PF-9184 C화학적 특성, 용도, 생산
개요
Microsomal prostaglandin E synthase-1 (mPGES-1) converts the COX product prostaglandin H2 (PGH2; ) into the biologically active PGE2 . Like COX-2, the expression of mPGES-1 is induced in response to pro-inflammatory mediators, including LPS, IL-1β, and TNF-α. PF-9184 is a potent inhibitor of mPGES-1 (IC50 = 16.5 nM for recombinant human enzyme). It displays at least 6,500-fold selectivity for mPGES-1 over COX-1 and COX-2. PF-9184 blocks the synthesis of PGE2 in LPS-treated human whole blood and in IL-1β-stimulated fibroblasts (IC50s = 0.4-5 μM).
용도
PF 9184 is a?microsomal prostaglandin E?synthase-1(mPGES-1) inhibitor. mPGES-1is an enzyme induced during the inflammatory response and it is an attractive target for developing anti-inflammatory drugs.
효소 저해제
This potent mPGES-1 inhibitor (FW = 461.32 g/mol; CAS 1221971-47-6; Solubility: 100 mM in DMSO), also named N-[3',4'-dichloro(1,1'- biphenyl)yl]-4-hydroxy-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide), targets human and rat microsomal prostaglandin E synthase 1, with respective IC50 values of 16.5 nM and 1.08 μM, exhibiting >6500x selectivity toward mPGES-1 versus COX1 and COX2. PF-9184 inhibits IL- 1β-induced PGE2 synthesis in vitro. In inflammation and clinically relevant biological systems, mPGES-1 expression, like COX-2 expression is induced in cell context- and time-dependent manner, a behavior that is fully consistent with the kinetics of PGE2 synthesis
