Some C-7 modified analogs of 3, a taxane with high affinity for binding to microtubules, were prepared through multistep transformations. Most of the analogs, bearing less lipophilic C-7 substituents than propionyl in 3, exhibited comparable binding affinities to microtubules but less cytotoxicity against drug-sensitive as well as multidrug-resistant tumor cells overexpressing P-glycoprotein. In addition, these C7 modifications increased P-glycoprotein-mediated drug transport in both directions in a Caco-2 cell assay.
