The rational design, synthesis, and biological activity of farnesyl diphosphate (FPP)-based inhibitors of the enzyme Ras farnesyl protein transferase (FPT) is described. Compound 3, wherein a beta-carboxylic phosphonic acid type pyrophosphate (PP) surrogate is connected to the hydrophobic farnesyl group by an amide linker, was found to be a potent (I50(FPT) = 75 nM) and selective inhibitor of FPT,
描述了基于法呢基二磷酸(FPP)的Ras法呢基蛋白转移酶(FPT)酶的抑制剂的合理设计,合成和生物学活性。发现化合物3(其中β-羧酸膦酸型焦磷酸酯(PP)替代物通过酰胺连接基与疏水性法呢基连接)是有效的(I50(FPT)= 75 nM)和选择性的FPT抑制剂,如其抗角鲨烯合成酶(I50(SS)= 516 microM)和甲羟戊酸激酶(I50(MK)=> 200 microM)的活性较弱而得到证明。进行了系统结构-活性关系研究,涉及法呢基,酰胺连接基和3的PP替代基的修饰。β-羧酸膦酸PP替代物的羧基和膦酸基团对于活性都是必不可少的,因为任一组的缺失都会导致活性降低50-2600倍(6-9,I50 = 4.6-220 microM)。法呢基也显示出非常严格的要求,并且不耐受一个碳的同源性(12,I50 = 17.7 microM),被十二烷基片段取代(14,I50 = 9 microM)或在烯丙基位置引入额外的甲基(
