Potent and selective non-cysteine-containing inhibitors of protein farnesyltransferase.
Potent and selective non-thiol-containing inhibitors of protein farnesyltransferase are described. FTI-276 (1) was transformed into pyridyl ether analogue 19. The potency of pyridyl ether 19 was improved by modification of the biphenyl core to that of an o-tolyl substituted biphenyl core to give 29. In addition to 0.4 nM in vitro potency, 29 displayed 350 nM potency in whole cells as the parent carboxylic acid. The o-tolyl biphenyl core dramatically and unexpectedly enhanced the potency of other compounds as exemplified by 46, 47, 48, and 49.
