Metabolite Identification
Common Name6a, 3'-p-Dihydroxypaclitaxel
Description6a, 3'-p-Dihydroxypaclitaxel is a metabolite of paclitaxel. Paclitaxel is a mitotic inhibitor used in cancer chemotherapy. It was discovered in a U.S. National Cancer Institute program at the Research Triangle Institute in 1967 when Monroe E. Wall and Mansukh C. Wani isolated it from the bark of the Pacific yew tree, Taxus brevifolia and named it taxol. When it was developed commercially by Bristol-Myers Squibb (BMS) the generic name was changed to paclitaxel and the BMS compound is sold under the trademark Taxol. (Wikipedia)
