The enzyme isoprenylcysteine carboxyl methyltransferase (Icmt) plays an important role in the post-translational modification of proteins that are involved in the regulation of cell growth. The indole acetamide cysmethynil is by far the most potent and widely investigated Icmt inhibitor, but it has modest antiproliferative activity and may have pharmacokinetic limitations due to its lipophilic character
异戊烯基半胱氨酸羧基甲基转移酶(Icmt)在参与细胞生长调节的蛋白质的翻译后修饰中起着重要作用。吲哚乙酰胺氰菊酯是迄今为止最有效和研究最广泛的Icmt抑制剂,但它具有适度的抗增殖活性,并且由于其亲脂性而可能具有药代动力学限制。我们在这里报告说,可以将cysmethynil进行结构修饰,以产生与抑制Icmt一样有效但具有显着更大的抗增殖活性的类似物。关键的修饰是用叔氨基取代乙酰胺侧链,用异戊二烯基取代正辛基侧链,然后用5- m-甲苯基环被氟取代。而且,这些类似物具有较低的亲脂性,这可以导致改善的药代动力学特征。
