Benefits of technology

The patent text describes the use of extracts of black cohosh to treat or prevent neoplasia (tumors). The extracts contain actein and triterpene-glycoside, which have been found to have anti-neoplastic effects when used alone or in combination with other chemopreventive or chemotherapeutic agents. The invention provides a composition for this purpose and a method for treating or preventing neoplasia by administering the extracts to a subject. The technical effect is a synergistic anti-neoplastic effect that can be achieved by combining the extracts with other chemopreventive or chemotherapeutic agents.

Problems solved by technology

Although most studies report that black cohosh is free of significant side-effects, these studies have not been carried out for a length of time sufficient to ensure the safety of black cohosh with respect to uterine function and / or the induction or stimulation of breast cancer growth.
However, little is known about the mechanisms by which these compounds are metabolized in vivo.
All of the foregoing studies, however, have been limited in scope, and have not addressed issues of specificity and mechanism of action.

Chemicals and Reagents

[0097]Polyamide resin SC618CC silica gel (40 μM) was obtained from J. T. Baker (Phillipsburg, N.J.), and the RP18F254 plate (1-mm layer thickness) was obtained from EM Science (Darmstadt, Germany). Actein, 27-deoxyactein (23-epi-26-deoxyactein) (Zheng et al., CimiPure (Cimicifuga racemosa): a standardized black cohosh extract with novel triterpene glycoside for menopausal women. In Phytochem. Phytopharm., Shahidi and Ho, eds. (Champaign, Ill.: AOCS Press, 2000) pp. 360-70), cimifugoside, and cimiracemoside A were obtained from ChromaDex (Laguna Hills, Calif.), and 27-deoxyactein was also obtained from Herbstandard (Chesterfield, Mo.). Tamoxifen, 5-fluorouracil (5-FU), doxorubicin, cisplatin, and paclitaxel were purchased from Sigma (St. Louis, Mo.). Herceptin was obtained from Genentech (CA). Cimigenol and cimigenol glycoside were obtained from Dr. WC Ye (Department of Phytochemistry, China Pharmaceutical University, Nanjing 210009, China).

Separation of the Ethyl Acetate Extract

[0100]As shown in FIG. 1, black cohosh roots and rhizomes were extracted with 80% methanol (MeOH) / H2O, and partitioned with n-hexane. Two layers were obtained: a water layer and an n-hexane layer. N-hexane was used to extract the non-polar phytochemicals, respectively, with yields of 0.05% hexane, 0.73% ethyl acetate, and 1.69% water. The water layer was partitioned with ethyl acetate, and two fractions were obtained: a water layer and an ethyl acetate layer. Ethyl acetate was used to extract the mid-polar and polar phytochemicals. The ethyl acetate layer was dried and evaporated to yield an ethyl acetate extract. The triterpene glycosides and cinnamic acid esters were separated from the ethyl acetate extract by polyamide chromatography (Kruse et al., Fukic and piscidic acid esters from the rhizome of Cimicifuga racemosa and the in vitro estrogenic activity of fukinolic acid. Planta. Med., 65:763-64, 1999).

Abstract

A method for treating, preventing or ameliorating breast cancer is provided by administering a synergistic amount of digitoxin and either actein or an extract of black cohosh comprising triterpene glycosides, and optionally another chemopreventive agent which may be paclitaxel. Methods for treating or preventing a neoplasia using a synergistic combination, and compositions of a synergistic combination of a cardiac glycoside and either actein or an extract of black cohosh comprising triterpene glycosides, and optionally another chemopreventive agent which may be a taxane are also provided. The compositions may also be used in a method for modulating Na+K+ATPase activity. In addition, a method for inhibiting the progression or development of breast cancer in vivo by administering either actein or an extract of black cohosh comprising triterpene glycosides and optionally at least one other chemoprotective agent is provided.
