LSF, e.g., YY1, NF-E4, Fe65, APP-CT, NFPB, and SP1.

(21) In certain embodiments, the compounds of the invention increase the amount of telomerase expression from a level that is so low as to be undetectable to a level that is easily detectable, as determined by a quantitative RT-PCR assay, e.g., by an assay that determines the number of hTERT mRNA transcripts present in a cell after treatment with a compound of the invention, by measuring the Cycle Threshold value (C.sub.t, a measure of the number of PCR cycles that are required to amplify a target cDNA) and correlating it to the number of hTERT mRNA transcripts present. In certain embodiments, the compounds of the invention may increase the number of hTERT mRNA transcripts per cell to a detectable level of 1 or more, such as 2 or more, 3 or more, 10 or more, 25 or more, 50 or more, 100 or more, 200 or more, 300 or more, 500 or more, or even higher.

(22) In certain embodiments, the compounds of the invention have no significant effect of the viability of a cell, as determined by a cell viability assay, e.g., as determined by administering a compound of the invention to a cell and determining the number of viable cells in culture using a homogeneous method, such as the CellTiter-Glo Luminescent Cell Viability Assay (Promega Corporation, Madison, WI.). The compounds of the invention may exhibit a % cell viability, as compared to a control (e.g., a DMSO control), of 15% or more, such as 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, 100% or more, 120% or more, or even higher.

Pharmaceutical Preparations

(335) Also provided are pharmaceutical preparations. Pharmaceutical preparations are compositions that include a TERT expression enhancing compound (for example one or more TERT expression enhancing compounds, either alone or in the presence of one or more additional active agents) present in a pharmaceutically acceptable vehicle. The term pharmaceutically acceptable means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in mammals, such as humans. The term vehicle refers to a diluent, adjuvant, excipient, or carrier with which a compound of the invention is formulated for administration to a mammal. Such pharmaceutical vehicles can be liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical vehicles can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea, and the like. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents may be used. When administered to a mammal, the compounds and compositions of the invention and pharmaceutically acceptable vehicles, excipients, or diluents may be sterile. In some instances, an aqueous medium is employed as a vehicle when the compound of the invention is administered intravenously, such as water, saline solutions, and aqueous dextrose and glycerol solutions.

(336) Pharmaceutical compositions can take the form of capsules, tablets, pills, pellets, lozenges, powders, granules, syrups, elixirs, solutions, suspensions, emulsions, suppositories, or sustained-release formulations thereof, or any other form suitable for administration to a mammal. In some instances, the pharmaceutical compositions are formulated for administration in accordance with routine procedures as a pharmaceutical composition adapted for oral or intravenous administration to humans. Examples of suitable pharmaceutical vehicles and methods for formulation thereof are described in Remington: The Science and Practice of Pharmacy, Alfonso R. Gennaro ed., Mack Publishing Co. Easton, Pa., 19th ed., 1995, Chapters 86, 87, 88, 91, and 92, incorporated herein by reference.

(337) The choice of excipient will be determined in part by the particular compound, as well as by the particular method used to administer the composition. Accordingly, there is a wide variety of suitable formulations of the pharmaceutical composition of the present invention.

(338) Administration of TERT expression enhancing compounds of the invention may be systemic or local. In certain embodiments administration to a mammal will result in systemic release of a compound of the invention (for example, into the bloodstream). Methods of administration may include enteral routes, such as oral, buccal, sublingual, and rectal; topical administration, such as transdermal and intradermal; and parenteral administration. Suitable parenteral routes include injection via a hypodermic needle or catheter, for example, intravenous, intramuscular, subcutaneous, intradermal, intraperitoneal, intraarterial, intraventricular, intrathecal, and intracameral injection and non-injection routes, such as intravaginal rectal, or nasal administration. In particular embodiments, the compounds and compositions of the invention are administered orally. In particular embodiments, it may be desirable to administer one or more compounds of the invention locally to the area in need of treatment. This may be achieved, for example, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as sialastic membranes, or fibers.

(339) The TERT expression enhancing compounds can be formulated into preparations for injection by dissolving, suspending or emulsifying them in an aqueous or nonaqueous solvent, such as vegetable or other similar oils, synthetic aliphatic acid glycerides, esters of higher aliphatic acids or propylene glycol; and if desired, with conventional additives such as solubilizers, isotonic agents, suspending agents, emulsifying agents, stabilizers and preservatives.

(340) In some embodiments, formulations suitable for oral administration can include (a) liquid solutions, such as an effective amount of the compound dissolved in diluents, such as water, or saline; (b) capsules, sachets or tablets, each containing a predetermined amount of the active ingredient, as solids or granules; (c) suspensions in an appropriate liquid; and (d) suitable emulsions. Tablet forms can include one or more of lactose, mannitol, corn starch, potato starch, microcrystalline cellulose, acacia, gelatin, colloidal silicon dioxide, croscarmellose sodium, talc, magnesium stearate, stearic acid, and other excipients, colorants, diluents, buffering agents, moistening agents, preservatives, flavoring agents, and pharmacologically compatible excipients. Lozenge forms can include the active ingredient in a flavor, usually sucrose and acacia or tragacanth, as well as pastilles including the active ingredient in an inert base, such as gelatin and glycerin, or sucrose and acacia, emulsions, gels, and the like containing, in addition to the active ingredient, such excipients as are described herein.

(341) The subject formulations of the present invention can be made into aerosol formulations to be administered via inhalation. These aerosol formulations can be placed into pressurized acceptable propellants, such as dichlorodifluoromethane, propane, nitrogen, and the like. They may also be formulated as pharmaceuticals for non-pressured preparations such as for use in a nebulizer or an atomizer.

(342) In some embodiments, formulations suitable for parenteral administration include aqueous and non-aqueous, isotonic sterile injection solutions, which can contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. The formulations can be presented in unit-dose or multi-dose sealed containers, such as ampules and vials, and can be stored in a freeze-dried (lyophilized) condition requiring only the addition of the sterile liquid excipient, for example, water, for injections, immediately prior to use. Extemporaneous injection solutions and suspensions can be prepared from sterile powders, granules, and tablets of the kind previously described.

(343) Formulations suitable for topical administration may be presented as creams, gels, pastes, or foams, containing, in addition to the active ingredient, such carriers as are appropriate. In some embodiments the topical formulation contains one or more components selected from a structuring agent, a thickener or gelling agent, and an emollient or lubricant. Frequently employed structuring agents include long chain alcohols, such as stearyl alcohol, and glyceryl ethers or esters and oligo(ethylene oxide) ethers or esters thereof. Thickeners and gelling agents include, for example, polymers of acrylic or methacrylic acid and esters thereof, polyacrylamides, and naturally occurring thickeners such as agar, carrageenan, gelatin, and guar gum. Examples of emollients include triglyceride esters, fatty acid esters and amides, waxes such as beeswax, spermaceti, or carnauba wax, phospholipids such as lecithin, and sterols and fatty acid esters thereof. The topical formulations may further include other components, e.g., astringents, fragrances, pigments, skin penetration enhancing agents, sunscreens (i.e., sunblocking agents), etc.

(344) For use in wound healing or treatment of other acute or chronic conditions of the epidermis, a compound of the invention may be formulated for topical administration. The vehicle for topical application may be in one of various forms, e.g. a lotion, cream, gel, ointment, stick, spray, or paste. They may contain various types of carriers, including, but not limited to, solutions, aerosols, emulsions, gels, and liposomes. The carrier may be formulated, for example, as an emulsion, having an oil-in-water or water-in-oil base. Suitable hydrophobic (oily) components employed in emulsions include, for example, vegetable oils, animal fats and oils, synthetic hydrocarbons, and esters and alcohols thereof, including polyesters, as well as organopolysiloxane oils. Such emulsions also include an emulsifier and/or surfactant, e.g. a nonionic surfactant to disperse and suspend the discontinuous phase within the continuous phase.

(345) Suppository formulations are also provided by mixing with a variety of bases such as emulsifying bases or water-soluble bases. Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams.

(346) A compound of the invention may also be formulated as a dietary supplement or nutraceutical, e.g., for oral administration. For a nutraceutical formulation, or an oral pharmaceutical formulation, suitable excipients include pharmaceutical grades of carriers such as mannitol, lactose, glucose, sucrose, starch, cellulose, gelatin, magnesium stearate, sodium saccharine, and/or magnesium carbonate. For use in oral liquid formulations, the composition may be prepared as a solution, suspension, emulsion, or syrup, being supplied either in solid or liquid form suitable for hydration in an aqueous carrier, such as, for example, aqueous saline, aqueous dextrose, glycerol, or ethanol, preferably water or normal saline. If desired, the composition may also contain minor amounts of non-toxic auxiliary substances such as wetting agents, emulsifying agents, or buffers. A compound of the invention may also be incorporated into existing nutraceutical formulations, such as are available conventionally, which may also include an herbal extract.

(347) Unit dosage forms for oral or rectal administration such as syrups, elixirs, and suspensions may be provided wherein each dosage unit, for example, teaspoonful, tablespoonful, tablet or suppository, contains a predetermined amount of the composition containing one or more inhibitors. Similarly, unit dosage forms for injection or intravenous administration may include the inhibitor(s) in a composition as a solution in sterile water, normal saline or another pharmaceutically acceptable carrier.

(348) The term unit dosage form, as used herein, refers to physically discrete units suitable as unitary dosages for human and animal subjects, each unit containing a predetermined quantity of compounds of the present invention calculated in an amount sufficient to produce the desired effect in association with a pharmaceutically acceptable diluent, carrier or vehicle. The specifications for the novel unit dosage forms of the present invention depend on the particular compound employed and the effect to be achieved, and the pharmacodynamics associated with each compound in the host.

(349) Dose levels can vary as a function of the specific compound, the nature of the delivery vehicle, and the like. Desired dosages for a given compound are readily determinable by a variety of means.

(350) The dose administered to an animal, particularly a human, in the context of the present invention should be sufficient to effect a prophylactic or therapeutic response in the animal over a reasonable time frame, e.g., as described in greater detail below. Dosage will depend on a variety of factors including the strength of the particular compound employed, the condition of the animal, and the body weight of the animal, as well as the severity of the illness and the stage of the disease. The size of the dose will also be determined by the existence, nature, and extent of any adverse side-effects that might accompany the administration of a particular compound.

(351) In pharmaceutical dosage forms, the TERT expression enhancing compounds may be administered in the form of a free base, their pharmaceutically acceptable salts, or they may also be used alone or in appropriate association, as well as in combination, with other pharmaceutically active compounds.

METHODS OF USE

(352) Aspects of the invention further include methods of using TERT expression enhancing compounds, e.g., as described above, to enhance TERT expression in a target cell population. In practicing methods of the invention, the cells of interest are contacted with an effective amount of a TERT expression enhancing compound, e.g., as described above. By effective amount is meant an amount of the TERT expression enhancing compound that is sufficient to enhance TERT expression in the target cell population to a desired level. By enhancing TERT expression is meant that the expression level of the TERT coding sequence is increased by 2-fold or more, such as by 5-fold or more and including by 25-, 50-, 100-fold or more, such as by 300-fold or more, as compared to a control, i.e., expression from an expression system that is not subjected to the methods of the present invention. Alternatively, in cases where expression of the TERT gene is so low that it is undetectable, expression of the TERT gene is considered to be enhanced if expression is increased to a level that is easily detectable.

(353) In practicing methods of the invention, the cells of interest may be contacted with the effective amount of the TERT expression enhancing compound in an in vitro or ex vivo culture system, or in vivo. For example, a TERT expression enhancing compound may be contacted to primary cells grown under standard tissue culture conditions or alternatively to cells that are part of a whole animal (e.g., administered to a subject). As such, the target cell or collection of cells may vary, where the collection of cells may be cultured cells, a whole animal or portion thereof, e.g., tissue, organ, etc. As such, the target cell(s) may be a host animal or portion thereof, or may be a therapeutic cell (or cells) which is to be introduced into a multi-cellular organism, e.g., a cell employed in gene therapy. In such methods, an effective amount of an active agent is administered to the target cell or cells, e.g., by contacting the cells with the agent, by administering the agent to the animal, etc. By effective amount is meant a dosage sufficient to modulate TERT expression in the target cell(s), as desired.

(354) In the subject methods, the TERT expression enhancing compound may be contacted with the target cells using any convenient protocol that results in the desired enhancement of TERT expression. Thus, the TERT expression enhancing compound can be incorporated into a variety of pharmaceutical compositions for therapeutic administration, e.g., as described above. For example, the TERT expression enhancing compound can be formulated into pharmaceutical compositions by combination with appropriate, pharmaceutically acceptable carriers or diluents, and may be formulated into preparations in solid, semi-solid, liquid or gaseous forms, such as tablets, capsules, powders, granules, ointments (e.g., skin creams), solutions, suppositories, injections, inhalants and aerosols, such as described above. As such, administration of the TERT expression enhancing compounds can be achieved in various ways, including oral, buccal, rectal, parenteral, intraperitoneal, intradermal, transdermal, intracheal, etc., administration.

(355) The subject methods find use in the treatment of a variety of different conditions in which the enhancement of TERT expression in the host is desired. By treatment is meant that at least an amelioration of the symptoms associated with the condition afflicting the host is achieved, where amelioration is used in a broad sense to refer to at least a reduction in the magnitude of a parameter, e.g. symptom (such as inflammation), associated with the condition being treated. As such, treatment also includes situations where the pathological condition, or at least symptoms associated therewith, are completely inhibited, e.g., prevented from happening, or stopped, e.g. terminated, such that the host no longer suffers from the condition, or at least the symptoms that characterize the condition.

(356) A variety of hosts are treatable according to the subject methods. Generally such hosts are mammals or mammalian, where these terms are used broadly to describe organisms which are within the class mammalia, including the orders carnivore (e.g., dogs and cats), rodentia (e.g., mice, guinea pigs, and rats), and primates (e.g., humans, chimpanzees, and monkeys). In many embodiments, the hosts will be humans.

(357) Also provided are methods of screening TERT expression enhancing compounds, e.g., as described above, for their ability to inhibit binding of a transcriptional repressor protein/protein complex to a TERT promoter that includes at least one of Site C binding site. Aspects of these screening methods may include determining whether a candidate TERT expression enhancing compound is capable of inhibiting binding of the transcriptional repressor protein/protein complex to the Site C binding site. Screening methods may include screening for TERT expression enhancing activity in a cell containing a TERT expression system that includes at least one Site C binding site in its promoter. Such methods may include: (i) contacting the cell with an effective amount of a candidate TERT expression enhancing compound; and (ii) determining whether the candidate compound inhibits binding of a transcriptional repressor protein/protein complex to the Site C binding site.

(358) The determining step may be carried out by any one or more of a variety a protocols for characterizing TERT expression and/or the inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site of the TERT expression system. For example, screening may be a reconstitution assay, cell-based assay, enzyme assay, ELISA assay or other related biological assay for assessing TERT expression and/or the inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site of the TERT expression system, and the determining or assessment step suitable for application in such assays are well known and involve routine protocols. Screening may also include in silico approaches, in which one or more physical and/or chemical attributes of a compound of interest are expressed in a computer-readable format and evaluated by any one or more of a variety molecular modeling and/or analysis programs and algorithms suitable for this purpose.

(359) Thus the screening methods of the invention can be carried out in vitro or in vivo. For example, when the TERT promoter is in a cell, the cell may be in vitro or in vivo, and the determining of whether the compound is capable of inhibiting binding includes: (i) contacting the cell with an effective amount of the candidate TERT expression enhancing compound; and (ii) assessing whether the candidate compound inhibits binding of the transcriptional repressor protein/protein complex to the Site C binding site. In certain embodiments, inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site increases the proliferative capacity of the cell. In some embodiments, inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site delays the senescence of the cell. In yet additional embodiments, the TERT expression enhancing compound inhibits binding of the transcriptional repressor protein/protein complex to the Site C binding site. As such, determining whether a candidate TERT expression enhancing compound is capable of inhibiting binding of the transcriptional repressor protein/protein complex to the Site C binding site may be carried out by any number of methods, as well as combinations thereof.

(360) In certain embodiments, the screening protocol is or includes part of an assay selected from a potency assay, a compound or product release assay, and combinations thereof. The potency assay characterizes one or more biological activities of a compound of interest, where biological activity is characterized in general by TERT expression levels and/or inhibiting binding of the transcriptional repressor protein/protein complex to the Site C binding site of a TERT expression system. Such a potency assay may also be exploited in the development and/or validation of assays, as well as for a compound release assay. The compound release assay involves assessment of one or more of sterility, safety, purity, identity and potency of a compound of interest.

(361) Thus, in some embodiments, when the screening method employs a TERT expression enhancing compound that inhibits binding of the transcriptional repressor protein/protein complex to the Site C binding site, the TERT expression enhancing compound may be present as a pharmaceutical composition, e.g., as described above. In certain embodiments, the screening is a release assay for the pharmaceutical composition. In some embodiments, the screening is a potency assay for the pharmaceutical composition.

(362) Accordingly, in certain embodiments, the screening methods of the invention are carried out for compound release, such as to demonstrate and/or confirm that a compound, such as a pharmaceutical composition including the compound, is one or more of safe, pure, potent, effective and stable. As such, the screening methods of the invention may include demonstration of manufacturing and product consistency, including characterization for product release involving assessment of one or more of sterility, safety, purity, identity and potency.

(363) Of interest are screening methods of the invention that assess potency of a TERT expression enhancing compound of interest. By potency is intended the specific ability or capacity of a compound to effect a given result. Tests for potency may consist of either in vitro or in vivo tests, or both, which have been specifically adapted for each product so as to indicate its potency. Thus, potency assays indicate biological activity(s) specific/relevant to the product of interest. As noted above, the potency assays may include the generation of data regarding TERT expression and/or inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site. Such data may include, but is not limited to, qualitative and/or quantitative results for compound activity, lot release, predefined acceptance and/or rejection criteria (demonstrate lot to lot consistency), include appropriate reference material/controls, be validated for licensure, measure activity of one or more components that may be necessary for product activity, and/or indicate product stability.

(364) Potency measurements can be direct (e.g., biological assay) or indirect (e.g., surrogate assay(s) correlated to biological activity that may include one of many assays that measure product quality). For example, potency can be measured by simple identity markers that exhibit minimal variability from assay to assay over time, including functional biomarkers that correlate with cellular differentiation and senescence. This includes measurement of one or more of cellular proliferation, cellular survival, and/or senescence, as well as biomarkers from analytic, genomic and/or proteomic-based techniques that correlate to the biological activity of interest. For instance, determining expression of TERT and/or inhibition of binding of the transcriptional repressor protein/protein complex to the Site C binding site can include various approaches for indirect potency measurements, including analytical assays such as a non-bioassay method correlated to a unique and/or specific activity of the compound (e.g., immunochemical procedures such as ELISA, ELISPOT, Q-flow cytometry, quantitative western blots; and molecular and biochemical procedures such as enzymatic assays, Q-PCR, RT-PCR, microarray/genomics, proteomics).

(365) Thus potency measurement may be carried out in vivo in animal models or from clinical data (e.g., assessment of gene function, cell survival and so forth), and in vitro such as in cell and/or tissue culture (e.g., assessment of signaling pathways, proliferation, enzymatic activity, cell survival and so forth).

(366) Utility

(367) The TERT expression enhancing compounds, e.g., as described above, find use in a variety of applications. Applications of interest include, but are not limited to: therapeutic applications, research and manufacturing applications, and screening applications. Each of these different applications are now reviewed in greater details below.

(368) Therapeutic Applications

(369) TERT expression enhancing compounds of the invention find use in a variety of therapeutic applications. Therapeutic applications of interest include those applications in which reduced activity or expression of TERT (or shortened telomeres) is the cause or a compounding factor in disease progression. As such, the subject compounds find use in the treatment of a variety of different conditions in which the enhancement of TERT expression in the host is desired. Examples of disease conditions which may be treated with compounds of the invention include, but are not limited to: cancer, progeria, atherosclerosis, cardiovascular diseases, osteoarthritis, osteoporosis, Alzheimer's disease, macular degeneration, muscular dystrophy, dyskeratosis congenital, idiopathic pulmonary fibrosis, Cri du Chat syndrome, down's syndrome, Fanconi's Anemia, tuberous sclerosis, Werner's syndrome, conditions related to cell and tissue transplants, liver cirrhosis, rheumatoid arthritis, immune senescence, skin rejuvenation, bone marrow disorders, anemia, leukemia, lymphoma, and AIDS.

(370) One disease condition where compounds of the invention find use is Progeria. Progeria is a collection of syndromes all of which exhibit varying forms of premature aging. In many ways progeria parallels aging itself. The two most publicized forms of progeria are Hutchinson-Gilford syndrome, which strikes in early childhood, and Werner syndrome, which is an adult-onset disease. Children with Hutchinson-Gilford syndrome live an average of just under 13 years, dying primarily from atherosclerosis, usually cardiac or cardiovascular. People with Werner syndrome are usually diagnosed in their thirties and die in their forties. The progerias have been linked directly to premature telomere loss in a variety of cell types. Dyskeratosis congenita is rare progressive congenital disorder which results in premature aging as seen in progeria. It is thought to be primarily a disorder of poor telomere maintenance. The subject methods can be used in such conditions to further delay natural telomeric shortening and/or increase telomeric length, thereby treating these currently incurable syndromes. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(371) Another disease condition in which the subject compounds find use is Fanconi anemia (FA). FA is a genetic disease that affects children and adults from all ethnic backgrounds. FA is characterized by short stature, skeletal anomalies, increased incidence of solid tumors and leukemias, bone marrow failure (aplastic anemia), and cellular sensitivity to DNA damaging agents such as mitomycin C. FA is known to affect DNA repair and FA patients are more likely to develop bone marrow failure, myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(372) Another disease condition in which the subject compounds find use is in immune senescence. The effectiveness of the immune system decreases with age. Part of this decline is due to fewer T-lymphocytes in the system, a result of lost replicative capacity. Many of the remaining T-lymphocytes experience loss of function as their telomeres shorten and they approach senescence. The subject methods can be employed to inhibit immune senescence due to telomere loss. Because hosts with aging immune systems are at greater risk of developing pneumonia, cellulitis, influenza, and many other infections, the subject methods reduce morbidity and mortality due to infections. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(373) Another disease condition in which the subject compounds find use is AIDS. HIV, the virus that causes AIDS, invades white blood cells, particularly CD4 lymphocyte cells, and causes them to reproduce high numbers of the HIV virus, ultimately killing cells. In response to the loss of immune cells (typically about a billion per day), the body produces more CD8 cells to be able to suppress infection. This rapid cell division accelerates telomere shortening, ultimately hastening immune senescence of the CD8 cells. Anti-retroviral therapies have successfully restored the immune systems of AIDS patients, but survival depends upon the remaining fraction of the patient's aged T-cells. Once shortened, telomere length has not been naturally restored within cells. The subject methods can be employed to restore this length and/or prevent further shortening. As such the subject methods can spare telomeres and is useful in conjunction with the anti-retroviral treatments currently available for HIV/AIDS. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(374) Yet another type of disease condition in which the invention finds use is cardiovascular disease. The compounds of the invention can be employed to extend telomere length and replicative capacity of endothelial cells lining blood vessel walls (DeBono, Heart 80:110-1, 1998). Endothelial cells form the inner lining of blood vessels and divide and replace themselves in response to stress. Stresses include high blood pressure, excess cholesterol, inflammation, and flow stresses at forks in vessels. As endothelial cells age and can no longer divide sufficiently to replace lost cells, areas under the endothelial layer become exposed. Exposure of the underlying vessel wall increases inflammation, the growth of smooth muscle cells, and the deposition of cholesterol. As a result, the vessel narrows and becomes scarred and irregular, which contributes to even more stress on the vessel (Cooper, Cooke and Dzau, J Gerontol Biol Sci 49: 191-6, 1994). Aging endothelial cells also produce altered amounts of trophic factors (hormones that affect the activity of neighboring cells). These too contribute to increased clotting, proliferation of smooth muscle cells, invasion by white blood cells, accumulation of cholesterol, and other changes, many of which lead to plaque formation and clinical cardiovascular disease (Ibid.). By extending endothelial cell telomeres, the subject methods can be employed to combat the stresses contributing to vessel disease. Many heart attacks may be prevented if endothelial cells were enabled to continue to divide normally and better maintain cardiac vessels. The occurrence of strokes caused by the aging of brain blood vessels may also be significantly reduced by employing the subject methods to help endothelial cells in the brain blood vessels to continue to divide and perform their intended function. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(375) Yet another disease condition in which the subject compounds find use is the treatment of osteoporosis. Two types of cells interplay in osteoporosis: osteoblasts make bone and osteoclasts destroy it. Normally, the two are in balance and maintain a constant turnover of highly structured bone. In youth, bones are resilient, harder to break, and heal quickly. In old age, bones are brittle, break easily, and heal slowly and often improperly. Bone loss has been postulated to occur because aged osteoblasts, having lost much of their replicative capacity, cannot continue to divide at the rate necessary to maintain balance (Hazzard et al. PRINCIPLES OF GERIATRIC MEDICINE AND GERONTOLOGY, 2d ed. McGraw-Hill, New York City, 1994). The subject compounds can be employed to lengthen telomeres of osteoblast and osteoclast stem cells, thereby encouraging bone replacement and proper remodeling and reinforcement. The resultant stronger bone improves the quality of life for the many sufferers of osteoporosis and provides savings from fewer fracture treatments. The subject compounds and methods are generally part of a comprehensive treatment regime that also includes calcium, estrogen, and exercise. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(376) Yet another disease condition in which the subject compounds find use in the treatment of bone marrow disorders. The target may be a cell or population of cells which are treated according to the subject methods and then introduced into a multi-cellular organism for therapeutic effect. For example, the subject methods may be employed in bone marrow transplants for the treatment of cancer and skin grafts for burn victims. In these cases, cells are isolated from a human donor and then cultured for transplantation back into human recipients. During the cell culturing, the cells normally age and senesce, decreasing their useful lifespans. Bone marrow cells, for instance, lose approximately 40% of their replicative capacity during culturing. This problem is aggravated when the cells are first genetically engineered (Decary, Mouly et al. Hum Gene Ther 7(11): 1347-50, 1996). In such cases, the therapeutic cells must be expanded from a single engineered cell. By the time there are sufficient cells for transplantation, the cells have undergone the equivalent of 50 years of aging (Decary, Mouly et al. Hum Gene Ther 8(12): 1429-38, 1997). Use of the subject methods spares the replicative capacity of bone marrow cells and skin cells during culturing and expansion and thus significantly improves the survival and effectiveness of bone marrow and skin cell transplants. Any transplantation technology requiring cell culturing can benefit from the subject methods, including ex vivo gene therapy applications in which cells are cultured outside of the animal and then administered to the animal, as described in U.S. Pat. Nos. 6,068,837; 6,027,488; 5,824,655; 5,821,235; 5,770,580; 5,756,283; 5,665,350; the disclosures of which are herein incorporated by reference.

(377) The subject compounds further find use cell therapy treatment applications. Cell therapy involves the isolation of healthy human cells, the expansion of those cells ex vivo, and the reinfusion of the expanded cells into a patient. Cell therapy has application in the treatment of cancer and organ transplantation and many other disease states or conditions. For instance, bone marrow therapy takes advantage of the fact that bone marrow, the major organ of the immune system, is responsible for production of various cells in the blood from hematopoietic stem cells. Physicians treat hematological disorders such as anemia, leukemia, and lymphoma through bone marrow transplantation, in which bone marrow is removed from a donor (allogenic transplant) or a patient (autologous transplant) through general surgery, frozen and stored, and then transfused into the patient at a later date. Once transfused into the patient, the bone marrow cells gravitate to the bone marrow and engraft, eventually producing new blood cells either to increase the number of such cells in the anemic patient or to reconstitute the bone marrow destroyed as a result of chemotherapy or radiation therapy.

(378) Yet another disease condition in which the subject compounds find use is macular degeneration. Macular degeneration results in the gradual loss of central vision, ultimately leading to blindness. Some evidence points to the senescence of retinal pigment epithelial cells as the cause of macular degeneration. Applications of interest therefore include the treatment of macular degeneration by enhancing TERT expression in these cells. Similarly, the senescence of ocular keratocytes correlates with the development of cataracts and is another target for compounds of the invention. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(379) Yet another disease condition in which the subject compounds find use is hepatic cirrhosis. Hepatic cirrhosis causes many deaths each year and has no effective treatment. Liver cells normally turn over slowly and have excellent regenerative characteristics. In cirrhosis, however, regeneration is insufficient and abnormal leading ultimately to liver failure. Relengthening telomeres in liver cells with compounds of the invention delays or prevents loss of liver function and failure. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(380) Yet another disease condition in which the subject compounds find use is Alzheimer's disease. Most current research on this degenerative disease of the brain focuses on amyloid plaques and neurofibrillary tangles. Amyloid plaques are found outside the neurons, neurofibrillary plaques are found inside the neurons. Neuron cells do not divide at any significant rate so many people discount the role of telomere shortening in Alzheimer's disease and other dementias. However, neurons depend on glial and microglial cells for support, and these cells do divide continually. Relengthening of glial telomeres addresses the underlying cause of neuronal damage, and provides a treatment of Alzheimer's disease. Administration of TERT enhancing compounds of the invention to subjects suffering from this condition in accordance with methods of the invention, e.g., as described above, results in treatment of the subject for this condition.

(381) Additional disease conditions in which the subject methods find use are described in WO 99/35243, the disclosures of which are herein incorporated by reference.

(382) The subject compounds also find use in skin rejuvenation. The skin is the first line of defense of the immune system and shows the most visible signs of aging (West, Arch Dermatol 130(1):87-95, 1994). As skin ages, it thins, develops wrinkles, discolors, and heals poorly. Skin cells divide quickly in response to stress and trauma; but, over time, there are fewer and fewer actively dividing skin cells. Compounding the loss of replicative capacity in aging skin is a corresponding loss of support tissues. The number of blood vessels in the skin decreases with age, reducing the nutrients that reach the skin. Also, aged immune cells less effectively fight infection. Nerve cells have fewer branches, slowing the response to pain and increasing the chance of trauma. In aged skin, there are also fewer fat cells, increasing susceptibility to cold and temperature changes. Old skin cells respond more slowly and less accurately to external signals. They produce less vitamin D, collagen, and elastin, allowing the extracellular matrix to deteriorate. As skin thins and loses pigment with age, more ultraviolet light penetrates and damages skin. To repair the increasing ultraviolet damage, skin cells need to divide to replace damaged cells, but aged skin cells have shorter telomeres and are less capable of dividing (Fossel, REVERSING HUMAN AGING. William Morrow & Company, New York City, 1996).

(383) By practicing the subject methods, e.g., via administration of a compound of the invention topically, one can extend telomere length, and slow the downward spiral that skin experiences with age. Such a product not only helps protect a person against the impairments of aging skin; it also permits rejuvenated skin cells to restore youthful immune resistance and appearance. As such, compounds and methods of the invention may be employed to reduce the appearance of aging, e.g., by reducing the appearance of fine lines and wrinkles of the face and other locations of the body. The subject compounds and methods can be used for both medical and cosmetic skin rejuvenation applications.

(384) The subject compounds also find use in treatment of wounds and acute or chronic skin conditions, by increasing telomerase activity, cell proliferation or migration at the treatment site, epithelialization of the surface, closure of a wound if present, or restoration of normal physiological function. The subject compounds also find use in increasing the density of epithelial cells at the treatment site as a result of the applied therapy. The subject compounds also find use increasing telomerase activity in cells surrounding a wound to enhance wound healing. The subject compounds and methods can be used for skin rejuvenation and wound treatment applications. A topical composition including a compound may be used for treatment of acute or chronic conditions of the epidermis or for wound treatment and healing, e.g., such as a lotion, cream, gel, ointment, stick, spray, or paste.

(385) Compounds of the invention may be used for treating decubitus ulcers, sepsis, hypothermic stress, and other conditions of poor wound healing. Compounds could also be valuable in the production and use of skin grafts for severe burns and other conditions of traumatic skin loss.

(386) The subject compounds also find use in protecting cells against the harmful effects of exposure to UV and -radiation. Telomere dysfunction is linked to impaired DNA repair and radiosensitvity, and as such activation of TERT may counter or protect against the harmful effects of radiation induced stress on skin cells. The subject compounds and methods can be used for skin protection applications. A topical composition including a compound may be used as a sunscreen e.g., a lotion, cream, gel, ointment, stick, spray, or past; and optionally include a UV absorbing compound, a moisturizer, and other common components of sunscreens.

(387) The subject compounds also find use to induce the proliferation of hair follicles for growth of hair. Induction of TERT in skin epithelium causes a rapid transition from telogen, the resting phase of the hair follicle cycle, to anagen, the active phase, thereby facilitating robust hair growth. The subject compounds and methods can be used for hair rejuvenation applications. A topical or a nutraceutical composition including a compound may enhance hair growth, density or color, e.g., a shampoo, cream, hair gel, or hair spray.

(388) In addition to the above-described uses, the subject compounds can also be used to extend the lifespan of a mammal. By extend the lifespan is meant to increase the time during which the animal is alive, where the increase is generally 1% or more, such as 5% or more and including 10% or more as compared to a control.

(389) As indicated above, instead of a multicellular animal, the target may be a cell or population of cells which are treated according to the subject methods and then introduced into a multicellular organism for therapeutic effect. For example, the subject compounds may be employed in bone marrow transplants for the treatment of cancer and skin grafts for burn victims. In these cases, cells are isolated from a human donor and then cultured for transplantation back into human recipients. During the cell culturing, the cells normally age and senesce, decreasing their useful lifespans. Bone marrow cells, for instance, lose approximately 40% of their replicative capacity during culturing. This problem is aggravated when the cells are first genetically engineered (Decary, Mouly et al. Hum Gene Ther 7(11): 1347-50, 1996). In such cases, the therapeutic cells must be expanded from a single engineered cell. By the time there are sufficient cells for transplantation, the cells have undergone the equivalent of 50 years of aging (Decary, Mouly et al. Hum Gene Ther 8(12): 1429-38, 1997). Use of the subject compounds spares the replicative capacity of bone marrow cells and skin cells during culturing and expansion and thus significantly improves the survival and effectiveness of bone marrow and skin cell transplants. Any transplantation technology requiring cell culturing can benefit from the subject methods, including ex vivo gene therapy applications in which cells are cultured outside of the animal and then administered to the animal, as described in U.S. Pat. Nos. 6,068,837; 6,027,488; 5,824,655; 5,821,235; 5,770,580; 5,756,283; 5,665,350; the disclosures of which are herein incorporated by reference.

(390) The subject compounds also find use in countering the harmful effects of oxidative stress induced in the cells of newborn infants during the first 4 months of age. Newborns, and especially those delivered preterm, are more prone to oxidative stress than individuals later in life. Factors such as oxidative stress are modulators of telomere length. Telomere length has also been implicated as a modulating factor of genetic damage in newborns. Telomere dysfunction is linked to impaired DNA repair. As such, the subject compounds and methods can be used to protect against the harmful effects of oxidative stress. A composition (e.g. a topical or neutraceutical composition) including a compound may be used for treatment of oxidative stress injuries, e.g. a nutritional supplement for use in baby food or vitamin products, or a lotion, cream, shampoo, etc.

(391) The subject compounds also find use in countering the effects of abnormal or diminished levels of TERT activity in spermatogonia cells, their progenitors or descendants. The subject compounds and methods can be used in fertility applications, for example, by reversing abnormal or diminished levels of TERT activity in spermatogonia cells. A composition including a compound may be used for the treatment of infertility or disorders of reproduction.

(392) Research and Manufacturing Applications

(393) TERT expression enhancing compounds of the invention may find use in a variety addition applications, include research and manufacturing applications. For example, TERT expression enhancing compounds find use in applications for increasing the proliferative capacity of cells grown in vitro (e.g., immortalizing cells). As such, compounds of the invention find use in expanding cells for a variety uses, including expanding cells for use in diagnostic assays, expanding cells for use in preparative protocols (e.g., expanding antibody-producing cells or cells expressing a protein/factor of interest), expanding cells to facilitate studying the cells themselves (e.g., expanding rare stem cells harvested from a subject). The primary method of producing monoclonal antibodies requires the creation of immortalized antibody producing cells, called hybridomas, made by fusing B-lymphocytes (which secrete antibodies) with immortal (cancerous) myeloma cells to extend their life span. The fusion process can take from 8 to 12 months and represents approximately 25% of the cost of production. A compound of the invention could be used to extend the life span of B-lymphocytes directly, reducing the production startup time to, for example, 2 to 3 months.

(394) In addition, the compounds of the invention can be used to expand cells that will themselves be administered to a subject for experimental or therapeutic purposes, for example in expanding cells for genetic alteration (e.g., gene therapeutic purposes). As such, the compounds and methods of the invention are useful in any application in which an increase in cellular proliferation or a reduction in cellular senescence is advantageous.

(395) The subject compounds also find use in countering the effects of premature aging of cloned animals. A cloned animal inherits its age from its cell donor, thus being born old and die early. The length of the telomeres is related to the ageing problems of clones. Early embryonic telomere elongation is telomerase dependent, such that activation may lead to a rejuvenation of telomeres in cloned bovine embryos. The subject compounds also find use in cloning applications and may be used in a composition for use in agricultural cloning, such as in cloning of a cow or a sheep.

(396) Screening Applications

(397) The screening methods, e.g., as described above, find use in a variety of applications, including identifying and/or testing candidate TERT expression enhancing compounds use in a wide range of research and therapeutic applications, such as pharmaceutical development, manufacturing, and quality assurance/control, as well as immortalization of cell lines and treating conditions in a subject characterized by cellular senescence. Applications of interest include use of the screening methods of the invention for performing research, as well as for pharmaceutical compliance related to GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice also referred to as cGMP or current Good Manufacturing Practice)) and laboratory services. Thus the screening methods of the invention find broad use in research and lead development, sample analysis, as well as assay development, validation, drug regulatory submissions and compliance for new drug substances and drug products, drug product release and compound auditing in general. By compound auditing is meant quality assurance and/or quality control of a compound.

(398) Compound auditing in accordance with the subject screening methods may be exploited in multiple settings. One example is in assay development or simply to transfer an assay from one location to another, whether or not it requires GLP and/or GMP compliance. This aspect may include the use of the subject screening methods to ensure that a compound of interest performs consistently and provides continuity in an assay over time. Statistical data analysis and related relevant data analysis tools can be exploited to best match the compound and use of interest. For instance, the screening method can be performed under research level protocols to identify those parameters such as the limit of detection (LOD), the limit of quantitation (LOQ) and the linear range necessary for assay validation and/or transfer. As such, the screening methods find use in compiling and executing SOPs (Standard Operating Procedure or Standard Operating Protocol) which can be used for compound auditing.

(399) Additional uses of the screening methods of the invention include the generation and/or execution one or more GLP or GMP protocols that assess one or more of linearity, accuracy, precision, specificity, robustness, ruggedness and system suitability for one or more compounds of interest for a given end use. Generation of such protocols may include assays for identifying as well as testing of a compound of interest, including QA and/or QC, as well as generating controls that may be aliquoted under GLP or GMP compliance which may be used over several years depending upon the stability of the compound of interest.

(400) The subject screening methods may be used in qualitative and/or quantitative potency assays for routine lot release, lot comparisons, sampling, and stability assessment of a compound of interest.

(401) The screening methods may also be used in a multiple assay approach (i.e., assay matrix), such as when it is desirable to develop or use more than a single assay (e.g., an assay matrix often finds use when there is limited knowledge of product and mechanism of action, the product has multiple components with multiple biological activities, time is constrained due to limited product stability, biological assay is not quantitative and the like). Thus the subject screening methods may find use in a combination of assays where the combined results constitute an acceptable product release and/or potency assay (e.g., a quantitative physical assay along with a qualitative bioassay).

(402) Combination Therapy

(403) Aspects of the invention further include combination therapies. By combination therapy is meant that a compound of the invention can be used in a combination with another therapeutic agent to treat a single disease or condition. In particular embodiments, a compound of the invention is administered concurrently with the administration of another therapeutic agent, which can be administered as a component of a composition including the compound of the invention or as a component of a different composition. In particular embodiments, a composition including a compound of the invention is administered prior or subsequent to administration of another therapeutic agent.

(404) The compounds of the present invention can be administered in combination with other therapeutic agents in a variety of therapeutic applications. Therapeutic applications of interest for combination therapy include those applications in which reduced activity or expression of TERT (or shortened telomeres) is the cause or a compounding factor in disease progression. As such, the subject compounds find use in combination therapies in which the enhancement of TERT expression in the host is desired. Examples of disease conditions which may be treated by a combination therapy including a compound of the invention include, but are not limited to: cancer, progeria, atherosclerosis, cardiovascular diseases, osteoarthritis, osteoporosis, Alzheimer's disease, macular degeneration, muscular dystrophy, dyskeratosis congenital, idiopathic pulmonary fibrosis, Cri du Chat syndrome, down's syndrome, Fanconi's Anemia, tuberous sclerosis, Werner's syndrome, conditions related to cell and tissue transplants, liver cirrhosis, rheumatoid arthritis, immune senescence, skin rejuvenation, bone marrow disorders, anemia, leukemia, lymphoma, and AIDS. For example, combinations for anti-aging and AIDS therapy are discussed below.

(405) Combinations for Anti-Aging Therapy

(406) The compounds of the present invention can be administered in combination with other therapeutic agents as an anti-aging therapy.

(407) Over time, cell membranes may be damaged by reactive oxygen species and other free radicals, resulting, for example, in cross-linkage or cleavage of proteins and lipoproteins, and oxidation of membrane lipids and lipoproteins. Damage to the cell membrane can result in myriad changes including loss of cell permeability, increased intercellular ionic concentration, and decreased cellular capacity to excrete or detoxify waste products. As the intercellular ionic concentration of potassium increases, colloid density increases and m-RNA and protein synthesis are hampered, resulting in decreased cellular repair. Some cells become so dehydrated they cannot function at all. In aging, the regularity of tissue structure is lost, and individual cells enlarge, but the total number of cells decreases approximately 30%.

(408) To treat some effects of aging, for example as described above, compounds of the invention can be used in combination with an antioxidant. Examples of antioxidants include vitamin E, vitamin C, superoxide dismutase, glutathione, resveratrol, lipoic acid, carnosine, sulforaphane, and pioglitazone.

(409) Other compounds that have anti-aging effects and can be used in combination with compounds of the invention include (-)deprenyl (selegeline), 6-furfurylamino purine (kinetin), and 6-benzylamino purine (BAP). (-)Deprenyl (selegeline) can increase the formation of natural anti-oxidant enzymes SuperOxide Dismutase (SOD) and catalase. Cytokinins, such as 6-furfurylamino purine (kinetin) and 6-benzylamino purine (BAP), are known to be growth stimulators. Kinetin promotes cell division.

(410) In some instances, compounds of the invention are administered in conjunction with resveratrol, or an analog thereof. 3,4,5-trihydroxystilbene commonly known as resveratrol is found in grapes. Resveratrol is found to exhibit antioxidative and antimutagenic properties. Resveratrol is also an inducer of phase II drug metabolizing enzymes. In humans, resveratrol consumption is found to inhibit peroxidation of plasma low density lipoprotein and this effect has been proposed to protect against the development of atherosclerosis. The above referenced bioprotective properties of resveratrol are attributed to the presence of phenolic groups in its structure. Also of interest are resveratrol analogs, such as those describe din U.S. Pat. No. 7,026,518; the disclosure of which is herein incorporated by reference.

(411) Combinations for AIDS Therapy

(412) The compounds of the present invention can be administered jointly with other therapeutics in order to enhance antiviral efficacy. The present compounds can be administered with antiviral agents, including (but not limited to) agents acting on any suitable target in the virus replication process, such as reverse transcriptase inhibitors, viral protease inhibitors and glycosylation inhibitors, etc; antiviral agents acting on different targets all through the virus spreading process; antiviral agents acting on different sites of the same molecule; and antiviral agents capable of preventing or reducing the development of the drug resistance.

(413) In certain embodiments, compounds of the invention can be administered jointly with retrovirus inhibitors, including (but not limited to) nucleoside analogs. The nucleoside derivatives, in the absence of any 3-substituent that can be bound to other nucleosides, can suppress the synthesis of cDNA catalyzed by reverse transcriptase and thereby terminate the viral DNA replication. This is why they become anti-HIV therapeutic agents. For example, AZT and ddT, both of them can suppress HIV-1 replication in vivo and in vitro, had been approved as remedies for HIV infection and AIDS.

(414) The present compounds can be administered jointly with nucleoside derivatives and non-nucleoside derivatives. The nucleoside derivatives include (but not limited to): 2,3-dideoxyadenosine (ddA); 2,3-diseoxyguanosine (ddG); 2,3-dideoxyinosine (ddI); 2,3-dideoxycytidine (ddC); 2,3-dideoxythymidine (ddT); 2,3-dideoxy-dideoxythymidine (d4T) and 3-azide2,3-dideoxycytidine (AZT). According to an embodiment of the present invention, the nucleoside derivatives are halonucleoside, preferably 2 3-dideoxy-2-fluoronuceotides, including (but not limited to): 2,3-dideoxy-2-fluoroadenosine; 2,3-dideoxy-2-fluoroinosine; 2,3-dideoxy-2-fluorothymidine; 2,3-dideoxy-2-fluorocytidine; and 2,3-dideoxy-2,3-didehydro-2-fluoronuceotides, including (but not limited to): 2,3-dideoxy-2,3-didehydro-2fluorothymidine (Fd4T).

(415) The present compounds can also be administered jointly with inhibitors of uridine phosphorylating enzyme, including (but not limited to) acyclouridine compounds, including benzylacyclouridine (BAU); benzoxybenzylacyclouridine (BBAU); amethobenzylacyclouridine (AMBAU); amethobenzoxybenzylacyclouridine (AMB-BAU); hydroxymethylbenzylacyclouridine (HMBAU); and hydroxymethylbenzoxybenzylacyclouridine (HMBBAU).

(416) The present compounds can also be administered jointly with cytokines or cytokine inhibitors, including (but not limited to): rIFN, rIFN, and rIFN, TNF inhibitors, MNX-160, human r interferon A, human r interferon, and human r interferon.

(417) Protease inhibitors prevent the virus from maturing mainly during the viral assembly period or after the assembly period (namely during the viral budding). Protease inhibitors show an antiviral activity both in vivo and in vitro. After being administered protease inhibitors, the AIDS patient HIV-level exhibits an exponential decline and their CD4 lymphocytes rise in number (Deeks, et al., 1997, JAMA 277:145-53). Aspects of the present invention provide for administration of the present compounds together with a protease inhibitor, the latter including (but not limited to): Indinavir, Invirase, Norvir, Viracept, and Agenerase.

(418) The present compounds can also be used jointly with anti-HIV drugs that disturb 5-mRNA processing, such as virazole. The acting mechanism of virazole is unknown yet and presumed to be competing with guanine in forming the mRNA capping structure, and/or disturbing the methylation of these molecules.

(419) In addition, the present compounds can be administered jointly with amphotericin B. Amphotericin B is a polyene antifungal antibiotic that can bind irreversibly with sterol. Amphotericin B and its formate have an inhibiting effect against many lipid envelop viruses including HIV.

(420) The present compounds can also be administered jointly with the glycoprotein processing inhibitor castanospermine, which is a vegetable alkaloid capable of inhibiting glycol protein processing. HIV envelope contains two large glycoproteins gp120 and gp41. The glycosylation of proteins plays an important role in the interactions between gp120 and CD4. The progeny virus synthesized in the presence of castanospermine has a weaker infectivity than the parental virus.

(421) Drug combinations of interest include the present compounds, and at least one of other antiviral agents, such as reverse transcriptase inhibitors, protease inhibitors, mRNA processing inhibitors, protein glycosylation inhibitors, virus adsorbent, CD4 receptor inhibitors, chemokine co-receptor inhibitors, neutralizing antibody, integrase inhibitors, and other fusion inhibitors, including (but not limited to) nucleoside analogs or chain terminators; chemokine co-receptor inhibitors AMD-3100 (Tremblay, C. L. et al., 2000, J. AIDS 1:25(2)99-10).

(422) According to an embodiment of the present invention, therapeutic agents that can be used jointly with the present compounds include (but not limited to): 2-deoxy-D-glucose (2dG1c), deoxynojirimycinacycloguanosine, virazole, rifadin, adamantanamine, rifabutine, ganciclover (DHPG), famciclove, buciclover (DHBG), fluoroiodoaracytosine, iodoxuridine, trifluorothymidine, ara-A, ara-AMP, bromovinyldeoxyuridine, BV-arau, 1-b-D-glycoarabinofuranoside-E-5-[2-bromovinyl]uracil, adamantethylamine, hydroxyurea, phenylacetic heptanedione, diarylamidine, (S)-(p-nitrobenzyl)-6-thioinosine and phosphonoformate.

(423) Systems and Kits

(424) Also provided are systems and kits that include compounds of the invention. Systems of the invention are collections of active agents brought together, e.g., by a health care practitioner, for administration to a subject, such as a patient. Such systems may include TERT expression enhancing compound of the invention and one or more additional active agents. Kits that include TERT expression enhancing compounds of the invention are also provided. Kits of the invention may include one or more dosages of a TERT expression enhancing compound, and optionally one or more dosages of one or more additional active agents. Conveniently, the formulations may be provided in a unit dosage format. In such kits, in addition to the containers containing the formulation(s), e.g. unit doses, is an informational package insert describing the use of the subject formulations in the methods of the invention, e.g., instructions for using the subject unit doses to treat cellular proliferative disease conditions.

(425) These instructions may be present in the subject systems and kits in a variety of forms, one or more of which may be present in the kit. One form in which these instructions may be present is as printed information on a suitable medium or substrate, e.g., a piece or pieces of paper on which the information is printed, in the packaging of the kit, in a package insert, etc. Yet another means would be a computer readable medium, e.g., diskette, CD, etc., on which the information has been recorded. Yet another means that may be present is a website address which may be used via the internet to access the information at a removed site. Any convenient means may be present in the kits.

(426) The following examples are offered by way of illustration and not by way of limitation.

EXPERIMENTAL

(427) Telomerase is a ribonucleoprotein complex composed of the catalytic protein subunit (human telomerase reverse transcriptase or hTERT) and the RNA template. hTERT expression level can be measured by PCR.

(428) Quantitative Reverse Transcription PCR

(429) Quantitative Reverse Transcription PCR can be run according to procedures outlined in Yajima et al. (Yajima, T. et al. Quantitative Reverse Transcription-PCR Assay of the RNA Component of Human Telomerase Using the TaqMan Fluorogenic Detection System Clinical Chemistry, 44:12, 2441-2445, 1998).

(430) Real-Time PCR.

(431) The principle of real-time PCR was first described by Heid et al. (Heid C. A., Stevens J., Livak K. J., Williams P. M. Real time quantitative PCR. Genome Res., 6:986-994, 1996). Briefly, amplification of the target sequence is monitored per PCR cycle by detecting the fluorescence signal emitted by an internal probe that is degraded by the 5 nuclease activity of the Taq polymerase. The emission signal accumulates in each sample, and the C.sub.t required to reach a given fluorescence threshold is determined (C.sub.t stands for Cycle Threshold and is a measure of the number of PCR cycles that are required to amplify a targetthus, a lower C.sub.t score means that there is more abundant hTERT mRNA). Thus, the C.sub.t value of a sample inversely correlates to the quantity of the starting cDNA which correlates to the number of mRNA transcripts. Using the cDNA of known quantity, a standard curve can be generated and used to determine the starting amount of mRNA transcripts based on the C.sub.1 value of each sample.

(432) Quantitative real-time PCR can be done on cDNA from test compound-treated and nontreated cells by use of a ABI Prism 7900 Sequence Detection System (PE Applied Biosystems, Foster City, CA) following the Assays-on-Demand protocol (PE Applied Biosystems, Foster City, CA). Quantitative data can be analyzed using the Sequence Detection System software version 2.1 (PE Applied Biosystems).

(433) Cell Viability Assay

(434) Cell viability is determined using a homogeneous method, such as CellTiter-Glo Luminescent Cell Viability Assay (Promega Corporation, Madison, WI.) to determine the number of viable cells in culture These assays are based on quantitation of the ATP present, which signals the presence of metabolically active cells. Luminescent values of compound treated cells are compared to that of cells treated with vehicle alone to determine the average cell viability as a percent of control.

(435) The following compounds were tested in assays designed to identify compounds that enhance human TERT expression. The compounds turned on human TERT expression in these assays.
