title: Alpha-cyanocinnamide derivatives: a new family of non-peptide, non-sulfhydryl inhibitors of Ras farnesylation.
abstract: Farnesylation of Ras and other proteins is required for their membrane attachment and normal function. Here we report on the synthesis of alpha-cyanocinnamide derivatives, a new family of farnesyltransferase inhibitors. These compounds are nonpeptidic and do not contain sulfhydryl groups. The most potent compound is a pure competitive inhibitor with respect to the Ras protein and mixed competitive with respect to farnesyl diphosphate. Selectivity studies against geranylgeranyltransferase and biological activities of selected compounds are described.
