Three major monodesmethyl metabolites of (+)-13a-(S)-deoxytylophorinine were synthesized stereospecifically and their configurations at C-13a were determined. Biological assays revealed that one of the metabolites, 3-O-desmethyl-13a-(S)-deoxytylophorinine, had a higher cytotoxic potency than the parent compound or the positive controls doxorubicin (Adriamycin) and paclitaxel (Taxol).
