    Background
    
    PF-9184 is a novel mPGES-1 inhibitor [1]. Microsomal prostaglandin E synthase-1 (mPGES-1) is an inducible terminal isomerase expressed in cytokine-sensitive brain endothelial cells. mPGES-1 functions as the central switch during immune-induced pyresis and as a target for treatment of fever and other PGE2-dependent acute phase reactions elicited by the brain [2]. mPGES-1 has been incolved in the formation of PGE2 essential for pain hypersensitivity and inflammation. Microsomal prostaglandin E synthase-1 (mPGES-1) has been involved in converting the COX product prostaglandin H2 (PGH2) into the biologically active PGE2[3]. In vitro: PF-9184 potently inhibited recombinant human mPGES-1 with an IC50 value of 16.5 ± 3.8 nM. PF-9184 showed no effect on rhCOX-1 and rhCOX-2 with >6500-fold selectivity. In rationally designed cell systems, PF-9184 inhibited PGE2 synthesis with IC50 in the range of 0.5–5 μM in serum-free cell and human whole blood cultures, while sparing the synthesis of 6-keto-PGF1α (PGF1α) and PGF2α[1]. PF-9184 showed no apparent cytotoxic effects up to 100 μM [1].
