Patent number: 5624936Abstract: 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.Type: GrantFiled: February 13, 1996Date of Patent: April 29, 1997Assignee: Merck & Co., Inc.Inventor: S.
