Abstract

A series of novel docetaxel analogues possessing a peptide side chain at the C3'-N position was synthesized. These compounds were designed to mimic a region of the alpha-tubulin loop that is equivalent to the paclitaxel binding pocket in beta-tubulin. Eight new peptidic taxoids were obtained and evaluated as inhibitors of microtubule disassembly, as well as for their cytotoxicity.

摘要

合成了一系列在C3'-N位置具有肽侧链的新型多西他赛类似物。设计这些化合物是为了模拟α-微管蛋白环中与β-微管蛋白中的紫杉醇结合口袋相当的区域。获得了8种新的肽类紫杉烷，并对其作为微管解聚抑制剂以及细胞毒性进行了评估。
