Abstract:
Disclosed is a method of enhancing the response of cancer cells in a mammal to treatment with a death receptor ligand, which method comprises contacting the cancer cells with a death receptor ligand in conjunction with an effective amount of a compound described herein, for example, a cucurbitacin (I) or a withanolide (II). Also disclosed is a method of inducing apoptosis in cancer cells in a mammal, comprising contacting the cancer cells with a compound described herein, for example, a cucurbitacin (I) or a withanolide (II) and also contacting the cancer cells with a death receptor ligand, whereby apoptosis is induced in the cancer cells.
Abstract:
A composition comprising a substantially purified compound of the formula: in combination with at least one additional therapeutic agent, and methods of preventing or treating cancer and a condition treatable by the inhibition of vacuolar-type (H+)-ATPase.

Abstract:
The present invention provides novel antiviral compounds, refered to as calanolides, related compounds, and their derivatives, which may be isolated from plants, or derived from compounds from plants, of the genus Calophyllum in accordance with the present inventive method. The compounds and their derivatives may be used alone or in combination with other antiviral agents in compositions, such as pharmaceutical compositions, to inhibit the growth or replication of a virus, such as a retrovirus, in particular a human immunodeficiency virus, specifically HIV-1 or HIV-2.
Abstract:
The present invention provides a compound of the formula (I) or (II, wherein R1 is H, alkyl, alkenyl or aryl, R2 is H, alkyl or aryl, R3 is H, a alkyl, alkenyl or aryl, R4 and R4-R8 are independently R10, C(O)R10 or SO2R10, wherein R10 is H, alkyl, alkenyl or aryl, and R9 is R9a, C(O)R9a or SO2R9a, wherein R9a is H, alkyl, alkenyl or aryl. R9a can be unsubstituted or substituted with one or more oxo(═O), OR9b, OC(O)R9b, OSO2R9b, NHR9b, NHC(O)R9b and NHSO2R9b groups. R9b is H, alkyl, alkenyl, or aryl. R9b can be unsubstituted or substituted with one or more groups such as oxo(═O), OR9c, CO2R9c, CO2R9c and OC(O)R9c. R9c is H, or a unsubstituted or substituted alkyl, alkenyl or aryl. The present invention further provides a composition comprising at least one compound of the present invention and a pharmaceutically acceptable carrier, alone or in combination with at least one additional active agent. The present invention further provides a method of treating a condition treatable by the inhibition of vacuolar-type (H+)-ATPase and a method of treating cancer.
