Microsomal prostaglandin E-2 synthase (mPGES)-1 and 5-lipoxygenase (5-LO) are pivotal enzymes in the biosynthesis of the pro-inflammatory PGE(2) and leukotrienes, respectively. The design and synthesis of a second series of mPGES-1 inhibitors based on a triazole scaffold are described. Our studies allowed us to draw a tentative SAR profile and to optimize this series with the identification of compounds 10, 11 and 14-15 which displayed potent mPGES-1 inhibition in a cell-free assay. In addition, compounds 5, 10, 12 and 14-16 also blocked 5-LO activity in cell-free and cell-based test systems, emerging as very promising candidates for the development of safer and more effective anti-inflammatory drugs.

used in silico screening to rapidly direct the synthesis, based on the copper-catalyzed 3 + 2 Huisgen's reaction (clickchemistry), of potential inhibitors. We designed 26 new triazole-based compounds in accordance with the pocket binding requirements of human mPGES-1. Docking results, in agreement with ligand efficiency values, suggested the synthesis of 15 compounds that at least in theory were shown
