The present invention comprises low molecular weight peptidyl compounds that inhibit the farnesyl-protein transferase. Furthermore, these compounds differ from the mono- or dipeptidyl analogs 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.
本发明包括抑制法尼基-蛋白转移酶的低分子量肽类化合物。此外,这些化合物与先前描述的作为法尼基-蛋白转移酶抑制剂的单肽或二肽类似物不同之处在于它们不含硫醇基团。缺乏硫醇基团在动物体内具有改善药代动力学行为、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以及其生产方法。
