Biochem/physiol Actions

PF-03549184 (PF-9184) is a potent inhibitor of microsomal prostaglandin E synthase-1 (mPGES-1) with an IC50 value of 16.5 nM in recombinant human mPGES-1. mPEGS-1 is the terminal enzyme that synthesizes prostaglandin E2 (PGE2) from PGH2 to PGE2 downstream of cyclooxygenase-2 (COX-2). Its expression is induced in response to pro-inflammatory mediators, similar to COX-2. Unlike the effects of COX inhibition, PF-9184 does not inhibit the production of other PGH2-derived products such as 6-keto-PGFα or PGF2α. PF-9184 inhibits PGE2 production in cell based assays with IC50 ranges from 0.5 to 5 μM. IC50 concentrations for rhCOX1 and rHCOX2 are 118 μM and 236 μM, respectively.
PGE2 is involved in inflammation and is one of the most abundant prostanoid.

Microsomal prostaglandin E synthase-1 (mPGES-1) is the terminal synthase responsible for the synthesis of the pro-tumorigenic prostaglandin E(2) (PGE(2)). mPGES-1 is overexpressed in a wide variety of cancers. Since its discovery in 1997 by Bengt Samuelsson and collaborators, the enzyme
