Background Art Tannic acid and tannin complexes are found in the trunk of plants of the Musaceae Family, i. e., Musa Paradisiaca, Musa Cavendish Enano, and related Linnaean classifications. Members of this Family are commonly known as plantains.

Tannic acid is known to be useful in a diagnostic test for the detection of cancer. For example, Macartney et al. in J. Pathol. (ENGLAND) September 1979,129 (1) p. 13-20,"Intracellular filaments in human cancer cells : a histological study ", discloses that the distribution of intracellular filamentous systems in human breast and colon cancers has been demonstrated by means of the tannic acid-phosphomolybdic acid-milling dye staining technique. Plasma membrane-associated staining is prominent in breast carcinomas and is strongest in anaplastic tumors. Strong staining is also noted in the cells at the margins of the tumors where the malignant cells are invading the surrounding tissues. In colon carcinomas, filaments are mainly restricted to the terminal web region of the cells but dedifferentiation is accompanied by the development of circumferential staining of the cell membrane. The results are discussed in relation to immunohistochemical and electron microscopic studies of contractile proteins in non-muscle cells.

Tannic acid has been shown to inhibit 12-O-tetra-decanoyl-phorbol-13-acetate (TPA) tumor promotion. Perchellet et al., Basic Life Sci (UNITED STATES) 1992,59 p. 783-801, discloses that naturally occurring plant phenols with antimutagenic and anticarcinogenic activities were tested for their abilities to inhibit the biochemical and biological effects of the potent tumor promoter 12-O-tetradecanoyl-phorbol-13-acetate (TPA) in mouse epidermis in vivo. When applied topically to mouse skin, tannic acid (TA), ellagic acid, and several gallic acid derivatives all inhibited TPA-induced omithine decarboxylase activity, hydroperoxide production, and DNA synthesis, three biochemical markers of skin tumor promotion. In a two-step initiation-promotion protocol, the same phenolic compounds also inhibited the incidence and yield of skin tumors promoted by TPA.

Ramanathan et al. in"Cytotoxic effect of plant polyphenols and fat-soluble vitamins on malignant human cultured cells", Cancer Lett. (NETHERLANDS) Mar. 15,1992, 62 (3) p. 217-24, discloses in vitro studies which showed that several flavonoids, tannic acid, gallic acid and fat-soluble vitamins inhibited HeLa and Raji lymphoma cell growth. The inhibition trend exhibited by these

compounds was similar for both cell lines, and their growth was inhibited dose dependently. Butein, (10 microM), the most potent anti-proliferative agent, exerted 30% growth inhibition and was more effective on HeLa cells. Retinol (100 microM) inhibited cell proliferation completely. Tannic acid was twice as potent as its monomer gallic acid. From structure-activity consideration, the C 2, 3-double bond of the flavonoid molecule was important for activity. Flavonoid aglycones were more effective than their corresponding glycosides in suppressing cell growth in vitro. No in vivo results were presented.

Athar et al.,"Effect of dietary tannic acid on epidermal, lung, and forestomach polycyclic aromatic hydrocarbon metabolism and tumorigenicity in Sencar mice,"Cancer Res. (UNITED STATES) Nov. 1, 1989,49 (21) p. 5784-8, discloses tannic acid inhibits the mutagenicity of several polycyclic aromatic hydrocarbons (PAHs) and their bay-region diol-epoxides. Studies have shown that when applied topically to Sencar mice, tannic acid caused substantial inhibition of epidermal PAH metabolism, subsequent PAH-DNA adduct formation, and PAH-induced skin carcinogenesis. However, initiation and promotion of tumors are distinguishable stages of carcinogenesis, quite different from attenuation of growth of existing tumors, or remission of cancer. That is, remission of tumors and other cancer is a process unrelated to the initiation and promotion of cancer. Athar et al. addresses the rate of tumor formation in mice. These authors used a concentration of 1% tannic acid in the feed for a total dose of about of 50 mg per day for evaluation of induction of lung and forestomach tumors in mice. Tables 2 and 3 of Athar disclose a reduction of the incidence of tumors per mouse in the group treated with 1% tannic acid. Thus, Athar's work addresses the formation of tumors, but not the regression of tumors.

Athar et al. discloses a reduction in carcinogenesis in mice. Athar et al. does not disclose or suggest the use of an extract of Musaceas formulated as a pharmaceutical composition comprising tannic acid, tannin complexes, and/or gallic acid. Most importantly, Athar et al. does not disclose or suggest the effect on existing tumors or other diseases, of an extract of Musaceas containing tannic acid, tannin complexes and/or gallic acid. None of the above publications disclose that either an extract of Musaceas, tannic acid, tannin complexes, or gallic acid are useful for the treatment of existing cancer or other diseases.

Current standard cancer treatments include surgery, chemotherapy and radiation therapy, which often present patients with unpleasant side effects and, depending on the type of cancer may have limited effectiveness as treatments.

There is thus a need in the art for proven effective treatments, with limited unpleasant side effects, for many types of cancer and other diseases that may have their origins in poorly regulated cell growth. The Musaceas extract pharmaceutical composition and method of the present invention overcomes the deficiencies in the prior art compounds.

The above and other objects of the invention will become readily apparent to those of skill in the relevant art from the following detailed description and figures, wherein only the preferred embodiments of the invention are shown and described, simply by way of illustration of the best mode of carrying out the invention. As is readily recognized, the invention is capable of modifications within the skill of the relevant art without departing from the spirit and scope of the invention.

The present invention relates to pharmaceutical compositions comprising an extract of Musaceas having tannic acid, gallic acid, tannin complexes or mixtures thereof, and a method of treating cancer and other diseases with plant extracts containing tannic acid, gallic acid, and/or tannin complexes. The invention will now be described in a manner to enable production and use of the tannic acid, gallic acid, and/or tannin complex-containing compositions for the treatment of cancer and specific other diseases.

Tannin complex compositions as used herein means hydrolyzable tannins, such as esters of sugars, usually glucose.

What is known about the cancer cells'adhesion and their invasive and metastatic growth potential in human tumors ? Tumor cells produce an outer protective covering which camouflages the cancer cells epitope structure so the immune system cannot recognize the cells. The protective coating contains N-acetylneuraminic acid in a linear homopolymer of 2-8 linked N-acetylneuraminic acid (NeuNAc) which is referred to as polysialic acid (PSA). PSA is expressed on the adhesion molecule NCAM (Neural Cell Adhesion Molecule) and most cell adhesion molecules. In the cancer patient, PSA is found in extremely elevated blood levels as well as bound to erythrocytes and other blood components vital to the immune response.

It has been shown experimentally that PSA-NCAM drastically increases cell to cell distances and decreases the adhesion potential on NCAM. One of the vehicles for this physiological change is the hydrated volume of PSA in PSA-NCAM versus NCAM in adjacent cells. The presence of PSA decreases adhesion via physical impedance of overall membrane contacts. These modulatory effects of PSA are relevant to cell migration, establishment of temporal cell-cell contacts, and cellular differentiation during embryonic development.

In the cancer patient, the presence of PSA is linked to a loss of adhesion potential which facilitates the invasive and metastatic growth of the tumors as well as potential structural differentiation and reorganization of healthy cells into tumor cells, i. e. neoplastic cells.

PSA is the principal molecule involved in the masking of the tumor-specific antigens (TA) which normally binds to immune system components, decreasing the effectiveness of NCAM and other cell adhesion molecules, and inducing differentiation of healthy cells into neoplasts. Thus, if one can obtain selective removal of PSA from tissues and the bloodstream where possible, the major limitation that makes cancer difficult to cure, outside of operative conditions, would be eliminated. This would allow the body to attack and destroy a tumor in much the same way it rejects a transplanted organ.

Tannic acid, gallic acid, and tannin complexes in accordance with the present invention bind to and precipitates N-acetylneuraminic acid bound in PSA-NCAM as well as in circulating blood and bound to erythrocytes. Tannic acid recognizes the linear homopolymer of 2-8 linked N-acetylneuraminic acid, with the exposed amino group at the fifth (5) position, as an amino acid chain (protein).

The valent electrons on the nitrogen group of PSA bind covalently to the carbonyl group of tannic acid, linking the chains of the tannic acid moiety. The resulting bond is a very stable one with several resonance structures. See scheme 1 below. 0 OH OH 0 1 1 11 CH-CH-C-OH 0 7 8 9 HO 1 6 6 \Nx H N OH C O/\CHs N-Acetylneuraminic Acid ;+ r COOH HOY o OH HN O OH R N Polysialic Acid (PSA) OH HO OH 0 I H Hy Cj ! out 0 1 'O OH HO O O C OH Tannic Acid OH OH Three moles of N-acetylneuraminic acid are bound to each mole of tannic acid in solution. The binding of tannic acid and the depolymerization of PSA under mildly acidic conditions provides evidence

that the reaction between tannic acid and PSA (leading to precipitation of three moles of N-acetylneuraminic acid for every mole of tannic acid) is a highly favored and facilitated reaction.

The tannic acid, gallic acid, and tannin complexes act by stripping N-acetylneuraminic acid from the cell surface moiety. The tannic acid, therefore, acts as an astringent. In so doing, tannic acid and tannin complexes affect the cell changes discussed previously, allowing the body's own immune system to reject cancerous growth in much the same way it rejects any foreign invader.

The extract containing tannic acid, gallic acid, and tannin complexes of the present invention exposes cancer cell epitopes that were previously camouflaged by the PSA. At the same time tannic acid, gallic acid, and tannin complexes elevate the immune response by freeing the circulating blood components from bound PSA.

The predominant target of PSA in its propagation of an immune deficient condition in cancer patients is the macrophage, a cell that not only phagocytizes unfriendly cells but also activates the cell-mediated and humoral-immune response. It is believed that the cancer cell, by the secretion of N-acetylneuraminic acid and its polymerization into PSA, induces an immune deficiency that is reversed by the action of tannic acid and tannin complexes.

Method of Production of Tannic Acid Product Thus the tannic acid, gallic acid, and tannin complexes of the present invention may be formulated into a pharmaceutical composition for the treatment of cancer and other diseases. Tannic acid, gallic acid, and/or tannin complexes in accordance with the present invention may be produced by extraction of Musaceas. To obtain tannic acid, gallic acid, and/or tannin complexes from natural sources, the following procedure is followed.

To obtain the active tannic acid, gallic acid, and/or tannin complexes, the trunk of any of the plants of the Musaceae Family, for example, but not limited to Musa Paradisiaca, Musa Cavendish Enano, and related Linnaean Classifications, are milled to extract the sap of the plant. The pulp is filtered out of the sap to obtain a clear, characteristic tan liquid.

This liquid is preferably incorporated into a standard pharmaceutical preparation containing as its base : sorbitol 70% solution (about 21%), partially hydrogenated castor oil such as that sold under the trademark Cremophor RH40 (about 8. 8%), potassium sorbate (about 0. 15%), methylparaben (about 0. 038%), and propylparaben (about 0. 013%) w/w (weight to weight). The batching procedure is a United States Food and Drug Administration (FDA) approved, Current Good Manufacturing Practices (CGMP), standard operating procedure (SOP) for liquid pharmaceuticals. The total percent of tannic acid, gallic acid, or tannin complex in the final product should be about 2. 5-20 percent. Preferably the amount of tannic acid or tannin complex in the final product is about 3. 0-10 percent concentration, most preferred is about 5% tannic acid, gallic acid, and/or tannin complex based on total concentration of 100% when the active agent is in the presence of a pharmaceutical carrier.

If the natural sources yield a percentage lower than 5%, a food grade tannic acid may be used to yield a 5% concentration. If the natural source yields a higher percentage than 5%, the product may be diluted and retested to assure a 5% concentration.

To prepare tannic acid, gallic acid, and tannin complexes from a synthetic source, the following batching procedure is an FDA approved, CGMP, SOP for liquid pharmaceuticals. Food Grade Tannic Acid is dissolved into water along with the standard pharmaceutical preparation as described under the natural extract. The percent tannic acid in final product is about 5 percent (5%). Tannic acid (C76H520,8) may be produced synthetically as described in references cited in the Merck Index llth Ed. , abstract 9023, p. 1431, Merck Publishing Company 1989, (incorporated herein by reference in its entirety).

Further, the pharmaceutical compositions of the present invention are useful for systemic administration to humans and animals in unit dosage forms, such as tablets, capsules, pills, powders, granules, suppositories, sterile parenteral solutions or suspensions, sterile non-parenteral solutions or suspensions oral solutions or suspensions, oil in water or water in oil emulsions and the like, containing suitable quantities of an active ingredient.

Either fluid or solid unit dosage forms can be readily prepared for oral administration. For example, the tannic acid or tannin complex compounds of the invention can be mixed with conventional ingredients such as dicalcium phosphate, magnesium aluminum silicate, magnesium stearate, calcium sulfate, starch, talc, lactose, acacia, methyl cellulose and functionally similar materials as pharmaceutical excipients or carriers. A sustained release formulation can optionally be used. Capsules can be formulated by mixing the compound with a pharmaceutical diluent that is inert and inserting this mixture into a hard gelatin capsule having the appropriate size. If soft capsules are desired, a slurry of the compound with an acceptable vegetable, light petroleum, or other inert oil can be encapsulated by machine into a gelatin capsule.

Suspensions, syrups and elixirs can be used for oral administration of fluid unit dosage forms. A fluid preparation including oil can be used for oil soluble forms. A vegetable oil such as corn oil, peanut oil or sunflower oil, for example, together with flavoring agents, sweeteners and any preservatives produces an acceptable fluid preparation. A surfactant can be added to water to form a syrup for fluid unit dosages. Aqueous alcoholic pharmaceutical preparations may be used having an acceptable sweetener such as sugar, saccharin or a biological sweetener and a flavoring agent in the form of an elixir.

Pharmaceutical compositions for parenteral and suppository administration can also be obtained using techniques standard in the art. The tannic acid and tannin complexes can be present in the reservoir alone or in combination form with pharmaceutical carriers. The pharmaceutical carriers acceptable for the purpose of this invention are the art known carriers that do not adversely affect the drug, the host, or the material comprising the drug delivery device. Suitable pharmaceutical carriers include sterile water ; saline, dextrose ; dextrose in water or saline ; condensation products of castor oil and ethylene oxide combining about 30 to about 35 moles of ethylene oxide per mole of castor oil ; liquid acid ; lower

alkanols ; vegetable oils such as corn oil ; peanut oil, sesame oil and the like, with emulsifiers such as mono- or di-glycerides of a fatty acid, or a phosphatide, e. g., lecithin, and the like ; glycols ; polyalkylene glycols ; aqueous media in the presence of a suspending agent, for example, sodium carboxymethyl-cellulose ; sodium alginate ; poly (vinylpyrolidone) ; and the like, alone, or with suitable dispensing agents such as lecithin ; polyoxyethylene stearate ; and the like. The carrier can also contain adjuvants such as preserving, stabilizing, wetting, emulsifying agents and the like.

Additional formulations for administration can be made in accordance with methods and amounts known in the art as set forth in Remington's Pharmaceutical Sciences, 18th Ed. , Wiley Publishing (1990) incorporated herein by reference in its entirety.

Experimental Example 1. Effect of pharmaceutical composition on cell growth. Extract of Musaceas is formulated with sorbitol as a composition containing 5% tannic acid. The solution is filtered through sterile 0. 22 micron cellulose acetate membrane (Beckton-Dickenson Falcon 7111) and secondarily filtered through a 0. 2 micron low protein binding non-pyrogenic filter (Gelman Sciences). The effect of various concentrations of the pharmaceutical composition on NLF Neuroblastoma cell proliferation is shown in Table 2.

The results appear to show a substantial inhibition of tumor cell growth with increasing concentrations of the pharmaceutical composition. A subsequent measurement of quenching showed no statistically significant effect of quenching on the actual counts.

Experimental Example 2. Inhibition of neuroblastoma cell growth by Musaceas extract. The effect of extract on NFL neuroblastoma cell growth is measured at greater dilutions of extract, as shown in Table 3. The extract is powerfully biostatic to these cancer-derived cells even when diluted over 14 fold.

The anti- tumor efficacy of Musaceous extract is evaluated using the A549 human lung adenocarcinoma xenotransplantation system.

A549 cells (about 7 x 106 cells) are administered to the subcutaneous flanks of 21 6-8 week old Balb/c nulnu mice, maintained in accordance with PHS policy and AAALAC principles. The resultant tumors of the A549 cells are measured weekly and tumor volumes calculated. When tumors achieve a size of 75- 100mm3, mice are randomized into one of three groups of 7 mice each.

The pharmaceutical composition of Musaceas extract containing sorbitol is filtered sequentially through a coarse filter, a 0. 45 micron filter, and a sterile 0. 22 micron filter. Solution is diluted with vehicle to achieve working solutions with a concentration of lOmg/ml tannic acid and 2mg/ml tannic acid. The volumes of the preparation administered to mice in the experimental cohort are similar to volumes of vehicle administered to control mice. Group 1 receives 1000mg/kg body weight/day. Group 2 receives 200 mg/kg/day, and control receives vehicle. Mice are weighed weekly and tumor volumes determined weekly for 10 weeks. Mice of each group grow and gain weight. Significant differences in average mouse body weight are not observed between cohorts at any interval. The tumors of control mice grow to a volume of approximately 1100 cubic millimeters within 10 weeks.

As shown in Table 4, significant (p<0. 1) differences in tumor volume are observed between tumors of mice administered vehicle and mice receiving 1000mg/kg/day by week seven and continuing through week 10. Treatment with the extract at this concentration results in a 68% inhibition in A549 tumor development during the 10 weeks of assessment. Significant differences are not observed between tumors of control mice and mice of the 1000 mg/kg/day group at any weekly interval from week 1 through week 6. Similarly, no significant differences in tumor volume are noted between those of control mice and mice of the 200mg/kg/day group at any interval during the 10 weeks of assessment.
