Reduced or demethylated variants of a C(13)-desmethylene congener of the marine microtubule stabilizer (−)-zampanolide have been prepared by HWE-based macrocyclization and stereoselective construction of the hemiaminal center in the side chain. While all modifications led to reduced growth inhibitory activity, the 2,3-dihydro and the C(17)-desmethyl variants retained potent antiproliferative activity
海洋微管稳定剂 (-)-zampanolide 的 C(13)-去亚甲基同系物的还原或去甲基化变体已通过基于 HWE 的大环化和侧链半缩醛中心的立体选择性构建来制备。虽然所有修饰都会导致生长抑制活性降低,但 2,3-二氢和 C(17)-去甲基变体保留了有效的抗增殖活性,对多种癌细胞系具有个位数至低两位数的纳摩尔 IC 50 值。
