The present invention comprises peptidomimetic compounds which comprise a suitably substituted aminoalkylbenzamide moiety. The instant compounds inhibit the farnesyl protein transferase enzyme and the farnesylation of certain proteins. Furthermore, the instant farnesyl protein transferase inhibitors 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. Further contained in this invention are chemotherapeutic compositions containing these farnesyl transferase inhibitors and methods for their production.
本发明涉及一种包含适当取代的
氨基烷基苯甲酰胺基团的肽类似物化合物。这些化合物能够抑制法尼酰基蛋白转移酶和某些蛋白质的法尼酰化。此外,这些法尼酰基蛋白转移酶
抑制剂与以前描述的法尼酰基蛋白转移酶
抑制剂不同,因为它们不具有巯基。缺乏巯基提供了独特的优势,可以改善动物的药代动力学行为,防止巯基依赖性
化学反应,如快速自氧化和与内源性巯基形成二
硫键,以及减少系统毒性。此外,本发明还包括含有这些法尼酰转移酶
抑制剂的化疗组合物和其生产方法。
