A series of 94 taxol analogues exhibiting antitumor activity were investigated using comparative molecular ficld analsis (CoMFA) method. The most optimal CoMFA from 80 compounds selected randomly . yielded a two-components model, with siginficant cross-validation r cv of 0.640 and conventional r of 0.868. The robustness of the CoMFA model was further validatal by prediedon Of 14 test set componds. The CoMFA model explained present SAR and prtcularly the importance of the hydroxyl group at C-2’ position and the stereochemistry at C-2’ and C-3’
