An efficient synthesis of a C16 side chain benzophenone analogue of cryptophycin-24 using a crotylboration reaction and Heck coupling as key steps is described. In an in vitro tubulin assembly assay, the benzophenone analogue of the beta isomer (IC(50)=7.4 microM) is twice as active as cryptophycin-24 (IC(50)=15 microM).
描述了使用巴豆基硼化反应和Heck偶联作为关键步骤,高效合成隐藻霉素24的C16侧链二苯甲酮类似物。在体外微管蛋白组装测定中,β异构体的二苯甲酮类似物(IC(50)= 7.4 microM)的活性是隐藻素-24(IC(50)= 15 microM)的两倍。
