00 0 0 FIELD OF THE INVENTION S The compounds and compositions in this invention inhibit tumor or cancer growth.

N BACKGROUND OF THE INVENTION We have identified an herbal extract from Xanthoceras sorbifolia that inhibits cancer cell's growth. The active compounds were purified and their structures identified to be novel triterpenoid saponins. We named them as Xanifolia-Y and family.

Varicose veins are swollen and knotted veins that can occur in any part of the body, especially in the calf, inside leg or around the anus. Escin has been satisfactorily used for 0 treating Varicose veins and chronic venous insufficiency for many years. Escin is a mixture of saponins found in the seed of the horse chestnut tree, Aesculus hippocastanum L., Hippocastanaceae. Escin is the major active ingredient prepared from Aesculus hippocastanum (Hippocastanaceae), the horse chestnut tree. In one controlled trial study, aescin was shown to be as effective as compression therapy as an alternative to medical treatment for CVI. The therapeutic benefit is well supported by a number of experimental investigations in different animal models. See Department of Pharmacological Sciences, University of Milano, Via Balzaretti 9, 20133 Milano, Italy. New saponin compounds with two angeloyls have been provided in International PCT Application No. PCT/US04/33359, filed October 8, 2004, and U.S. Serial No. 10/906,303.

0 The aquaporins (AQPs) are a family of homologous water channels expressed in many epithelial and endothelial cell types involved in fluid transport. The family of mammalian AQPs consists of 11 members, AQPO-10, each with a distinct tissue. Functional measurements indicate that mammalian AQPs 1, 2, 4, 5, and 8 are probably water selective, whereas AQPs 3, 7, 9, and 10 also transport glycerol and other small solutes. They are expressed at part of membrane of cell. AQP1 protein is strongly expressed in most microvessel endothelia outside of the brain, as well as in endothelial cells in cornea, intestinal lacteals, and in other tissues AQP1 protein was strongly expressed in the membrane of microvessels and small vessels in all ovarian epithelial tumors, but less at the cytoplasm of tumor cells. In addition, AQP1 protein was also observed in the membrane of interstitial cells of ovarian carcinoma.

Incorporated by reference of: The influence of aquaporin-1 and microvessel density on ovarian carcinogenesis and ascites formation, J.H. Yang et al., 2006 IGCS, International Journal of Gynecological Cancer 16 (suppl. 1) Structural determinants of water permeation through aquaporin-1, by Kazuyoshi Murata, et al., Nature, Vol. 407, October 5, 2000 The distribution amount of AQPs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 are varied at membrane of different cells. In different tumor cell, certain type of Aquaporin proteins is over-expressed.

10 An increasing number of disturbances have been found associated to abnormal function of S these proteins. The compounds Xanifolia can interact with the aquaporin and inhibit the C tumor cell growth. We used Western blot analysis and identified expression of aquaporin in cell lines. Detail of Xanifolia in PCT/US2005/031900, filed September 7, 2005, and U.S.

Serial 11/131551, filed May 17, 2005.

A Western blot is a common method in molecular biology/biochemistry/immunogenetics to detect protein in a given sample of tissue homogenate or extract. It uses gel electrophoresis 00 00 to separate proteins by mass. The proteins are then transferred out of the gel and onto a 0 0 membrane, where they are "probed" using antibodies specific to the aquaporin protein. As a C result, we can examine the amount of aquaporin protein in a given sample and compare levels between several groups. Other techniques which allow detection of proteins in C1 tissues (immunohistochemistry) and cells (immunoctochemistry) are used. Other methods such as Bradford protien assay, UV spectroscopy, Biuret protein assay, Lowry protien assay, Bicinchonic acid protein assay may also be used.

There are many publications about the studies of the aquaporin as a maker for cancer cells but none of them mention the regulating or affecting the aquaporin as method to facilitate the blockage, inhibition or destroying the cancer cells.

0 This invention describes a method of destroying cancer cell or inhibiting the cancer cell proliferates by regulating or affecting the aquaporin. In an embodiment, the saponin with two angeloyl groups can interacts with the aquaporin in order inhibiting the cancer cell growth. In an embodiment the compound may be selected from formula (1B) (1C) and In an embodiment, the compound comprises a triterpene backbone, two angeloyl groups and sugar moiety. In an embodiment, the compound comprises a triterpene backbone, two acetyl groups with 2 or more carbon and sugar moiety. In an embodiment the compound(s) are selected from Xanifolia (YO, Y1, Y2, Y, Y7, Y8, Y9, and Y10). In an embodiment the compound(s) are selected from Xanifolia Escin or Aescin. In an embodiment the compound(s) are selected from Compound A to X and Al to X1 in the application.

In embodiment the method is blocking the cancer cell proliferates by regulating, interacting or affecting the aquaporin. In embodiment, the method is increase the water permeability of the cell membrane by regulating or affecting the aquaporin in order to kill the cell. In an embodiment, the method is affecting the aquaporin permitting extra water into the cell to damage the cancer cell. In an embodiment, the method is affecting the aquaporin permitting Glycerol related solute into the cell to damage the cancer cell. In an embodiment, the method is affecting the aquaporin regulating water into the cell to damage the cancer cell, S wherein the method comprise compound selecting from Xanifolia (YO, Y1, Y2, Y, Y7, Y8, Y9, and In embodiment, the method is adjusting the fluid density outside the cell in order to damage the cancer cell by regulating the fluid pass in the cell wherein the aquaporin is overexpressed. In an embodiment this invention makes use of the change of cell membrane permeability to damage the cancer cells. The cell membrane permeability can be changed 00 by the overexpression of some aquaporins.

0 The potency of Xanifolia(Y) is difference in different cancer cells of ovary, cervix, lung, skin and breast because they have variation of Aquaporin (AQPs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) at the membrane.

Amount of Aquarpoin (AQP 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) at the membrane in various types of ovarian cancer cells such as OVCAR3, SKOV3, TOV21G and ES2 is different therefore they show different inhibition activity when treated with Xanifolia Xanifolia is a saponin comprises a triterpene, two angeloyl groups and sugar moiety. Xanifolia inhibits tumor growth IC50= 1.5-4.5 ug/ml). Xanifolia which has a similar structure to Y but 0 with only one angeloyl group at C22, has less anticancer activity (IC50=6 ug/ml). Removal of sugars from Y (ACH-Y) but retaining the diangeloyl group retains 40% of the anticancer activity (IC50=9.5 ug/ml).

However, removal of both angeloyl groups from Y (AKOH-Y) completely abolishes its anticancer activity (even at 120 ug/ml). The results indicate that diangeloyl groups in compound Ys are important for anti-tumor activity. The diangeloyl groups pay an important role in interacting with the aquaporin for inhibiting cancer growth.

The hemolytic activities of human red blood cells by Xanifolia-Y Escin and SIGMA saponin standard were compared. Y contains two angeloyl groups, Escin has one angeloyl group and SIGMA saponin standard is a mixture of saponins from Quillaia bark. The results show that #63Y (compound Y) has higher hemolytic activity (IC50=1 ug/ml) than Escin or SIGMA saponin standard (IC50=5 ug/ml). See application PCT/US2006/016158, filed April 27, 2006, Dkt# 804-K-PCT, Figure 6 A In embodiment, the compounds of this invention interact with cancer cells and increase the static charge of the cells.

S0 To investigate the anti-tumor activity of compounds in this application, we employed cancer cell lines derived from different human organs and tested the effect on growth activity. In these preliminary studies, we found that the plant extract inhibits the growth of certain cell lines. We studied 10-15 cell-lines (derived from different human organs) with a MTT cellgrowth assay, and found that OVCAR3 cells (from ovary) to be the most sensitive (with 14.5 ug/ml). Int'l App'l No. PCT/US2004/033359 and U.S. Serial No. 10/906,303.

The active compound was then purified and named Xanifolia-Y. Its chemical structure was determined by 2D NMR and MS analysis. Xanifolia-Y is a novel triterpenoid saponin with a 0 diangeloyl group attached at one end and carbohydrates or sugar moieties at another end of the triterpene structure. In an embodiment, the diangeloyl attached at C21, C22 positions and carbohydrates or sugar moieties at C3 position of a triterpene structure. The diangeloyl group is important for its activity. The purified compound has been tested with 60 cancer cell lines. Test results show inhibition towards most cell lines tested with GI50 values ranging from 0.1 1 uM.

OVCAR3 cells, cancer cells derived from ovary, are the most sensitive to Xanifolia-Y among cell lines tested in our early studies. We subsequently tested 10 additional human ovarian cancer cell lines and found all of them to be susceptible to inhibition by Xanifolia-Y with IC50 values ranging from 2-12 uM. See experiment 11.

In vivo studies employing human ovarian carcinoma xenografts in nude mice were performed. The human ovarian cancer cells (ES2) were inoculated into the peritoneal cavity of nude mice and subsequently received Xanifolia-Y. (Experiment 7, 8, The tumor bearing mice received the drug (by i.p. route) for 10 days starting from either day 1, day 4, or day 10 after inoculations. The results show that the median survival time for tumor bearing mice without drug-treatment is approximately 20-24 days. However, there was no death for tumor bearing mice with drug-treatment starting on day 1 after tumor inoculation.

The median survival time for tumor bearing mice with drug-treatment starting on day 4 after 45 tumor inoculation is no death in 50 days; and tumor bearing mice with drug-treatment S started on day 10 after tumor inoculation is half of the mice survive in 50 days. These results indicate that the compounds of this invention are capable of increasing the survival rate of mammal.

The median survival time for tumor bearing mice with drug-treatment starting on day 4 after tumor inoculation is 58 days (extension of life span of 141%); and tumor bearing mice with 00 drug-treatment started on day 10 after tumor inoculation is 31 days (extension of life span of oO 00 These results indicate that Xanifolia-Y is capable of extending the life span of 0 mammal bearing tumors. It is useful in treating ovarian cancer in humans.

These results indicate that Xanifolia-Y is capable of extending the life span of mammal bearing tumors. It is useful in treating ovarian cancer in humans.

Among gynecological malignancies, ovarian cancer has the highest rate of mortality in women in the United States with an estimated 22,220 new cases in 2005 and over 16,000 deaths (NIH web info). The disease is often missed in diagnosis in the early stage due to asymptomatic and the lack of reliable diagnostic marker. As a result, most of the ovarian cancer patients being diagnosed are already at advanced stages. The standard treatment 0 of ovarian cancer is a combination of a platinum analogue with paclitaxel (McGuire et al., 1996; Ozols et al., 2003). Improved patients survival time was observed in patients with intraperitoneal administration of these agents (Armstrong et al., 2006). The peritoneal cavity is the principal site of disease in ovarian cancer. The improved efficacy of these agents could be due to a more direct interaction with cancer cells. However, the increase of median survival from 49.7 to 65.6 months is still far from satisfactory.

As mentioned above, our in vivo animal experiments mimicking the human situation showed that Xanifolia-Y is effective in prolonging mammal life span. Mice were inoculated with human ovarian carcinoma (ES2) in the peritoneal cavity. Starting from the mid-way (time to mortality) point of tumor progression (considered as a late stage of disease in human), drug was then administered into the peritoneal cavity. It was found that Xanifolia-Y treatment is beneficial to tumor bearing mice by prolonging their life span. Depending on the stage of the disease progression, the sooner the start of the drug-treatment, the better the results are.

Based on our results, it can prolonged the life-span of tumor bearing mice after Xanifolia-Ytreatment is due to blockage of the migration or metastasis of inoculated cancer cells into the mesothelium lining in the peritoneal cavity. In vitro studies show that Xanifolia-Y inhibits cell adhesion to culture flasks (See Experiment 13). It is known that adhesive molecules 46 play an important role in the migration and metastasis of ovarian cancer (Skubitz, 2002, S Schaller, 1996; Zetter, 1993). A major route for the spread of ovarian cancer is by the attachment of tumor cells to the mesothelium lining in the peritoneal cavity (Gardner et al., t 1995). Xanifolia-Y blocks the function of these adhesive molecules on cells. In an embodiment, Xanifolia-Y blocks the function of these adhesive molecules on carcinoma cells. In an embodiment, Xanifolia-Y blocks the function of these adhesive molecules on ovarian carcinoma cells. In an embodiment, Xanifolia-Y blocks the function of these OO adhesive molecules on the mesothelial cells. In an embodiment, Xanifolia-Y binds to the 00 adhesive proteins (by masking) on the membrane and inhibits the interaction of adhesion C 0 proteins with their receptors. In an embodiment, Xanifolia-Y action on membrane affects

(N

adhesion proteins' function in membrane. The lost of adhesion activity of cancer cells is result from direct or indirect action of Xanifolia-Y on membrane proteins.

Most of the adhesion proteins are glycoproteins. The carbohydrate moiety in adhesion proteins interact with carbohydrates from other molecules, such as saponin or Xanifolia-Y.

Xanifolia-Y has a trisaccharide at the C3 position and it was found that a loss of carbohydrates reduces its activity (Fig. 4D and 5C). Our EM studies show that Xanifolia-Y affects membrane structure and makes holes. Damage to the membrane structure could alter adhesion protein's conformation and interfere with their binding with other molecules or 0 even cause them to lose their anchorage on membrane.

Our studies of Xanifolia-Y indicate it can be used in cancer therapy, especially as a benefit to patients with late stage ovarian cancer. They indicate that our determined saponins and formulas are useful in cancer therapy by demonstrating its inhibition of tumor growth in mammal systems.

To study the effect of Xanifolia-Y on membrane structure, the morphology of cell membrane treated with Xanifolia-Y was examined with EM. In this experiment, K562 cells were treated with 5 uM of Xanifolia-Y for 60 min. Solvent DMSO and AKOH-Y (a derivative of Xanifolia-Y without the angeloyl group and it has no activity) served as controls. Cells were negative stained with 1% UAc and subsequently examined with EM. Figure 25 show that patches of pits were found in the membrane of Xanifolia-Y treated cells (Fig. 25B) but not in cells treated with the DMSO (Fig. 25A) or AKOH-Y (Fig. 25C) controls. These pits have the size from 80A to 500A (in diameter). The pits represent holes formed in the membrane. The pits are arranged in a characteristic pattern with smaller pits (80A in diameter) located in the periphery and the bigger ones (500A in diameter) in the center. The bigger holes are resulted from fusing of the smaller holes (Fig. 25D). Membrane image of cells treated with A: DMSO solvent control, 60 min (magnification: X60,000); B: Xanifolia-Y 5 uM, 60 min.

S This experiments results show that the Xanifolia-Y alters the membrane of cell. In an embodiment, it damages the membrane of cancer cell.

Xanifolia-Y can be used for inhibiting cancers cell growth or treating cancers wherein the cancers comprise breast cancer, leukocyte cancer, liver cancer, ovarian cancer, bladder cancer, prostate cancer, skin cancer, bone cancer, brain cancer, leukemia cancer, lung cancer, colon cancer, CNS cancer, melanoma cancer, renal cancer or cervix cancer,

00 wherein the cancer is preferably ovarian cancer. Among the different cell lines tested in our 0 studies, carcinoma cells derived from ovary proved to be the most sensitive, a finding which is substantiated with more human ovarian cancer cell lines. The results of animal studies with human tumor xenograft in mice show that it can extend the life span of mice bearing C tumors. The compounds of this application can extend the life span of a subject or mammal that bearing human cancer.

This application shows Xanifolia-Y is an alternate or supplemental agent to DNA-inhibition S or microtubule-targeting drugs. It could be beneficial if it is used singly or in combination C with other drugs of different mechanisms (block M-phase progression or DNA synthesis).

Our inventions show combined effect of Xanifolia-Y and paclitaxel on inhibition of ES2 cells' growth (Detail in Experiment In our animal studies, it was shown that Xanifolia-Y extended the life span of tumor bearing mice. (See Experiments 7, 8, 9, and 10). The animals died sooner if the treatment of

O

OO Xanifolia-Y was delayed (comparing results of treatments started from 1, 4 or 10 days after 0 0 tumor inoculation). The results show that Xanifolia-Y inhibits migration or metastasis of the C inoculated cancer cells. Ovarian carcinoma cells express high levels of adhesion molecules.

Adhesion proteins are present in both cancer cells and mesothelial cells. While the lost of C adhesion is blocking of the protein accessibility due to direct binding to Xanifolia-Y, In an embodiment, the interaction of Xanifolia-Y with membrane alter indirectly the adhesion protein's binding site(s).

We have shown that Xanifolia-Y are cytotoxic to tumor cells, in an embodiment it kills ovarian cancer cells. Our inventions show that Xanifolia-Y inhibits cancer cell growth and prolongs life-span of tumor bearing mice. Our studies also indicate that the sooner the drug- 0 treatment, the longer the life-span of the tumor bearing animals is extended. Xanifolia-Y also has an effect in blocking or inhibiting migration or metastasis. The delay of Xanifolia-Ytreatment allows more chances for cancer cells to metastasize to the mesothelium lining in the peritoneal cavity which resulted in more tumor growth and shorter life span. Adhesive molecules play an important role in cell migration and metastasis. It was shown in our studies that Xanifolia-Y inhibits cell attachment to culture flasks. Xanifolia-Y interferes with the function of the adhesive molecules. In embodiment Xanifolia-Y blocks the function of the adhesive molecules. In an embodiment, Xanifolia-Y binds directly to adhesive proteins. It is masking the adhesive proteins. In an embodiment, Xanifolia-Y indirectly alters membrane structure that cause changes in protein conformation, or locations and result in loss of adhesion process.

We obtained 10 more human ovarian carcinoma cell-lines of these histological subtypes for these studies. The inhibition activity exerted by Xanifolia-Y was determined with MTT assay. The following table shows the IC50 values of Xanifolia-Y on these cell lines.

Results: 0 Table 2. IC50 values of human ovarian carcinoma determined by MTT assay.

Cell lines Tpes IC50 (uM) OVCAR3 Serous 2.2 TOV-21G Clear cell 2.2 ES2 Clear cell 4.4 RMG2 Clear cell 8.8 OVCA 429 Serous 7 OVCA 432 Serous 4.4 OVCA 433 Serous 8.8 Caov 3 Serous 7 SKOV 3 Serous 10.5 Hey 8A Serous 10.5 The IC50 values of Xanifolia-Y in these cell-lines are ranging from 2 to 10 uM. These studies show that the effective concentration of Xanifolia-Y is in the micro-molar range which is comparable to those of other anti-cancer drugs.

Experiment 12: Study apoptosis induced by Xanifolia-Y.

Experiment of apoptosis of OVCAR3 cells after treatment with Xanifolia-Y was assessed with flow cytometry of GFP-Annexin-V and propidium iodide.

Results were shown in Fig. 25 which indicates that induction of the early apoptosis (the S lower right quadrant) and late a poptotic/necrosis (the upper right quadrant) were found in cells 24 h after exposure to Xanifolia-Y. By comparing the distribution of apoptotic/necrotic cells after the drug-treatment, a higher number of early apoptotic cells were observed as compare to those of the late apoptotic/necrosis cells. These results indicate that apoptosis is a major form of cell death induced by Xanifolia-Y.

See Figure 24.

00 00 Experiment 13: Effect of Xanifolia-Y on membrane structure (EM studies).

O 0 Xanifolia-Y has a potent hemolytic activity in red blood cells (Fig. 26). To study the effect of C Xanifolia-Y on membrane structure, the morphology of cell membrane treated with Xanifolia-Y was examined with EM. In this experiment, K562 cells were treated with 5 uM C of Xanifolia-Y for 60 min. Solvent DMSO and AKOH-Y (a derivative of Xanifolia-Y without the angeloyl group and it has no activity) served as controls. Cells were negative stained with 1% UAc and subsequently examined with EM.

Figure 25 show that patches of pits were found in the membrane of Xanifolia-Y treated cells (Fig. 25B) but not in cells treated with the DMSO (Fig. 25A) or AKOH-Y (Fig. 25C) controls.

These pits have the size from 80A to 500A (in diameter). The pits represent holes formed in 0 the membrane. The pits are arranged in a characteristic pattern with smaller pits (80A in diameter) located in the periphery and the bigger ones (500A in diameter) in the center.

The bigger holes are resulted from fusing of the smaller holes (Fig. Membrane image of cells treated with A: DMSO solvent control, 60 min (magnification: X60,000); B: Xanifolia-Y 5 uM, 60 min. (X60000); C: AKOH-Y, 20 uM, 60 min. (X60000); D: Xanifolia-Y 5 uM, 60 min. (X20000) This experiments results show that the Xanifolia-Y alters the membrane of cell.

Experiment 14: Inhibition of cell adhesion by Xanifolia-Y.

Methods and Results. ES2 or Hey8A cells were plated in T25 flasks with medium containing 5 ug/ml of Xanifolia-Y. Cultures were incubated for 5 hours. Attached cells were removed from flasks by trypsinization and the amounts were counted. Compare to no drug controls, 86 4 of ES2 cells and 67 8 of Hey8A cells were found attached to flasks under this condition. At 5 ug/ml Xanifolia-Y, over 90% of unattached cells are alive as determined by the trypan Blue exclusion assay and by their ability to re-attach to flasks when plating in medium without Xanifolia-Y. However, with 10 ug/ml Xanifolia-Y, less than of cells attached to flasks and many of them are dead cells. This experiment shows that Xanifolia-Y inhibits cells adhesion process.

56 Experiment 15: Combined inhibition effect of Xanifolia-Y and Paclitaxel.

Methods: ES2 cells were exposed to Xaniffolia-Y with concentrations of 40, 20, 10, 5, and 1.25 ug/ml; or (ii) Paclitaxel with concentrations of 10, 5, 2.5, 1.25, 0.62 and 0.031 ng/ml; or (iii) Combined Xanifolia-Y and Paclitaxel with concentrations of each drug in same order (for example, 40 ug/ml Y plus 10 ng/ml T; 20 ug/ml Y plus 5 ng/ml T, etc.). Cells growth under these conditions was determined by the MTT assay.

Results: The IC50 for Xanifolia-Y and Paclitaxel, is 5ug/ml and 1.25 ng/ml, respectively.

00 00 Additive effect was observed when both drugs were used, because in this case, the 0 0 value for Paclitaxel (0.625 ng/ml) and for Xanifolia-Y (2.5 ug/ml) is less than those when C they are used singly.

See Figure 26.

Experiment 18: Determination of Aquaporin in HeLa and OVCAR3 cells.

Methods: 1. Hela or OVCAR3 cells were cultured in RPMI 1640 medium at 37C in an incubator with 5% C02.

2. Cells were harvested, washed with PBS.

3. Cellular protein was dissolved in SDS sample buffer with protease inhibitors (PMSF 0 and Leupeptin) and was incubated at 70C for 20 min before use.

4. Equal amounts of protein from Hela or OVCAR3 cells were separated with 12% SDS gel and subsequently blotted on nitrocellulose paper.

Western blot was performed with anti-AQ1 antibody (Chemicon/SIGMA) and second antibody which was conjugated with Alkaline phosphatase.

Results: The following figure shows the results of Western blot.

Aquaporin-1 (indicated with an arrow) was observed in OVCAR3 cells but was minimally detected in HeLa cells.

Based on same amounts of protein loading into gel, it was found that OVCAR3 cells have higher concentration of Aquaporin-1 than in Hela cells.

Since OVCAR3 cells are more sensitive to Xanifolia-Y and it has a higher concentration of Aquaporin-1, these results show Xanifolia-Y is potent to inhibit the cancer cell growth wherein the Aquaporin is overexpressed.
