Synthesis and Cytotoxicity of Two Active Metabolites of Larotaxel.

ABSTRACT

Two epimeric metabolites of Larotaxel were synthesized in eight steps from 10-DAB III as a commercial material and their structures were characterized using NMR and MS spectral data. The cytotoxicity of two metabolites was performed on breast cancer cell lines MCF-7, MX-1 and MDA-MB-231. It is remarkable that both of these two desired taxanes showed great potent cytotoxic effect.
