Abstract
The invention provides novel saponin mixtures and compounds which are isolated from the species Acacia victoriae and methods for their use. These compounds may contain a triterpene moiety, such as acacic or oleanolic acid, to which oligosaccharides and monoterpenoid moieties are attached. The mixtures and compounds have properties related to the regulation of apoptosis and cytotoxicity of cells and exhibit potent anti-tumor effects against a variety of tumor cells.
Claims18
A composition comprising a triterpene moiety attached to a monoterpene moiety having the molecular formula:
- or a pharmaceutical formulation thereof, wherein
- a) R1 is selected from the group consisting of C1-C5 alkyl and an oligosaccharide comprising at least fucose, xylose, and N-acetyl glucosamine;
- b) R2 is selected from the group consisting of hydrogen, C1-C5 alkyl, and a saccharide;
- c) R3 is selected from the group consisting of hydrogen, hydroxyl, C1-C5 alkyl, C1-C5 alkylene, C1-C5 alkyl carbonyl, a sugar, and a monoterpene group;
- and
- d) the formula further comprises R4, wherein R4 is selected from the group consisting of hydrogen, hydroxyl, C1-C5 alkyl, C1-C5 alkylene, C1-C5 alkyl carbonyl, a sugar, C1-C5 alkyl ester, and a monoterpene group, and wherein R4 may be attached to the triterpene moiety or the monoterpene moiety.
