A series of peptidomimetics based on a hydroxyproline scaffold was prepared
and evaluated for inhibition of farnesyltransferase and geranylgeranyltran
sferase I in both enzymatic and cell-based assays. A number of analogs were
potent and selective inhibitors of FTase, while one compound (22) was nons
elective in the enzymatic assays but eight-fold selective for inhibition of
GGTase in the cellular assay (IC50 = 0.39 mu M) (C) 1999 Elsevier Science
