PF-9184

Research use only, not for human use.

PF-9184 is a potent, selective mPGES-1 (microsomal prostaglandin E synthase-1) inhibitor with IC50 of 16.5 nM.

PF-9184 is a potent, selective mPGES-1 (microsomal prostaglandin E synthase-1) inhibitor with IC50 of 16.5 nM; shows no effect against COX-1 and COX-2 (>6,500-fold selectivity); inhibits PGE2 synthesis in serum-free cell and human whole blood cultures with IC50 of 0.5-5 uM, while sparing the synthesis of PGF(1alpha)) and PGF(2alpha).

PF-9184 (0.015-100 μM; 24 hours) inhibits IL-1β-stimulated prostaglandin E2 (PGE2) synthesis in rheumatoid arthritis (RASF) in synovial fibroblasts derived from patients and has no apparent cytotoxic effects up to 100 μM.PF-9184 (0.015-100 μM) potently blocks mPGES-1 ability to synthesize PGE2 from PGH2, and with no apparent inhibitory effects on COX-2 and prostacyclin synthase in cells.PF-9184 (0.015-100 μM) inhibits PGE2 weakly but has no effect on TXB2 synthesis except at 100 μM in human whole blood and modified blood assays.PF-9184 is a poor inhibitor of recombinant rat mPGES-1 (IC50=1080±398 nM).

PF-9184 (oral administration or even local delivery) has no effect on PGE2 synthesis in recombinant rats.
