[0611] Another embodiment of the present invention is a pharmaceutical composition comprising one or more pharmaceutically acceptable carrier and/or diluent and a compound disclosed herein, or a pharmaceutically acceptable salt thereof.

[0612] “Pharmaceutically acceptable carrier” and “pharmaceutically acceptable diluent” means non-therapeutic components that are of sufficient purity and quality for use in the formulation of a composition of the invention that, when appropriately administered to an animal or human, typically do not produce an adverse reaction, and that are used as a vehicle for a drug substance (i.e., a compound of the present invention).

[0613] Pharmaceutically acceptable salts of the compounds of the present invention are also included. For example, an acid salt of a compound of the present invention containing an amine or other basic group can be obtained by reacting the compound with a suitable organic or inorganic acid, resulting in pharmaceutically acceptable anionic salt forms. Examples of anionic salts include the acetate, benzenesulfonate, benzoate, bicarbonate, bitartrate, bromide, calcium edetate, camsylate, carbonate, chloride, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, glyceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isethionate, lactate, lactobionate, malate, maleate, mandelate, mesylate, methylsulfate, mucate, napsylate, nitrate, pamoate, pantothenate, phosphate/diphosphate, polygalacturonate, salicylate, stearate, subacetate, succinate, sulfate, tannate, tartrate, teoclate, tosylate, and triethiodide salts.

[0614] Salts of the compounds of the present invention containing a carboxylic acid or other acidic functional group can be prepared by reacting with a suitable base. Such a pharmaceutically acceptable salt may be made with a base which affords a pharmaceutically acceptable cation, which includes alkali metal salts (especially sodium and potassium), alkaline earth metal salts (especially calcium and magnesium), aluminum salts and ammonium salts, as well as salts made from physiologically acceptable organic bases such as trimethylamine, triethylamine, morpholine, pyridine, piperidine, picoline, dicyclohexylamine, N,N′-dibenzylethylenediamine, 2-hydroxyethylamine, bis-(2-hydroxyethyl)amine, tri-(2-hydroxyethyl)amine, procaine, dibenzylpiperidine, dehydroabietylamine, N,N′-bisdehydroabietylamine, glucamine, N-methylglucamine, collidine, quinine, quinoline, and basic amino acids such as lysine and arginine.

[0615] The invention also includes various isomers and mixtures thereof. Certain of the compounds of the present invention may exist in various stereoisomeric forms. Stereoisomers are compounds which differ only in their spatial arrangement. Enantiomers are pairs of stereoisomers whose mirror images are not superimposable, most commonly because they contain an asymmetrically substituted carbon atom that acts as a chiral center. “Enantiomer” means one of a pair of molecules that are mirror images of each other and are not superimposable. Diastereomers are stereoisomers that are not related as mirror images, most commonly because they contain two or more asymmetrically substituted carbon atoms. “R” and “S” represent the configuration of substituents around one or more chiral carbon atoms. When a chiral center is not defined as R or S, either a pure enantiomer or a mixture of both configurations is present.

[0616] “Racemate” or “racemic mixture” means a compound of equimolar quantities of two enantiomers, wherein such mixtures exhibit no optical activity; i.e., they do not rotate the plane of polarized light.

[0617] The compounds of the invention may be prepared as individual isomers by either isomer-specific synthesis or resolved from an isomeric mixture. Conventional resolution techniques include forming the salt of a free base of each isomer of an isomeric pair using an optically active acid (followed by fractional crystallization and regeneration of the free base), forming the salt of the acid form of each isomer of an isomeric pair using an optically active amine (followed by fractional crystallization and regeneration of the free acid), forming an ester or amide of each of the isomers of an isomeric pair using an optically pure acid, amine or alcohol (followed by chromatographic separation and removal of the chiral auxiliary), or resolving an isomeric mixture of either a starting material or a final product using various well known chromatographic methods.

[0618] When the stereochemistry of a disclosed compound is named or depicted by structure, the named or depicted stereoisomer is at least about 60%, about 70%, about 80%, about 90%, about 99% or about 99.9% by weight pure relative to the other stereoisomers. When a single enantiomer is named or depicted by structure, the depicted or named enantiomer is at least about 60%, about 70%, about 80%, about 90%, about 99% or about 99.9% by weight optically pure. Percent optical purity by weight is the ratio of the weight of the enantiomer that is present divided by the combined weight of the enantiomer that is present and the weight of its optical isomer.

[0619] “Cis” means on the same side. “Trans” means on opposite sides. The designation “cis” is used when two substituents have an “up-up” or a “down-down” relationship. The designation “trans” is used when two substituents have an “up-down” or “down-up” relationship. Typically, two substituents that are “cis” to one another are arranged on the same side of a molecule. When the term “cis” is used with reference to a fused, saturated or partially saturated ring system, the term is intended to indicate that the two atoms attached to the common ring atoms are cis substituents. For example,

##STR01250##

are cis diastereomers of a moiety having the following structural formula:

##STR01251##

[0620] As used herein, the term “subject” means a mammal in need of treatment or prevention, e.g., a human, companion animals (e.g., dogs, cats, and the like), farm animals (e.g., cows, pigs, horses, sheep, goats and the like) and laboratory animals (e.g., rats, mice, guinea pigs and the like). Typically, the subject is a human in need of the specified treatment.

[0621] As used herein, the term “treating” or ‘treatment” refers to obtaining desired pharmacological and/or physiological effect. The effect can include achieving, partially or substantially, one or more of the following results: partially or totally reducing the extent of the disease, disorder or syndrome; ameliorating or improving a clinical symptom or indicator associated with the disorder; delaying, inhibiting or decreasing the likelihood of the progression of the disease, disorder or syndrome.

[0622] As used herein, “preventing” or “prevention” refers to reducing the likelihood of the onset or development of disease, disorder or syndrome.

[0623] “Effective amount” means that amount of active compound agent that elicits the desired biological response in a subject. In one embodiment, the effective amount of a compound of the invention is from about 0.01 mg/kg/day to about 1000 mg/kg/day, from about 0.1 mg/kg/day to about 100 mg/kg/day, or from about 0.5 mg/kg/day to about 50 mg/kg/day.

[0624] As used herein the terms hematological malignancy and hematological cancer are used interchangeably and refer to cancers of the blood (leukemia) or cancers of the lymph system (lymphomas). Leukemias can include acute myeloid leukemia (AML), also known as acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia or acute nonlymphocytic leukemia, acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), chronic myelogenous leukemia (CML), chronic myelomonocytic leukemia (CMML), acute monocytic leukemia (AMoL). Lymphomas can include, Hodgkin's lymphoma, non-Hodgkin's lymphomas, multiple myeloma, myelodysplastic or myeloproliferative syndrome, mantle cell lymphoma, diffuse large B-cell lymphoma (DLBCL), Burkitt lymphoma/leukemia and B-cell lymphoma.

Indications

[0625] Hematological malignancies are cancers that affect the blood and lymph system. Some types of hematologic malignancies include: Multiple myeloma, Hodgkin's lymphoma, Non-Hodgkin's lymphoma and Leukemia. The cancer may begin in blood-forming tissue (e.g., bone marrow), or in the cells of the immune system. For example, leukemia originates in blood-forming tissue. Leukemia is characterized by the uncontrolled growth of blood cells, usually white blood cells (leukocytes), in the bone marrow. White blood cells are a fundamental component of the body's immune response. The leukemia cells crowd out and replace normal blood and marrow cells.

[0626] There are four main types of leukemia: Acute myeloid leukemia (AML); Chronic myeloid leukemia (CML); Acute lymphocytic leukemia (ALL); and Chronic lymphocytic leukemia (CLL). The primary differences between the four main types of leukemia have to do with their rates of progression and where the cancer develops. Acute myeloid leukemia (AML), also known as acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia or acute nonlymphocytic leukemia, is a fast-growing form of cancer of the blood and bone marrow. AML is the most common type of acute leukemia. It occurs when the bone marrow begins to make blasts, cells that have not yet completely matured. These blasts normally develop into white blood cells. However, in AML, these cells do not develop and are unable to ward off infections. In AML, the bone marrow may also make abnormal red blood cells and platelets. The number of these abnormal cells increases rapidly, and the abnormal (leukemia) cells begin to crowd out the normal white blood cells, red blood cells and platelets that the body needs.

Cancer Combination Therapies

[0672] In some embodiments, a compound described herein is administered together with an additional cancer treatment. Exemplary cancer treatments include, for example, chemotherapy, targeted therapies such as antibody therapies, kinase inhibitors, immunotherapy, and hormonal therapy, and anti-angiogenic therapies. Examples of each of these treatments are provided below.

[0673] As used herein, the term “combination,” “combined,” and related terms refer to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention can be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the invention, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.

[0674] The amount of both a compound of the invention and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above) that can be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. For example, compositions of this invention should be formulated so that a dosage of between 0.01-100 mg/kg body weight/day of a compound of the invention can be administered.

Chemotherapy

[0675] In some embodiments, a compound described herein is administered with a chemotherapy. Chemotherapy is the treatment of cancer with drugs that can destroy cancer cells. “Chemotherapy” usually refers to cytotoxic drugs which affect rapidly dividing cells in general, in contrast with targeted therapy. Chemotherapy drugs interfere with cell division in various possible ways, e.g., with the duplication of DNA or the separation of newly formed chromosomes. Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

[0676] Examples of chemotherapeutic agents used in cancer therapy include, for example, antimetabolites (e.g., folic acid, purine, and pyrimidine derivatives) and alkylating agents (e.g., nitrogen mustards, nitrosoureas, platinum, alkyl sulfonates, hydrazines, triazenes, aziridines, spindle poison, cytotoxic agents, topoisomerase inhibitors and others). Exemplary agents include Aclarubicin, Actinomycin, Alitretinon, Altretamine, Aminopterin, Aminolevulinic acid, Amrubicin, Amsacrine, Anagrelide, Arsenic trioxide, Asparaginase, Atrasentan, Belotecan, Bexarotene, Bendamustine, Bleomycin, Bortezomib, Busulfan, Camptothecin, Capecitabine, Carboplatin, Carboquone, Carmofur, Carmustine, Celecoxib, Chlorambucil, Chlormethine, Cisplatin, Cladribine, Clofarabine, Crisantaspase, Cyclophosphamide, Cytarabine, Dacarbazine, Dactinomycin, Daunorubicin, Decitabine, Demecolcine, Docetaxel, Doxorubicin, Efaproxiral, Elesclomol, Elsamitrucin, Enocitabine, Epirubicin, Estramustine, Etoglucid, Etoposide, Floxuridine, Fludarabine, Fluorouracil (5FU), Fotemustine, Gemcitabine, Gliadel implants, Hydroxycarbamide, Hydroxyurea, Idarubicin, Ifosfamide, Irinotecan, Irofulven, Ixabepilone, Larotaxel, Leucovorin, Liposomal doxorubicin, Liposomal daunorubicin, Lonidamine, Lomustine, Lucanthone, Mannosulfan, Masoprocol, Melphalan, Mercaptopurine, Mesna, Methotrexate, Methyl aminolevulinate, Mitobronitol, Mitoguazone, Mitotane, Mitomycin, Mitoxantrone, Nedaplatin, Nimustine, Oblimersen, Omacetaxine, Ortataxel, Oxaliplatin, Paclitaxel, Pegaspargase, Pemetrexed, Pentostatin, Pirarubicin, Pixantrone, Plicamycin, Porfimer sodium, Prednimustine, Procarbazine, Raltitrexed, Ranimustine, Rubitecan, Sapacitabine, Semustine, Sitimagene ceradenovec, Strataplatin, Streptozocin, Talaporfin, Tegafur-uracil, Temoporfin, Temozolomide, Teniposide, Tesetaxel, Testolactone, Tetranitrate, Thiotepa, Tiazofurine, Tioguanine, Tipifarnib, Topotecan, Trabectedin, Triaziquone, Triethylenemelamine, Triplatin, Tretinoin, Treosulfan, Trofosfamide, Uramustine, Valrubicin, Verteporfin, Vinblastine, Vincristine, Vindesine, Vinflunine, Vinorelbine, Vorinostat, Zorubicin, and other cytostatic or cytotoxic agents described herein.

[0677] Because some drugs work better together than alone, two or more drugs are often given at the same time. Often, two or more chemotherapy agents are used as combination chemotherapy. In some embodiments, the chemotherapy agents (including combination chemotherapy) can be used in combination with a compound described herein.

[0678] In a specific embodiment, the two additional therapeutic agents used in combination with the compounds of the invention and include, cytarabine (ara-C) and an anthracycline drug such as daunorubicin (daunomycin) or idarubicin. In certain instances, a third additional agent, cladribine, is used.

Targeted Therapy

[0679] Targeted therapy constitutes the use of agents specific for the deregulated proteins of cancer cells. Small molecule targeted therapy drugs are generally inhibitors of enzymatic domains on mutated, overexpressed, or otherwise critical proteins within a cancer cell. Prominent examples are the tyrosine kinase inhibitors such as axitinib, bosutinib, cediranib, desatinib, erolotinib, imatinib, gefitinib, lapatinib, lestaurtinib, nilotinib, semaxanib, sorafenib, sunitinib, and vandetanib, and also cyclin-dependent kinase inhibitors such as alvocidib and seliciclib. Monoclonal antibody therapy is another strategy in which the therapeutic agent is an antibody which specifically binds to a protein on the surface of the cancer cells. Examples include the anti-HER2/neu antibody trastuzumab (Herceptin®) typically used in breast cancer, and the anti-CD20 antibody rituximab and tositumomab typically used in a variety of B-cell malignancies. Other exemplary antibodies include cetuximab, panitumumab, trastuzumab, alemtuzumab, bevacizumab, edrecolomab, and gemtuzumab. Exemplary fusion proteins include aflibercept and denileukin diftitox. In some embodiments, targeted therapy can be used in combination with a compound described herein, e.g., Gleevec (Vignari and Wang 2001).

[0680] Targeted therapy can also involve small peptides as “homing devices” which can bind to cell surface receptors or affected extracellular matrix surrounding a tumor. Radionuclides which are attached to these peptides (e.g., RGDs) eventually kill the cancer cell if the nuclide decays in the vicinity of the cell. An example of such therapy includes BEXXAR®.

Pharmaceutical Formulations

[0681] The compositions of the invention include ocular, oral, nasal, transdermal, topical with or without occlusion, intravenous (both bolus and infusion), inhalable, and injection (intraperitoneally, subcutaneously, intramuscularly, intratumorally, or parenterally) formulations. The composition may be in a dosage unit such as a tablet, pill, capsule, powder, granule, liposome, ion exchange resin, sterile ocular solution, or ocular delivery device (such as a contact lens and the like facilitating immediate release, timed release, or sustained release), parenteral solution or suspension, metered aerosol or liquid spray, drop, ampoule, auto-injector device, or suppository; for administration ocularly, orally, intranasally, sublingually, parenterally, or rectally, or by inhalation or insufflation.

[0682] Compositions of the invention suitable for oral administration include solid forms such as pills, tablets, caplets, capsules (each including immediate release, timed release, and sustained release formulations), granules and powders; and, liquid forms such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for ocular administration include sterile solutions or ocular delivery devices. Forms useful for parenteral administration include sterile solutions, emulsions, and suspensions.

[0683] The compositions of the invention may be administered in a form suitable for once-weekly or once-monthly administration. For example, an insoluble salt of the active compound may be adapted to provide a depot preparation for intramuscular injection (e.g., a decanoate salt) or to provide a solution for ophthalmic administration.

[0684] The dosage form containing the composition of the invention contains an effective amount of the active ingredient necessary to provide a therapeutic effect. The composition may contain from about 5,000 mg to about 0.5 mg (preferably, from about 1,000 mg to about 0.5 mg) of a compound of the invention or salt form thereof and may be constituted into any form suitable for the selected mode of administration. The composition may be administered about 1 to about 5 times per day. Daily administration or post-periodic dosing may be employed.

[0685] For oral administration, the composition is preferably in the form of a tablet or capsule containing, e.g., about 500 to about 0.5 milligrams of the active compound. Dosages will vary depending on factors associated with the particular patient being treated (e.g., age, weight, diet, and time of administration), the severity of the condition being treated, the compound being employed, the mode of administration, and the strength of the preparation.

[0686] The oral composition is preferably formulated as a homogeneous composition, wherein the active ingredient is dispersed evenly throughout the mixture, which may be readily subdivided into dosage units containing equal amounts of a compound of the invention. Preferably, the compositions are prepared by mixing a compound of the invention (or pharmaceutically acceptable salt thereof) with one or more optionally present pharmaceutical carriers (such as a starch, sugar, diluent, granulating agent, lubricant, glidant, binding agent, and disintegrating agent), one or more optionally present inert pharmaceutical excipients (such as water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and syrup), one or more optionally present conventional tableting ingredients (such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate, and any of a variety of gums), and an optional diluent (such as water).

[0687] Binder agents include starch, gelatin, natural sugars (e.g., glucose and beta-lactose), corn sweeteners and natural and synthetic gums (e.g., acacia and tragacanth). Disintegrating agents include starch, methyl cellulose, agar, and bentonite.

[0688] Tablets and capsules represent an advantageous oral dosage unit form. Tablets may be sugarcoated or filmcoated using standard techniques. Tablets may also be coated or otherwise compounded to provide a prolonged, control-release therapeutic effect. The dosage form may comprise an inner dosage and an outer dosage component, wherein the outer component is in the form of an envelope over the inner component. The two components may further be separated by a layer which resists disintegration in the stomach (such as an enteric layer) and permits the inner component to pass intact into the duodenum or a layer which delays or sustains release. A variety of enteric and non-enteric layer or coating materials (such as polymeric acids, shellacs, acetyl alcohol, and cellulose acetate or combinations thereof) may be used.

[0689] Compounds of the invention may also be administered via a slow release composition; wherein the composition includes a compound of the invention and a biodegradable slow release carrier (e.g., a polymeric carrier) or a pharmaceutically acceptable non-biodegradable slow release carrier (e.g., an ion exchange carrier).

[0690] Biodegradable and non-biodegradable slow release carriers are well known in the art. Biodegradable carriers are used to form particles or matrices which retain an active agent(s) and which slowly degrade/dissolve in a suitable environment (e.g., aqueous, acidic, basic and the like) to release the agent. Such particles degrade/dissolve in body fluids to release the active compound(s) therein. The particles are preferably nanoparticles or nanoemulsions (e.g., in the range of about 1 to about 500 nm in diameter, preferably about 50 to about 200 nm in diameter, and most preferably about 100 nm in diameter). In a process for preparing a slow release composition, a slow release carrier and a compound of the invention are first dissolved or dispersed in an organic solvent. The resulting mixture is added into an aqueous solution containing an optional surface-active agent(s) to produce an emulsion. The organic solvent is then evaporated from the emulsion to provide a colloidal suspension of particles containing the slow release carrier and the compound of the invention.

[0691] The compound disclosed herein may be incorporated for administration orally or by injection in a liquid form such as aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil and the like, or in elixirs or similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone, and gelatin. The liquid forms in suitably flavored suspending or dispersing agents may also include synthetic and natural gums. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations, which generally contain suitable preservatives, are employed when intravenous administration is desired.

[0692] The compounds may be administered parenterally via injection. A parenteral formulation may consist of the active ingredient dissolved in or mixed with an appropriate inert liquid carrier. Acceptable liquid carriers usually comprise aqueous solvents and other optional ingredients for aiding solubility or preservation. Such aqueous solvents include sterile water, Ringer's solution, or an isotonic aqueous saline solution. Other optional ingredients include vegetable oils (such as peanut oil, cottonseed oil, and sesame oil), and organic solvents (such as solketal, glycerol, and formyl). A sterile, non-volatile oil may be employed as a solvent or suspending agent. The parenteral formulation is prepared by dissolving or suspending the active ingredient in the liquid carrier whereby the final dosage unit contains from about 0.005 to about 10% by weight of the active ingredient. Other additives include preservatives, isotonizers, solubilizers, stabilizers, and pain-soothing agents. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed.

[0693] Compounds of the invention may be administered intranasally using a suitable intranasal vehicle.

[0694] In another embodiment, the compounds of this invention may be administered directly to the lungs by inhalation.

[0695] Compounds of the invention may also be administered topically or enhanced by using a suitable topical transdermal vehicle or a transdermal patch.

[0696] For ocular administration, the composition is preferably in the form of an ophthalmic composition. The ophthalmic compositions are preferably formulated as eye-drop formulations and filled in appropriate containers to facilitate administration to the eye, for example a dropper fitted with a suitable pipette. Preferably, the compositions are sterile and aqueous based, using purified water. In addition to the compound of the invention, an ophthalmic composition may contain one or more of: a) a surfactant such as a polyoxyethylene fatty acid ester; b) a thickening agents such as cellulose, cellulose derivatives, carboxyvinyl polymers, polyvinyl polymers, and polyvinylpyrrolidones, typically at a concentration n the range of about 0.05 to about 5.0% (wt/vol); c) (as an alternative to or in addition to storing the composition in a container containing nitrogen and optionally including a free oxygen absorber such as Fe), an anti-oxidant such as butylated hydroxyanisol, ascorbic acid, sodium thiosulfate, or butylated hydroxytoluene at a concentration of about 0.00005 to about 0.1% (wt/vol); d) ethanol at a concentration of about 0.01 to 0.5% (wt/vol); and e) other excipients such as an isotonic agent, buffer, preservative, and/or pH-controlling agent. The pH of the ophthalmic composition is desirably within the range of 4 to 8.

[0697] While this invention has been particularly shown and described with references to example embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.

[0706] Compounds 1, 2, 3a, 4a and 5 and the Compounds of FIGS. 15A-15M, 16A-16F and 17A-17D were assayed for tumor cell proliferation using AML cancer cell lines THP-1 and MV4-11. The inhibition of cytrochrome-oxidase 1 (COX-1) expression in MV4-11 cells was also measured for Compounds 1, 2, 3a, 4a and 5.

[0707] A. THP-1 Anti-Proliferation Assay

[0708] The inhibition of eukaryotic cell culture growth was established using THP-1 cells (ATCC Cat. #TIB-202), a human acute monocytic leukemia cell line. These are suspension cells. This cell-based assay for eukaryotic culture growth inhibition was performed in 384-well plate format to determine the in vitro cytotoxicity of the test compounds.

[0709] Compounds were solubilized in water. Compounds were diluted 1:2 in assay media and 1:2 serial dilutions were performed in 50:50 media:water mix. The high dose was 40 μM, 10% water final. 5 μL of compound at 5× the final concentration was dispensed to the 384 assay plate. 20 μL of THP-1 cells were added.

[0710] Compounds were plated in dose response format (10% water final concentration), followed by the addition of cells. Cells were grown and incubated with compounds in RPMI-1640 medium/pen/strep/L-glutamine/10% FBS/2-mercaptoethanol for 72 hr at 37° C. with 5% CO.sub.2. At the end of the incubation time, cells were assayed for viability using Cell Titer GLO (Promega). Compounds that were considered cytotoxic resulted in a decreased luminescent signal.

[0711] B. MV4-11 Anti-Proliferation Assay

[0712] MV4-11 cell line (MV-4-11, CRL-9591™) was obtained from American Type Culture Collection (ATCC). Cells were grown in a T-75 flask in RPMI Medium (GIBCO, Catalog No. 11875-093) containing 10% fetal bovine serum (ATCC, Catalog No. 30-2020) and penicillin-streptomycin (ATCC, Catalog No. 30-2300) at 37° C. in a humidified, 5% CO.sub.2 incubator.

[0713] 50 μL of cells (10,000 cells/well) were plated in a 96-well plate and incubated overnight at 37° C. in a humidified, 5% CO.sub.2 incubator. The next day, 50 μL of medium containing 3-fold serially diluted compounds in duplicate was added to the wells such that the starting concentration of the compound in the first pair of the wells was 10 μM. After 72 hour incubation with the compound, cell viability was measured in a luminometer after the addition of 100 μL/well CellTiterGlo reagent (Promega) as recommended by the manufacturer. The IC.sub.50 values for the compounds were calculated using SoftMax software.

[0714] C. Anti-Proliferative Activity

[0715] As the data in Table 1A shows, compounds 1, 2, 3a, 4a and 5 demonstrate potent anti-proliferative activity with IC.sub.50 values of 0.10 to 1.05 μM against two AML cancer cell lines, THP-1 and MV4-11.

Cell Lines and Culture:

[0719] The MOLT4 cell line (CRL-1582™) and K562 cell line (CCL-243™) were obtained from American Type Culture Collection (ATCC). They were grown in a T-75 flask in RPMI Medium (GIBCO, Catalog No. 11875-093) containing 10% fetal bovine serum (ATCC, Catalog No. 30-2020) and penicillin-streptomycin (ATCC, Catalog No. 30-2300) at 37° C. in a humidified, 5% CO.sub.2 incubator. The HL60 cell line (CCL-240™) was obtained from American Type Culture Collection (ATCC). They were grown in a T-75 flask in DMEM Medium (GIBCO, Catalog No. 11965-092) containing 20% fetal bovine serum (ATCC, Catalog No. 30-2020) and penicillin-streptomycin (ATCC, Catalog No. 30-2300) at 37° C. in a humidified, 5% CO.sub.2 incubator.

Proliferation Assay:

[0720] 50 μL of cells (8,500 cells/well) were plated in a 96-well plate and incubated overnight at 37° C. in a humidified, 5% CO.sub.2 incubator. The next day, 50 μL of medium containing 3-fold serially diluted compounds in duplicate was added to the wells such that the starting concentration of the compound in the first pair of the wells was 10 μM. After 72 hour incubation with the compound, cell viability was measured in a luminometer after the addition of 100 μL/well CellTiterGlo reagent (Promega) as recommended by the manufacturer. The IC.sub.50 values for the compounds were calculated using SoftMax software.

[0721] D-2. Anti-Proliferative Activity of Compounds in KG-1, KU812 and MEG-01 Cell Lines

[0722] Compounds were tested in the following cell lines: KG-1 acute myelogenous leukemis ATCC CCL-246, KU812 Human chronic myelogenous leukemia (CML) ATCC CRL-2099, and MEG-01 Human chronic myelogenous leukemis (CML) ATCC CRL-2021 according to the following conditions and procedures:

Growth medium: RPMI Medium 1640 Gibco #11875-093

Supplements: Fetal Bovine Serum (FBS) Gibco #10437-028

[0723] Complete cell culture medium was prepared by adding 50 mL FBS (final concentration 10%) to each 500 mL bottle of RPMI Medium 1640 (RPMI). Medium was allowed to equilibrate to 37C in a water bath before use.

[0724] One millimeter volumes of 2× the initial concentration (20 μM or 100 μM) in complete cell culture medium were prepared for each compound to be tested. 50 μl was added, in triplicate, to lane 2 wells of a 96-well plate and to lane 3 wells containing 50 μl complete cell culture medium as diluent. Two-fold serial dilutions of compounds were continued in lanes 4-10 with 50 μl final volumes. 50 μl medium without compound was added to lane 11, and 100 μl medium was added to lanes 1, 12 and rows A,H in order to prevent or minimize a thermal gradient from forming in the experimental wells.

[0725] Cells grown to 1-4×10.sup.5/mL were centrifuged, re-suspended in fresh medium at 2×10.sup.5/mL and 50 μl (10,000 cells) was added to each well containing compound (lanes 2-10) and to 6 wells (lane 11) containing medium only. Addition of cells resulted in dilution of compound to the intended 1× concentrations.

[0726] Plates were incubated at 37 C. in 5% CO.sub.2 for 72 hours.

[0727] After 72 hours incubation, plates were allowed to equilibrate to room temperature for 30 minutes and assayed for cell proliferation using the Promega CellTiter-Glo Kit (Promega #G7572) which indirectly measures ATP. 100 μl of CellTiter-Glo substrate reconstituted with CellTiter-Glo buffer was added to each well containing cells as well as 6 wells containing medium only. Plates were incubated at room temperature, protected from light, for 10 minutes to allow luminescence signal to stabilize. Luminescence was read and recorded in a LUMIstar OPTIMA luminescence microplate reader using MARS Data Analysis Software (BMG LABTECH).

[0728] The luminescence values for compound-containing wells (in triplicate) were plotted as the mean % no-compound control vs concentration using Prism GraphPad. IC.sub.50s, the concentration at which a compound reduced growth (as measured by ATP) by 50%, were obtained from the graphs.

[0730] E. Antiproliferative Activity Against 15 AML Ex-Vivo Bone Marrow Sample

[0731] Antiproliferative activity of Compound 3a and cytarabine was measured against 15 AML ex-vivo bone marrow samples (including two cytarabine-resistant samples). The assay used was Vivia's Native Environment cell depletion assay. An outline of the study is below: [0732] Five different concentrations of each drug was used as a monotherapy [0733] The incubation time point for measurement was 48 hours post drug exposure
The results are shown graphically in FIG. 6. Compound 3a provided potent ex vivo activity against the tumor cells from frozen bone marrow of the AML patients. The activity of Compound C.sub.3a was better that cytarabine with stronger potency and higher efficacy. According to the activity profile observed, Compound 3a had a mean EC50 value of 170 nM.

[0734] F. MV4-11 Xenografts

[0735] The in vivo anti-tumor efficacy of Compounds 3a, 4a and 5 in the subcutaneous MV4-11 leukemia model in CB17 SCID mice was tested.

Cell Culture:

[0736] The MV4-11 cells (ATCC-CRL-9591) were maintained in vitro as a suspension culture at a density of 0.2-1.5×106 cells/ml in RPMI1640 medium supplemented with 10% heat inactivated fetal bovine serum, 100 U/ml penicillin and 100 μg/ml streptomycin at 37° C. in an atmosphere of 5% CO.sub.2 in air. The tumor cells were routinely subcultured twice weekly. The cells growing in an exponential growth phase were harvested and counted for tumor inoculation.

Animals:

[0737] CB17 SCID, female, 6-8 weeks, weighing approximately 18-22 g.

Tumor Inoculation:

[0738] Each mouse was inoculated subcutaneously at the right flank with MV4-11 tumor cells (10×10.sup.6) in 0.2 ml of PBS (with Matrigel 1:1) for tumor development. The animals were randomized and treatment was started when the average tumor volume reached approximately 150-200 mm.sup.3 for the efficacy study. The test article administration and the animal numbers in each group are shown below.

Endpoints:

[0739] The major endpoint monitored was tumor growth delay or cure. Tumor sizes were measured twice weekly in two dimensions using a caliper, and the volume expressed in mm.sup.3 using the formula: V=0.5 a×b.sup.2 where a and b are the long and short diameters of the tumor, respectively. The tumor sizes were then used for the calculations of both T-C and T/C values. T-C is calculated with T as the median time (in days) required for the treatment group tumors to reach a predetermined size (e.g., 1,000 mm.sup.3), and C is the median time (in days) for the control group tumors to reach the same size. The T/C value (in percent) is an indication of antitumor effectiveness, T and C are the mean volume of the treated and control groups, respectively, on a given day.

[0740] TGI was calculated for each group using the formula: TGI (%)=[1−(Ti−T0)/(Vi−V0)]×100; Ti is the average tumor volume of a treatment group on a given day, T0 is the average tumor volume of the treatment group on the first day of treatment, Vi is the average tumor volume of the vehicle control group on the same day with Ti, and V0 is the average tumor volume of the vehicle group on the first day of treatment.

[0741] The results of Tumor Volume versus Time and Body Weight versus Days after Start of Treatment are shown in FIGS. 7A-7F. As can be see in FIG. 7, all animals treated with Compound 3a achieved ≥70% tumor shrinkage. Cytarabine (standard of care) and tigecycline dosed at maximum tolerated does (MTD) only demonstrated modest effect-no tumor response in either group.

[0742] G. Effect of Compound 3a on Rat Heart Mitochondrial Protein Synthesis

[0743] The effect of Compound 3a on mitochondrial protein synthesis was determined using an intact isolated rat heart mitochondrial protein synthesis assay previously described [See, 1, 2 below]. Intact, highly coupled mitochondria isolated from normal rat hearts were incubated in an incubation medium containing [S.sup.35]-methionine. The compounds were diluted to generate a final dose-response curve from 0.15 to 40 μM. The rate of incorporation of [S.sup.35]-methionine into protein was measured at 20, 40, and 60 minutes of incubation for each sample using a filter paper disc assay and expressed as pmol methionine incorporated per mg mitochondrial protein as described [1, 2, 3 below]. The time course data for control and all drug concentrations were nearly linear. The slope of each time-course data plot is calculated as the least squares best fit line through zero and the three time points for each sample. The rate of protein synthesis varies modestly with each mitochondrial preparation (mean and SEM=20.3+/−2.4 pm/mg protein). To normalize for this variability, the rates were expressed as a percent of the rate of the control line for each preparation of mitochondria.

[0744] Each experiment was repeated three times.

[0745] Dose-response curves were obtained by expressing the percent of control obtained for each concentration of Compound 3a against the concentration of Compound 3a. The dose-response curves for all three experiments were plotted together and fit using the equation y=ab/(b+x) (Sigma Plot 10.0) and the half-maximal inhibitory concentration (IC.sub.50) is reported for each drug.

Summary of Results:

[0746] FIG. 8 shows the dose-response results for Compound 3a. The dose-response curve IC.sub.50 was 0.7 μM. As such the data represents both the ability of Compound 3a to cross the mitochondrial membranes and to inhibit mitochondrial translation. [0747] 1. McKee, E. E., Ferguson, M., Bentlye, At.

Example 4: Antibacterial Activity

[1168] The antibacterial activities for the compounds of the invention were studied according to the following protocols.

Minimum Inhibitory Concentration (MIC) Assay

[1169] MICs were determined according to the Clinical and Laboratory Standards Institute (CLSI) guidances (e.g., CLSI. Performance standards for antimicrobial susceptibility testing; nineteenth information supplement. CLSI document M100-S19, CLSI, 940 West Valley Road, Suite 1400, Wayne, Pa. 19087-1898, USA, 2009). Briefly, frozen bacterial strains were thawed and subcultured onto Mueller Hinton Broth (MHB) or other appropriate media (Streptococcus requires blood and Haemophilus requires hemin and NAD). Following incubation overnight, the strains were subcultured onto Mueller Hinton Agar and again incubated overnight. Colonies were observed for appropriate colony morphology and lack of contamination. Isolated colonies were selected to prepare a starting inoculum equivalent to a 0.5 McFarland standard. The starting inoculum was diluted 1:125 (this is the working inoculum) using MHB for further use. Test compounds were prepared by dilution in sterile water to a final concentration of 5.128 mg/mL. Antibiotics (stored frozen, thawed and used within 3 hours of thawing) and compounds were further diluted to the desired working concentrations.

[1170] The assays were run as follows. Fifty μL of MHB was added to wells 2-12 of a 96-well plate. One hundred μL of appropriately diluted antibiotics was added to well 1. Fifty μL of antibiotics was removed from well 1 and added to well 2 and the contents of well 2 mixed by pipetting up and down five times. Fifty μL of the mixture in well 2 was removed and added to well 3 and mixed as above. Serial dilutions were continued in the same manner through well 12. Fifty μL was removed from well 12 so that all contained 50 μL. Fifty μL of the working inoculum was then added to all test wells. A growth control well was prepared by adding 50 μL of working inoculum and 50 μL of MHB to an empty well. The plates were then incubated at 37° C. overnight, removed from the incubator and each well was read on a plate reading mirror. The lowest concentration (MIC) of test compound that inhibited the growth of the bacteria was recorded.

[1172] Protocol for Determining Inoculum Concentration (Viable Count) Fifty 50 μl of the inoculum was pipetted into well 1. Ninety μl of sterile 0.9% NaCl was pipetted into wells 2-6 of a 96-well microtiter plate. Ten μL from was removed from well 1 and added it to well 2 followed by mixing. Ten μL was removed from well two and mixed with the contents of well 3 and so on creating serial dilutions through well 6. Ten μL was removed from each well and spotted onto an appropriate agar plate. The plate was placed into an incubator overnight. The colonies in spots that contain distinct colonies were counted. Viable count was calculated by multiplying the number of colonies by the dilution factor.
