Popis: | The discovery and SAR of potent, selective dioxane-fused tricyclic benz[ d ]imidazole derivatives as mPGES-1 inhibitor are herein described. Various amide modifications in this series afforded many potent mPGES-1 inhibitors, of which 17d proved to be suitable for further profiling in vivo . Compound 17d {2-((2-chloro-6-fluorophenyl)amino)- N -(3-fluoro-5-(trifluoromethyl)phenyl)-1-methyl-7,8-dihydro-1 H -[1,4]dioxino[2′,3′:3,4]benzo[1,2- d ]imidazole-5-carboxamide} exhibited excellent mPGES-1 enzyme (IC 50 : 8 nM), cell (A549 IC 50 : 16.24 nM) and human whole blood potency (IC 50 : 249.9 nM). In rodent species, 17d strongly inhibited guinea pig mPGES-1 (IC 50 : 10.79 nM), but not the rat and mouse enzyme. Furthermore 17d displayed excellent in vitro selectivity over mPGES-2, cPGES, COX-enzymes (COX-1, 2), selectivity against other prostanoid synthases, favorable hERG and CEREP panel profile. Likewise, our lead 17d demonstrated good oral pharmacokinetic profiles and good CNS B/P ratio in rat and guinea pig. Lead 17d also unveiled good efficacy in LPS-induced thermal hyperalgesia pain model with ED 50 of 36.7 mg/kg, respectively. |
