Patent number: 6586461Abstract: Farnesyl diphosphate analogs, specifically the 3-substituted alcohol precursors of the diphosphate analogs, 3-allylfarnesol and 3-vinylfarnesol, are potent inhibitors of mammalian protein fanesyltransferase (FTase). 3-allylgeranylgeraniol is a highly specific cellular inhibitor of protein geranylgeranylation (GGTase I). Furthermore, these compounds are able to efficiently block the anchorage-dependent growth of ras transformed cells. While 3-allylfarnesol inhibits protein farnesylation in situ, 3-vinylfarnesol instead leads to the abnormal prenylation of proteins with the 3-vinylfarnesyl group. In a similar manner, treatment with 3-allylgeranylgeraniol inhibits protein geranylgeranylation while 3-vinylgeranylgeraniol restores protein geranylgeranylation in cells.Type: GrantFiled: June 16, 1999Date of Patent: July 1, 2003Assignee: Wayne State UniversityInventor: Richard A.
