YS121

Description

Microsomal prostaglandin E₂ synthase-1 (mPGES-1), with cyclooxygenase-2 (COX-2), synthesizes PGE₂, which is directly involved in signaling during inflammation, fever, and pain. 5-Lipoxygenase (5-LO) initiates the synthesis of leukotrienes (LTs), which are pro-inflammatory mediators. YS-121 is a dual inhibitor of mPGES-1 (IC₅₀ = 3.9 μM) and 5-LO (IC₅₀ = 4.1 μM). It effectively inhibits PGE₂ and LT synthesis in both cell free and intact cell assays. Moreover, YS-121 (1.5 mg/kg, intraperitoneal) reduced pleural levels of PGE₂ and LTB₄ while blocking exudate formation and leukocyte infiltration in carrageenan-induced rat pleurisy. YS-121 has minor effects on COX-1 and COX-2, inhibiting these enzymes 24.8% and 38%, respectively, at 10 μM.
