Selective inducible microsomal prostaglandin E(2) synthase-1 (mPGES-1) inhibitors derived from an oxicam template.
Here we describe the SAR of a series of potent and selective mPGES-1 inhibitors based on an oxicam template. Compound 13j demonstrated low nanomolar mPGES-1 inhibition in an enzyme assay. In addition, it displayed PGE(2) inhibition in a cell-based assay (0.42microM) and had over 238-fold selectivity for mPGES-1 over COX-2 and over 200-fold selectivity for mPGES-1 over 6-keto PGF(1alpha).
