EXAMPLE 1
Obtaining Complementary Derivatives of RNA Oligonucleotides (MATR)
[0059] The original 3-UUGGG-5 sequence is synthesized in a classical way using polynucleotide synthesizers and amplified using a polymerase chain reaction in a modification using RNA-RNA polymerase, which is obvious to a person skilled in the art.
[0060] To obtain a complementary RNA oligonucleotide, simultaneous combinatorial synthesis was used with two reagents: succinic anhydride and formic acid.
[0061] 10 mM 3-UUGGG-5 is dissolved in 1 ml of dioxane, 20 mM succinic anhydride and 20 mM formic acid are added, the solution is stirred and heated at 30-100 0 C. for 1-60 minutes. The solution was poured into ampoules and lyophilized to remove the solvent and unreacted formic acid. A combinatorial mixture is used in the study of anticancer activity.
[0062] One source molecule 3-UUGGG-5 contains 5 modifiable alcoholic ribose residues and three exocyclic amino groups of guanosinea total of 8 available groups. Incomplete combinatorial modification with only one modifiereither succinic anhydride or formic acid will yield a combinatorial mixture of 255 derivatives with different degrees of substitution in different positions. The introduction of a second modifier increases the number of derivatives of one oligonucleotide to 380 at the output.
[0063] Instead of the 3-UUGGG-5 sequence, the 3-UUCCC-5 sequence or either the 3-UUAAA-5 sequence or any sequence as the starting RNA oligonucleotide of the following nucleotide sequence can be used: 3-UUN1N2N3-5; where N1N2N3 correspond to at least one of the following sequences, including a mixture thereof: UUC; UUA; UUG; CUU; CUC; CUA; CUG; AUU; AUC; AUA; AUG; GUU GUC; GUA GUG; UCU; UCC; UCA; UCG; CCU; CCA; CCG; ACU ACC ACA ACG; GCU; GCC; GCA; GCG; UAU; UAC UAA; UAG; GAU; CAC GAA; GAG; AAU; AAC; AAG; GAU; GAC GAA; GAG; UGU; UGC; UGA UGG; CGU; CGC; CGA; CGG; AGU; AGC; AGA; AGG; GGU; GGC; GGA
[0064] These sequences are recognition triplets of nucleotides in tRNA for each of the known amino acids. A complementary blockade of such/such triplets in the cell will lead to the loss of tRNA ability to attach to the polyribosome and, accordingly, to the loss of protein synthesis.
[0065] Calculations of the number of moles of the modifier are carried out according to the combinatorics formulas: m=4(32.sup.n11); k=n(2.sup.n1), where m is the number of different derivatives of molecules in the combinatorial mixture; n is the number of groups (and moles) available for modification in the oligonucleotide structure (for example, for 3-UUGGG-5 n=3 guanosine amino groups and 5 hydroxyl groups in the ribose structure, total n=8); k is the number of moles of each modifier modifier (for example, for only one 3-UUGGG-5 m=764 modifier; k=2040, and the molar ratio is 1: 2.67). Thus, having only one oligonucleotide 3-UUGGG-5after its modification, we obtain 764 combinatorial complementary derivatives with varying degrees of affinity and hybridizability with the original molecule.
[0066] As the result combinatorial mixture (conventional name MATR) is used to study anticancer activity and stimulate tissue regeneration in local application. Derivatives of other oligonucleotides from the above list have pesticidal, herbicidal and acaricidal activities.
[0067] Modifierssuccinic anhydride or formic acid can be administered either simultaneously or sequentiallyor first inject succinic anhydride, warm the mixture for 30-100 0 C. for 1-60 minutes, and then inject formic acid and also warm the mixture for another 30-100 0 C. 1-60 minutes.
[0068]
[0069] This indicates the completion of the acylation and formylation reaction in the structure of the oligonucleotide. The chromatograms also lack peaks of other derivatives, which excludes the hydrolysis of the oligomer to monomeric fragments or the discovery of the adenine purine heterocycle. The same way in this reaction, maleic anhydride, aconitic anhydride, glutaric, phthalic anhydride and acetic anhydride can be used as one of the modifiers instead of succinic anhydride.
[0070] The same way in this reaction, formic acid ethyl ester, monochloroacetic acid, propiolactone, ethylene oxide and other low molecular weight alkylating agents (methyl chloride, ethyl chloride, propyl chloride) can be used as one of the modifiers.
[0071] In a similar fashion derivatives of 3-UUGGG-5 with different ratios of modifiers (succinic anhydride and formic acid) were synthesized and their biological activity was screened for three types of cancer: Lewis carcinoma (CL), Ehrlich ascites cancer (ARE) and HeLa-2 (CL) in vitro.
[0072] Table 1 shows the results of biological screening of derivatives.
[0073] The calculations were performed using the kumayashi blue mortal dye, the percentage of cell death was determined spectrophotometrically by staining of dead cells against the controls (living culture and completely dead). The accuracy of the spectrophotometer is 3%. The results were processed using the chi-square method for n=5 (5 wells in a plate). The statistical hypothesis of a significant difference in the efficiency of the structure with the maximum number of different derivatives (No. 17 or MATP) from other derivatives obtained empirically was confirmed (P0.05).

As can be seen from table 1, only one derivative No. 17 (MATR) showed an anticancer effect at the level of 95-100% cytotoxic effect on all three types of cancer cell cultures, while other molar ratios of reagents, incl. mono-modified derivative did not possess sufficient cytotoxic activity against cancer cells.

Synthesis of Succinylated Adenine (Control of Succinylation Reaction)
[0074] The 10 mM adenine, 10 mM succinic anhydride are dissolved in 1 ml of dioxane and heated under reflux for 1-60 minutes. Then a vacuum pump is attached to the flask and dioxane is distilled off. The precipitate was recrystallized from dioxane: glacial acetic acid. m.p=163-165 0 C. The spectrum completely confirms the structure of succinyladenine. At the same time, instead of succinic anhydride the maleic anhydride, aconitic anhydride, glutaric, phthalic anhydride and acetic anhydride can be used.

EXAMPLE 4
Anticancer Activity of MATR
[0079] Determination of the anticancer activity of MATR in the cell culture was performed in a HeLa-2 cell culture. The different amount of MATR from 2 to 12 g/ml of medium was added to medium 199. (see table 1). For the control a culture was without MATR. Cell cultures were monitored for 5 days with daily viewing. The minimum active dose (MAD) of MATR was considered to be its minimum amount, which caused degeneration of 90-95% of the cells (Table 2)

[0080] As can be seen from table 3, the efficient dose of MATR is in the range between 8-12 g/ml of solution. MATR led to 95% degeneration of tumor cells. To confirm the in vivo antitumor effect, MATR was studied on a model of Ehrlich ascites adenocarcinoma.
EXAMPLE 5
The Study of the Antitumor Effect of MATR on Ascitic Erlich Tumor Adenocarcinoma
[0081] The antitumor effect of the compositions was studied on Ehrlich ascites carcinoma models in young non-bred mice of both sexes weighing 15-17 g (68 pieces), which were kept on the diet as per vivarium protocol. The 45 mice being inoculated in the liver ascitic fluid from mouse with adenocarcinoma by using insulin syringe 0.1 ml. After 7 days, 42 mice showed signs of a tumor (increased body weight and size of the abdomen), 2 mice died on the second day, 1 mouse showed no signs of a tumor. MATR was injected into ten mice (see Table 4). Additionally, MATR was injected into another 10 mice, and 0.9% sodium chloride solution was injected to ten more mice.

Mean value (Days) Composition Investigational animals Control Animals MATR 47.41.3 3.00.5 Taxotere 151.0 30.5 Note: n = 10, p 0.05.
[0082] MATR was administered to those mice in which blood was drawn originally. Mice with Ehrlich adenocarcinoma after tumor inoculation and treatment by MATR lived 47 days, which is 12 times longer than in the control. With a reliability of more than 99.5%, a significant increase in the anti-cancer activity of MATR against control, taxotere, can be stated. After animal anatomy, it was found that, on average, the number of metastases was 70% less in animals treated with MATR and the average weight of metastases was 20% of the control (taxotere).
EXAMPLE 6
Antitumor Activity of MATR on the Example of Shvets Leukemia
[0083] The compositions (MATR and Taxotere) were administered intraperitoneally three times with an interval of two hours in 0.5 ml. For MATR injection aqueous solution was used. The total doses of the compositions were 34.0, 68.0, 84.0, 102.0 and 136 mg/kg. The number of dead animals in each group was confirmed every 24-48 hours. The calculation of the toxic dose, LD50, was carried out according to the protocol. The lethal dose, LD.sub.1000, was determined experimentally.
[0084] As a result of the experiments, it was found that for the MATR compound LD50=3100 g/kg, LD100=4200 g/kg. From a comparison of these values, it follows that the toxicity of the aqueous MATR is significantly lower than that of the taxotere control compound (120 mg/kg).
[0085] According to histological studies, the death of animals receiving toxic doses of drugs is due to enterotoxicity. There is a pronounced dysplasia of epithelial cells in the intestine, a violation of its regenerative function, a reduction in the number of mitoses. Minor changes were noted in the kidneys: small swelling of the stroma, granular dystrophy of the tubules, small focal hemorrhages.
[0086] The antitumor activity of MATR was evaluated from experiments conducted on five groups of animals (10 animals in each group). Outbred white rats weighing 150-200 g under the thigh skin were transplanted 2. 10821010 cells of the inoculating strain of Schwez leukemia. Animals of group 1 served as a control, group II received taxotere, IIItaxotere+MATR, IVMATR in solution, VMATR in suspension with TWIN-80. The drugs were administered intraperitoneal three times on 4-6 days after tumor transplantation, i.e. during the period of the logarithmic phase of its growth, the second and third timeswith intervals of 24-48 hours, respectively. The total dose of drugs was 27.3 mg/kg per pure drug.
[0087] Antitumor activity was evaluated by the following physiological parameters:
[0088] by tumor volume, v (cm.sup.3);
[0089] by the degree of inhibition of tumor growth (T/C, %);
[0090] survival of animals on the 10th day (SA, %);
[0091] the life expectancy of animals (LEA, days).
[0092] The calculations were performed according to the following formulas:
where m 1, m 2, m 3 are three mutually perpendicular measurements of the tumor node;
-
where V.sub.contr and Vexptumor volume in the control and experimental groups, respectively:
[0093] Where A is the number of animals on the 10th day after tumor transplantation,
[0094] N is the number of animals in this group.
[0095] The life expectancy of animals was determined by the number of days elapsed from the moment of tumor inoculation to the death of the last animal in this group. Data on the biological activity of MATR given in table 5.
[0096] The analysis of the data presented in table 5 shows that the MATR preparation in its pure form (suspension), compared with the control, inhibits tumor growth by 94%. Its use allows to obtain 100% survival of animals. MATR aqueous solution inhibits tumor growth by 95%, provides 100% survival of animals.
[0097] At the same time, their life expectancy is increased by 7-8 days compared to control.
[0098] A comparative analysis of the data given in the table allows us to conclude that the claimed compound, MATR in suspension, is more toxic than the preparation MATR in the aqueous solution. In terms of antitumor activity and survival, it is not inferior to the MATR compound in a true solution, but in terms of such an indicator as life expectancy, it significantly exceeds it, since it doubles life expectancy.
TABLE-US-00005 TABLE 5 Anticancer efficacy of MATR in different forms-aqueous solution and concentrated suspension Group of animals 2 3 4 1 (MATR (MATR (mixture 5 Name of (the sus- aqueous of taxotere (taxotere indicators control) pension) solution) and MATR) only) The injected 9.1*3 = 27.3 dose, mg/kg Toxic dose, 3100 1500 130 120 LD.sub.50, mcg/kg Lethal dose, 4200 2700 180 180 LD.sub.100, mcg/kg Tumor volume, 15.0 0.75 1.00 0.05 0.60 0.75 0.03 0.73 cm3 0.03 0.03 The degree of 0 94 95 tumor growth inhibition, T/C.,% Survival, % 0 100 Life 14.6 0.5 11.6 1.0 21.0 1.0 expectancy, days
[0099] Therefore, discovering MATR led to the production of a substance more effective than the known antitumor drugs, since the proposed drug is superior to or comparable with known substances in terms of physiological activity characterizing its antitumor effect and compares favorably with them due to the reduction of toxicity.
[0100] A number of new properties of MATR were revealed: a high degree of inhibition of tumor growth, significant survival of animals and an increase in their life expectancy while reducing toxicity, which suggests its promise for creating drugs effective in the treatment of malignant tumors.
EXAMPLE 7
Wound Healing Activity
[0101] Determination of the effect of the compositions MATR (combinatorial derivative of 3-UUGGG-5) (D1) and MATR2 (combinatorial derivative of 3-UUGAA-5) (D2) on tissue regeneration.
[0102] The study of the wound healing properties of the compositions was carried out on male Vistar white rats. In 38 animals that were anesthetized with diethyl ether for 2-4 min., A 2 by 2 cm skin area was cut out on the dorsal side of the body, behind the right shoulder blade. The skin was taken with tweezers, it was pulled back, the skin fragment was cut 2 cm in size, wound depth 2 mm, the average area of the wound was 41.0 cm.sup.2.
[0103] The resulting wounds of a polygonal shape were intensively bleeding. Then the wounds of animals first and second groups (10 in each), D1 and D2 compositions were applied.
[0104] The wounds of rats of the 3rd group were treated with Dexpanthenol (DP), the 4th group of 8 animals was the control group, the wounds of these animals were not treated. The compositions in contact with blood formed a gel form, it was covering entire surface of the wound and capture a small fragment of surrounding skin around the wound.
[0105] The glue BF-6 was applied on top of the gel, dried and the animals were released into cells. The planimetric studies of the wounds were carried out from 1.sup.st day of experiment on the 3rd, 6.sup.th, 9.sup.th, 11.sup.th, and 13.sup.th days, which made it possible to judge the features of reparative processes.
[0106] The measurement of the area of the wounds was carried out as follows: on the celluloid film which was covering the wound entirely, contours were applied, after which the area of the wound surface was determined using graph paper.
[0107] Stimulation of the growth of pluripotent hematopoietic cells CD34+
[0108] The drugs were studied in an experiment on a model of cytostatic hemo-immunosuppression.
[0109] The experiments were performed on 90 male Wistar rats weighing 160-200 g. Animals were kept with free access to water and food. Two experimental and control groups comprised 30 animals each. In both groups, hemo-immunosuppression was induced five times, at 24-hour intervals, by intraperitoneal administration of cyclophosphamide at a dose of 10 mg/kg, rubomycin 2 mm/kg, and prednisone 2 mg/kg in 3 ml of normal saline.
[0110] On the next day after the end of the administration of hemoimmunosuppressive drugs, the animals of the experimental group were smeared the skin at the withers with one of the gels in an amount of 0.5 g/animal and BF6 glue was applied. The gel was changed every other day. Animals of the control group at the same time were followed same protocol but applied to the skin with a placebocarbopol gel without active substances. The effect of the drug was evaluated based on blood test results on 1,10,30,60,90 days of the experiment.
[0111] The proliferative activity of CD34+ stem cells was studied using the CD34 Count kit [2] for cytofluorimetry using a FACS Calibur flow cytofluorimeter. Digital material was processed using nonparametric statistics with the definition of the criterion U according to Wilcoxon-Mann-Whitney.
[0112] The results of the first series of experiments on the study of wound healing properties (Table 6) showed that wound healing at all stages of the study was significantly accelerated under the influence of compositions D1 and D2. The effectiveness of composition D1 was statistically higher than that of composition D2 and DP.

[0114] The introduction of cytotoxic drugs led to a decrease in the level of CD34 at the time of initiation of therapy by 3-4 times, compared with the initial level. Moreover, the animals of both groups were able to restore them to normal values. However, bone marrow regeneration processes with the restoration of peripheral blood indices proceeded in different ways.
[0115] Local application of samples of D1 and D2 to the skin of rats accelerated these processes by about 2 times, as evidenced by the excess of blood parameters of animals of the experimental group by 30 days more than 2 times, while these indicators in animals of the control group came to normal values only on the 60th day.
[0116] The increase in the number of pluripotent cells, which correlated with the acceleration of wound regeneration, indicates a predominant stimulation of stem cell division at the periphery, rather than an increase in bone marrow functions. The maximum effect from the use of D1/D2 was observed on the 60th day, and the restoration of the physiological level of pluripotent cells was observed already on the 10th day after the start of application of the gel. Due to the fact that the gel was applied to intact skin, we can talk about the high resorptive properties of the gel and its general effect on the whole body.
[0117] Therefore, the action of D1/D2 leads to selective stimulation of division of pluripotent cells in the wound and stimulation of excretion of fibroblast growth factors, contribute to a 6-fold acceleration of restoration of animal immunity after induced immunodeficiency.
[0118] Also, variants of the compositions in the form of gel D1 and D2 have a significant regenerative ability to wounds, accelerating epithelization and wound healing on average twice.
[0119] Gels D1 and D2 have the ability to be absorbed through the skin and have a beneficial effect on the immune system of the whole organism through stimulation of the division of pluripotent cells CD34.

Acaricidal Activity
[0120] Ovicidal test on a spider mite (Tetranychus urticae) by immersion using a combinatorial mixture of MATR based on oligonucleotide 3-UU UAA-5.
[0121] Four adult female spider mites (Tetranychus urticae), which are a sensitive species, were placed on each 15 mm leaf disc cut from young leaves. After laying the eggs for 24 hours at 26-28 C., the females were removed and the eggs laid on the discs were calculated.
[0122] The treatment was carried out by immersing the disks in solutions containing the corresponding concentration of active compounds (using DMSO as a co-solvent in an amount of no more than 5% in the test solution). The dive lasted 5 s.
[0123] After processing, the disks were dried on dry filter paper, then stored on wet filter paper at 26-28 C. in a Petri dish until they were removed from untreated control eggs, and then the excretion coefficient was determined. Each experiment was repeated four times using at least three similar experiments for each concentration.
[0124] The values of efficacy given for each concentration show the average value of treatments carried out on at least 250 tick eggs. Corrected mortality was calculated according to Abbott. The results expressed in percentages, are shown in table. 8.

[0125] As can be seen from the table, the processing of the MATR solution with samples, leads to a significant decrease in the survival rate, which indicates the presence of acaricidal action of the combinatorial MATR library based on 3-UUUAA-5 oligonucleotide
EXAMPLE 9
Herbicidal Activity
[0126] Plastic trays were lined with plastic wrap and filled with pasteurized sandy loamy soil Sassafras (pH 6.5, 1% O.M.). One tray was seeded with wheat (Triticum acstivum), barley (Hordeum vulgare), wild oats (Avena fatua), roofing bonfire (Bromus Secalinus), leaf-tailed mouse-tail (Alopecurus myosurocdes), bluegrass annual (Poa annua), Italian bristle, setaria by tares (Liolium multiflorum), and rapeseed (Brassica napus).
[0127] The second tray was inoculated with the following plants: Matricaria inodora, tenure (Gallum aparine), Russian solyanka (Salsola kali), shepherd's purse (Capsella bursapastoria), cochia (Cochia scoparia), black nightshade (Solarium. Nigrum), veronica (Veronica persica), highlander climbing (Polyconum convolvulus) and sugar beet (Beta vulgaris). For post-emergence treatment, the first tray or tray was seeded 14 days before spraying, and the second tray was planted 24 days before treatment.
[0128] Plants after post-emergence treatments were classified by height from 1 to 15 cm, depending on the species. Wheat, barley and oatmeal were in the developmental stage of 2 leaves (Stage II Ladors). Before spraying for pre-emergence treatments, another set of trays was prepared identically. Herbicides were diluted in a non-phytotoxic solvent and applied to trays using a belt sprayer.
[0129] Additionally, three other species were evaluated: Veronica hederae folla, starfish (Stellaria media) and Viola arveusis. These plants were grown in five-inch pots containing the same soil as previously described. Plants were grown for 22 days prior to treatment. The application of the herbicide was carried out in the same way as when screening trays. Plants were grown in a greenhouse for 21 days, during which time a visual assessment was made when compared with the untreated control. The assessment was based on a scale from 0no effect to 100complete death. The results are shown in table. 9-11.

EXAMPLE 11
Pharmaceutical Compositions
[0142] Various methods of administering supramolecular combinatorial derivatives of RNA oligonucleotides (MATR) can be used. The MATR composition can be given orally or can be administered by intravascular, subcutaneous, intraperitoneal injection, in the form of an aerosol, by ocular route of administration, into the bladder, topically, and so on. For example, inhalation methods are well known in the art.
[0143] The dose of the therapeutic composition will vary widely depending on the particular administered MATR, the nature of the disease (purpose), frequency of administration, route of administration, clearance of the agent used from the host, and the like. The initial dose may be higher with subsequent lower maintenance doses. The dose can be administered with a frequency of once a week or once every two weeks, or divided into smaller doses and administered once or several times a day, twice a week, and so on to maintain an effective dose level.
[0144] In many cases, oral administration would require a higher dose than intravenous administration. The compounds of this invention may be included in a variety of compositions for therapeutic administration.
[0145] More specifically, the compounds of the present invention can be incorporated into pharmaceutical compositions in combination with suitable pharmaceutically acceptable carriers or diluents and can be incorporated into preparations in solid, semi-solid, liquid or gaseous forms, such as capsules, powders, granules, ointments, creams, foams, solutions, suppositories, injections, forms for inhalation use, gels, microspheres, lotions and aerosols.
[0146] Therefore, the administration of the compounds can be carried out in various ways, including oral, buccal, rectal, parenteral, intraperitoneal, intradermal, percutaneous, intratracheal administration and so on.
[0147] The MATR can be distributed systemically after administration, or can be localized using an implant or other composition that holds the active dose at the site of implantation. The compounds of the present invention can be administered alone, in combination with each other, or they can be used in combination with other known compounds (for example, classic anti-cancer agents, anti-inflammatory agents, immunomodulators and so on).
[0148] In pharmaceutical dosage forms, the compounds may be administered in the form of their pharmaceutically acceptable salts. The following methods and excipients are given by way of example only and are not in any way limiting.
[0149] For oral administration, the compounds can be used alone or in combination with suitable additives for the manufacture of tablets, powders, granules or capsules, for example, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binding agents, such as crystalline cellulose, cellulose derivatives, gum arabic, corn starch or gelatins; with disintegrants such as corn starch, potato starch or sodium carboxymethyl cellulose; with mazyvayuschimi agents such as talc or magnesium stearate, and, if desired, with diluents, buffering agents, moistening agents, preservatives and flavoring agents.
[0150] The compounds can be incorporated into injectable compositions by dissolving, suspending or emulsifying them in an aqueous or non-aqueous 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, emulsifiers, stabilizers and preservatives. The compounds may be used in an aerosol composition for inhalation administration.
[0151] The compounds of the present invention can be incorporated into suitable pressure propellants such as dichlorodifluoromethane, propane, nitrogen and the like. In addition, the compounds can be incorporated into suppositories by mixing with a variety of bases, such as emulsifying bases or water-soluble bases. The compounds of the present invention can be administered rectally using a suppository.
[0152] A suppository may contain excipients, such as cocoa butter, carboax, and polyethylene glycols, which melt at body temperature but are solid at room temperature. Standard dosage forms for oral or rectal administration, such as syrups, elixirs and suspensions, where each unit dose, for example, a teaspoon, tablespoon, tablet or suppository, may contain a predetermined amount of a composition containing one or more compounds of the present invention.
[0153] Similarly, unit dosage forms for injection or intravenous administration may contain the compound of the present invention in the composition in the form of a solution in sterile water, normal saline, or another pharmaceutically acceptable carrier. Implants for sustained release of compositions are well known in the art. Implants are made in the form of microspheres, plates, and so on with biodegradable or non-biodegradable polymers.
[0154] For example, polymers of lactic and/or glycolic acid form a degradable polymer that is well tolerated by the host. An implant containing the anti-cancer MATP of the invention is positioned close to the tumor, so that the local concentration of the active agent is increased compared to other areas of the body.
[0155] As used herein, the term unit dosage form it refers to physically discrete units suitable for use as single doses for human and animal subjects, each unit containing a predetermined number of compounds of the present invention, which, according to calculations, is sufficient to provide the desired effect together with a pharmaceutically acceptable diluent, carrier or excipient.
[0156] The descriptions of the unit dosage forms of the present invention depend on the particular compound used, and the effect to be achieved, and the pharmacodynamics of the compound used in the host. Pharmaceutically acceptable excipients, such as excipients, adjuvants, carriers or diluents, are generally available. In addition, pharmaceutically acceptable excipients, such as pH adjusting agents and buffering agents, tonicity agents, stabilizers, wetting agents and the like, are generally available.
[0157] Typical doses for systemic administration range from 0.1 pg to 100 milligrams per kg of subject body weight per administration. A typical dose may be one tablet for administration from two to six times a day, or one capsule or sustained release tablet for administration once a day with a proportionally higher content of the active ingredient.
[0158] The effect of prolonged release may be due to the materials of which the capsule is made, dissolving at different pH values, capsules providing a slow release under the influence of osmotic pressure or any other known controlled release method. It will be clear to those skilled in the art that dose levels may vary depending on the particular compound, the severity of the symptoms, and the subject's predisposition to side effects. Some of the specific compounds are more potent than others.
[0159] Preferred doses of this compound can be readily determined by those skilled in the art in a variety of ways. A preferred method is to measure the physiological activity of the compound. One of the methods of interest is the use of liposomes as a vehicle for delivery.
[0160] Liposomes fuse with the cells of the target region and ensure the delivery of liposome contents into the cells. The contact of the liposomes with the cells is maintained for a time sufficient for fusion, using various methods of maintaining contact, such as isolation, binding agents and the like. In one aspect of the invention, liposomes are designed to produce an aerosol for pulmonary administration.
[0161] Liposomes can be made with purified proteins or peptides that mediate membrane fusion, such as Sendai virus or influenza virus and so on. Lipids may be any useful combination of known liposome forming lipids, including cationic or zwitterionic lipids, such as phosphatidylcholine. The remaining lipids will usually be neutral or acidic lipids, such as cholesterol, phosphatidylserine, phosphatidylglycerol and the like.
[0162] To obtain liposomes, the method described by Kato et al. (1991) J. Biol. Chem. 266: 3361. Briefly, lipids and a composition for incorporation into liposomes containing MATP are mixed in a suitable aqueous medium, suitably in a salt medium, where the total solids content will be in the range of about 110 wt. %. After vigorous stirring for short periods of approximately 5-60 seconds, the tube is placed in a warm water bath at approximately 25-40 C. and this cycle is repeated approximately 5-10 times.
[0163] The composition is then sonicated for a suitable period of time, typically approximately 1-10 seconds, and optionally further mixed with a vortex mixer. Then the volume is increased by adding an aqueous medium, usually increasing the volume by about 1-2 times, followed by agitation and cooling. The method allows to include supramolecular structures with high total molecular weight in liposomes.
[0164] Compositions with Other Active Agents p To use this methods under consideration, the MATR can be formulated with other pharmaceutically active agents, in particular other anti-cancer, immunomodulatory, wound healing, antiviral agents.
[0165] Other agents of interest include a wide range of unmodified drugs known in the art, including antibiotics. Classes of antibiotics include penicillins, for example, penicillin G, penicillin V, methicillin, oxacillin, carbenicillin, nafcillin, ampicillin and so on; penicillins in combination with betalactamase inhibitors; cephalosporins, for example, cefaclorome, cefazaliminum, cefazolemine, cefazolemine, cefazolemine, cefazolemine, monobactams; aminoglycosides; tetracyclines; macrolides; lincomycins; polymyxins; sulfonamides; quinolones; chloramphenicol; metronidazole; spectinomycin; trimethoprim; vancomycin; and so on.
[0166] Antifungal agents are also useful, including polyenes, for example, amphotericin B, nystatin, flucosin; and azoles, for example miconazole, ketoconazole, itraconazole and fluconazole. Anti-TB drugs include isoniazid, ethambutol, streptomycin and rifampin.
[0167] Other agents of interest include a wide range of antiviral derivatives of mononucleotides and other RNA polymerase inhibitor agents known in this type approach.
