Selective inducible microsomal prostaglandin E2 synthase-1 (mPGES-1) inhibitors derived from an oxicam template
摘要:
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 (0.42 mu M) and had over 238-fold selectivity for mPGES-1 over COX-2 and over 200-fold selectivity for mPGES-1 over 6-keto PGF(1 alpha).

arylation of anilines with non-activated aryl halides has been achieved by a metalla-tautomerism approach. The reactivity of an aniline towards a palladium catalyst was relayed from the NH group into the aromatic ring. Out of four possible positions, the catalytic arylation was directed exclusively into the para-C−H position by a bulky ligand at the palladium in combination with a temporarily installed shielding
