mPGES-1-IN-2 (compound III) is a benzimidazole-based mPGES-1 inhibitor that also inhibits adipophysin PGD synthase (I-PGDS) (5 μM, IR=60 %). mPGES-1-IN-2 reduces PGE2 production and tends to reduce levels of other prostaglandins. mPGES-1-IN-2 effectively inhibits acute inflammation in an air sac model stimulated by Carrageenan (HY-125474) in mice^[1].
