bioactive tubulin-binding conformation of paclitaxel (Taxol™) is crucial to a full understanding of the bioactivity of this important anticancer drug, and potentially also to the design of simplified analogs. The bioactive conformation has been shown to be best approximated by the T-Taxol conformation. As a further test of this conclusion, the paclitaxel analog 4 was designed as a compound which has all the
了解紫杉醇 (Taxol ™ )的生物活性微管蛋白结合构象对于全面了解这种重要抗癌药物的生物活性至关重要,并且可能对简化类似物的设计也很重要。生物活性构象已被证明最接近于 T-紫杉醇构象。作为对这一结论的进一步检验,紫杉醇类似物4被设计为具有活性所需的所有化学功能但不能采用 T-紫杉醇构象的化合物。的合成和生物测定4证实了它的缺乏活动,并因此提供了用于在T-紫杉醇构象生物活性微管蛋白结合的构象的进一步支持。
