YS-121 is a dual inhibitor of Microsomal prostaglandin E2 synthase-1 (mPGES-1) [1].
Cyclooxygenases (COX-1 and COX-2) have been involved in catalyzing the formation of prostaglandins and related eicosanoids and play an essential role in the pathogenesis of breast cancer. Actions of COX-2 are mediated by prostaglandin E2 (PGE2). Microsomal PGES-1 (mPGES-1), the inducible form of PGES, has a marked affinity for coupling with COX-2. Expression of mPGES-1 has been observed in inflammatory conditions and cancers of the stomach, colon, lung, endometrium, and skin [2].
YS-121 inhibited the activity of mPGES-1 with an IC50 of 3.9 μM [1]. YS-121 also inhibited the activity of 5-LO with the IC50 of 4.1 μM [3]. YS-121 effectively inhibited PGE2 and LT synthesis in both cell free and intact cell assays. Intraperitoneal administration of YS-121 (1.5 mg/kg) reduced pleural levels of PGE2 and LTB4 while blocking exudate formation and leukocyte infiltration in carrageenan-induced rat pleurisy [4]. YS-121 (10 μM) showed minor effects on COX-1 and COX-2, inhibiting these enzymes 24.8% and 38%, respectively [1].
