Preliminary hit-to-lead optimization of a novel series of phenylsulfonyl hydrazide derivatives, which were derived from the high throughput screening hit compound 1 (IC50 = 5700 nM against PGE(2) production), for a potent suppressor of PGE(2) production is described. Subsequent optimization led to the identification of the potent lead compound 8n with IC50 values of 4.5 and 6.9 nM, respectively, against LPS-induced PGE(2) production and NO production in RAW 264.7 macrophage cells. In addition, 8n was about 30- and > 150-fold more potent against mPGES-1 enzyme in a cell-free assay (IC50 = 70 nM) than MK-886 and hit compound 1, respectively. Molecular docking suggests that compound 8n could inhibit PGE2 production by blocking the PGH(2) binding site of human mPGES-1 enzyme. (C) 2015 Elsevier Ltd. All rights reserved.
