Design, synthesis, and biological evaluation of (2R,alphaS)-3,4-dihydro-2-[3-(1,1,2,2-tetrafluoroethoxy)phenyl]-5-[3-(trifluoromethoxy)-phenyl]-alpha-(trifluoromethyl)-1(2H)-quinolineethanol as potent and orally active cholesteryl ester transfer protein inhibitor

Abstract

With the goal of identifying a CETP inhibitor with high in vitro potency and optimal in vivo efficacy, a conformationally constrained molecule was designed based on the highly potent and flexible 13. The synthetic chemistry efforts led to the discovery of the potent and selective 12. In high-fat fed hamsters, human CETP transgenic mice, and cynomolgus monkeys, the in vivo efficacy of 12 for raising HDL-C was demonstrated to be comparable to torcetrapib.
