Abstract
Compounds in which cysteine of the tetrapeptide CVFM has been replaced with a phenolic benzyl substituent inhibit farnesylation of H-ras pro tein by farnesyl transferase (FTase). In the most potent inhibitors (e .g,, 5-chloro-2-hydroxybenzyl-VFM, IC50 = 0.5 mu M, approx. 8 times le ss active than CVFM) the phenolic hydroxyl is ortho to the methylene l inker. Inhibitory activity is influenced by substitution on the phenol ring.
