Description

A cell-permeable, orally active NSAID (nonsteroidal antiinflammatory drug) that blocks cellular Cox pathway PGE2 (prostaglandin E2) production by inhibiting COX-1 and mPGES-1 (microsomal PGE2 synthase-1), but not COX-2, activity (IC50 = 8, 2, and 58 M, respectively), as well as suppresses cellular 5-LO (5-Lypoxygenase, Cat. No. 437996) pathway activation by inhibiting FLAP (5-LO-activating protein), rather than 5-LO, activity (<10% by 1 M MK-886). Unlike NSAIDs (nonsteroidal antiinflammatory drugs) that target only COX pathway, MK-886 does not cause gastrointestinal damages when applied in vivo.
