Description: MF-63 is a novel and selective mPGES-1 inhibitor. MF63 potently inhibited the human mPGES-1 enzyme (IC(50) = 1.3 nM), with a high degree (>1000-fold) of selectivity over other prostanoid synthases. In rodent species, MF63 strongly inhibited guinea pig mPGES-1 (IC(50) = 0.9 nM) but not the mouse or rat enzyme. MF63 did not cause NSAID-like gastrointestinal toxic effects, such as mucosal erosions or leakage in the KI mice or nonhuman primates, although it markedly inhibited PGE(2) synthesis in the KI mouse stomach.

Additional Information

Microsomal prostaglandin E synthase-1 (mPGES-1) is a terminal prostaglandin E(2) (PGE(2)) synthase in the cyclooxygenase pathway. Inhibitors of mPGES-1 may block PGE(2) production and relieve inflammatory symptoms.
