The present invention comprises peptidomimetic compounds which comprise a suitably substituted aminoalkylbenzene and analine analogs, further substituted with a second phenyl ring attached via a bond, a heteroatom linker or an aliphatic linker. 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.
本发明涵盖了包含适当取代的氨基烷基苯和苯胺类似物的肽类似物化合物,进一步取代了通过键连接的第二苯环、杂原子连接物或脂肪连接物。这些化合物抑制了法尼基蛋白转移酶酶和某些蛋白的法尼酰化。此外,这些法尼基蛋白转移酶抑制剂与先前描述的抑制法尼基蛋白转移酶的抑制剂不同,因为它们不具有硫醇基团。缺乏硫醇基团在改善动物体内药代动力学行为、预防硫醇依赖性化学反应(如快速自氧化和与内源硫醇形成二硫键)以及减少全身毒性方面提供了独特的优势。本发明还包括含有这些法尼基转移酶抑制剂的化疗组合物和其生产方法。
