The rational design, synthesis, and biological activity of phosphonyl- and phosphinyl-linked bisubstrate analog inhibitors of the enzyme Ras farnesyl protein transferase (FPT) are described. The design strategy for these bisubstrate inhibitors involved connection of the critical binding components of the two substrates of FPT (ras protein and farnesyl pyrophosphate, FPP) through a phosphonyl- or phosphinyl-bearing
描述了Ras farnesyl蛋白转移酶(FPT)的膦酰基和次膦酰基连接的双底物类似物抑制剂的合理设计,合成和生物学活性。这些双底物抑制剂的设计策略涉及通过带有膦酰基或次膦酰基的接头连接FPT的两种底物的关键结合成分(ras蛋白和法呢基焦磷酸酯,FPP)。发现该系列的第一个实例化合物14是有效的FPT抑制剂(I50 = 60 nM)。用VVM替换14中的VLS三肽序列后,观察到活性进一步提高15倍(15,I50 = 6 nM)。次膦酸类似物16(I50 = 6 nM)与膦酸15等价。化合物14-16对紧密相关的I型香叶基香叶基蛋白质转移酶GGT-1提供了FPT的1000倍选择性[14,I50(GGT-I)= 59 microM; 15 I50(GGT-1)= 10 microM; 16 I50(GGT-1)= 21 microM]。制备了甲基和POM酯前药17-19,并在全细胞分析中进行了
