Abstract

A novel series of compounds, derived from 2,5-functionalized imidazoles, have been synthesized as potential bisubstrate inhibitors of protein farnesyltransferase (FTase) using structure-based design. These compounds have a 1,4-diacid chain and a tripeptide connected by an imidazole ring. The synthetic strategy relies on the functionalization at the C-2 position of the heterocycle with the diacid side chain and peptide coupling at the C-5 position. Several new compounds were synthesized in good yields. Kinetic experiments on the most active compounds revealed different binding modes depending on the diacid chain length.
