Blocking farnesylation of oncogenic Ras proteins is a mechanism based therapeutic approach that is of current interest for the development of antitumor agents to treat ras associated tumors. As part of a SAR study on the lead farnesyl protein transferase (FPT) inhibitor I, we report here the synthesis of novel geometric isomers II and III and the FPT inhibition activity of their N-acyl and N-sulfonamido
阻断致癌性Ras蛋白的法尼基化是一种基于机制的治疗方法,目前对于开发治疗ras相关肿瘤的抗肿瘤药物具有重要意义。作为对法呢基铅蛋白转移酶(FPT)抑制剂I的SAR研究的一部分,我们在这里报告了新型几何异构体II和III的合成及其N-酰基和N-磺酰胺基衍生物15-65的FPT抑制活性。N-酰基衍生物的活性显着低于铅抑制剂I,从而表明I中N-酰基的空间位置对于化合物与FPT的结合至关重要。与I相反,N-磺酰胺基-II系列是非巯基非肽类化合物的新型先导,它们是FPT / GGPT双重抑制剂。根据最近有关N-和K-Ras异戊烯化的报道,
