    • The present invention comprises analogs of the CA.sup.1 A.sup.2 X motif of the protein Ras that is modified by farnesylation in vivo. These CA.sup.1 A.sup.2 X analogs inhibit the farnesyl-protein transferase and the farnesylation of certain proteins. Furthermore, these CA.sup.1 A.sup.2 X analogs differ from those previously described as inhibitors of farnesyl-protein transferase in that they do not have a thiol moiety. The lack of the thiol offers unique advantages in terms of improved pharmacokinetic behavior in animals, prevention of thiol-dependent chemical reactions, such as rapid autoxidation and disulfide formation with endogenous thiols, and reduced systemic toxicity. The compounds of the instant invention also incorporate a cyclic amine moiety in the A.sup.2 position of the motif. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.
    • 本发明包括通过体内法尼基化修饰的蛋白Ras的CA1A2X基序的类似物。 这些CA1A2X类似物抑制法呢基蛋白转移酶和某些蛋白质的法呢基化。 此外,这些CA1A2X类似物与先前描述为法呢基 - 蛋白转移酶抑制剂的不同之处在于它们不具有硫醇部分。 缺乏硫醇在改善动物药代动力学行为方面提供独特的优势,防止硫醇依赖的化学反应,如快速自身氧化和内源性硫醇形成二硫键,并减少全身毒性。 本发明的化合物还在基序的A2位置加入环胺部分。 本发明还包含含有这些法呢基转移酶抑制剂的化疗组合物及其生产方法。
