Jj. Kowalczyk et al., PHENOLIC REPLACEMENTS FOR CYSTEINE IN FARNESYL TRANSFERASE INHIBITORSBASED ON CVFM, Bioorganic & medicinal chemistry letters, 5(24), 1995, pp. 3073-3078
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.
