Abstract

SAR studies of the substitution effect on the central phenyl ring of the biphenyl scaffold were carried out using anacetrapib (9a) as the benchmark. The results revealed that the new analogs with substitutions to replace trifluoromethyl (9a) had a significant impact on CETP inhibition in vitro. In fact, analogs with some small groups were as potent or more potent than the CF(3) derivative for CETP inhibition. Five of these new analogs raised HDL-C significantly (>20mg/dL). None of them however was better than anacetrapib in vivo. The synthesis and biological evaluation of these CETP inhibitors are described.
