MF63

Cat No.
CEI-1420
Product Overview
MF63 is a potent, selective and orally active mPGES-1 inhibitor. Microsomal prostaglandin E synthase-1 (mPGES-1) is a terminal prostaglandin E2 synthase in the cyclooxygenase pathway. Thus, inhibitors of mPGES-1 may block prostaglandin E2 production and relieve inflammatory symptoms.

In vitro
MF63 was found to be significantly more potent than those previously reported mPGES-1 inhibitors with an intrinsic inhibitory potency on the recombinant human mPGES-1 enzyme. Furthermore, MF63 showed a PGE2 whole cell inhibition in A549 cells and a human whole bloodactivity.
In vivo
In rodent species, MF63 inhibited guinea pig mPGES-1 strongly but not the mouse or rat enzyme. When tested in the guinea pig and a knock-in (KI) mouse expressing human mPGES-1, MF63 suppressed the synthesis of PGE2 selectively, but not other prostaglandins that were inhibitable by nonsteroidal anti-inflammatory drugs (NSAID), yet remaided NSAID-like efficacy at inhibiting lipopolysaccharide-induced hyperalgesia, pyresis, and iodoacetate-induced osteoarthritic pain. Additionally, MF63 did not cause NSAID-like gastrointestinal toxic effects, such as mucosal erosions or leakage in the KI mice or nonhuman primates, although MF63 markedly inhibited PGE2 synthesis in the KI mouse stomach.
