Biphenyl-substituted oxazolidinones as cholesteryl ester transfer protein inhibitors: modifications of the oxazolidinone ring leading to the discovery of anacetrapib.

The development of the structure-activity studies leading to the discovery of anacetrapib is described. These studies focused on varying the substitution of the oxazolidinone ring of the 5-aryloxazolidinone system. Specifically, it was found that substitution of the 4-position with a methyl group with the cis-stereochemistry relative to the 5-aryl group afforded compounds with increased cholesteryl ester transfer protein (CETP) inhibition potency and a robust in vivo effect on increasing HDL-C levels in transgenic mice expressing cynomolgus monkey CETP.

Novel pyrazolo[3,4-d]pyrimidine-based inhibitors of Staphlococcus aureus DNA polymerase III: design, synthesis, and biological evaluation.

6-Anilinopyrazolo[3,4-d]pyrimidin-4-ones are novel dGTP analogues that inhibit the replication-specific enzyme DNA polymerase III (DNA pol III) of Staphlococcus aureus and other Gram-positive (Gr+) bacteria. To enhance the potential of these inhibitors as antimicrobial agents, a structure-activity relationship was developed involving substitutions at the 2, 4, and pyrazolo NH positions. All of the new inhibitors were tested for their ability to inhibit S.
