A series of 2'-methyl taxoids were synthesized and essayed for growth inhibition experiments conducted in human ovarian cancer cell line A2780wt and its counterparts A2780cis, A2780tax, and A2780adr, resistant to cisplatin, paclitaxel, and doxorubicin, respectively, to test the effect of this substituent on the antitumor activity. Additional experiments were performed on MCF-7 human breast cancer cell line and MCF7-R resistant to doxorubicin. In several cases these taxoids were more active than paclitaxel showing subnanomolar IC50 values.
