Abstract:
Fatty acid derivatives of disulfide-containing compounds (for example, disulfide-containing peptides or proteins) comprising fatty acid-conjugated products with a disulfide linkage are employed for delivery of the compounds to mammalian cells. This modification markedly increases the absorption of the compounds by mammalian cells relative to the rate of absorption of the unconjugated compounds, as well as prolonging blood and tissue retention of the compounds. Moreover, the disulfide linkage in the conjugate is quite labile in vivo and thus facilitates intracellular or extracellular release of the intact compounds from the fatty acid moieties.

International Classification:
A61K 31/365 A61K 31/517 A61K 31/337 A61K 31/704
Abstract:
The invention provides compositions comprising wilforlide A for overcoming drug resistance in cancer therapy, particularly in the treatment of cancers which have exhibited resistance to treatment by chemotherapeutic drugs. Methods and compositions for treating a cancer are disclosed. The method administers to a patient in need thereof a combination of wilforlide A and a chemotherapeutic drug. Wilforlide A and chemotherapeutic drug are administered in a combined amount effective to treat the can cer. The cancer being treated is at least in part resistant to treatment by the chemotherapeutic drug alone.
Tripterygium Wilfordii Extracts To Overcome Chemotherapy Resistance
The invention provides extracts and compositions derived from for overcoming drug resist-ance in cancer therapy. This invention relates to organic solvent extracts of and their use in cancer treatment, particularly in the treatment of cancers which have exhibited resistance to treatment by chemotherapeutic drugs. Methods of treating a cancer are disclosed. The method administers to a patient in need thereof a combination of (a) an organic solvent extract of and (b) a chemotherapeutic drug. The organic solvent extract of (a) and chemotherapeutic drug (b) are administered in a com-bined amount effective to treat the cancer. The cancer being treated is at least in part resistant to treatment by the chemotherapeutic drug (b) alone. Also disclosed are chemotherapeutic compositions comprising a combination of (a) an organic solvent extract of and (b) a chemotherapeutic drug, wherein (a) and (b) are administered in a combined amount effective to treat the cancer; and a pharmaceutically acceptable carrier.
