product name PF-04418948


Description: PF-04418948 is a novel, potent and selective prostaglandin EP2 receptor antagonist. PF-04418948 inhibited prostaglandin E2(PGE2-induced increase in cAMP in cells expressing EP2 receptors with a functional KB value of 1.8 nM. In human myometrium, PF-04418948 produced a parallel, rightward shift of the butaprost-induced inhibition of the contractions induced by electrical field stimulation with an apparent KB of 5.4 nM. In dog bronchiole and mouse trachea, PF-04418948 produced parallel rightward shifts of the PGE2-induced relaxation curve with a KB of 2.5 nM and an apparent KB of 1.3 nM respectively. Reversal of the PGE2-induced relaxation in the mouse trachea by PF-04418948 produced an IC50 value of 2.7 nM.

In Vitro

In vitro activity: PF-04418948 antagonizes the effects of butaprost and PGE2 on an EFS-induced contraction of the human myometrium, and antagonizes PGE2-induced relaxation of carbachol pre-contracted rings of mouse trachea. PF-04418948 competitively inhibits relaxations of murine and guinea pig trachea induced by ONO-AE1-259 and PGE2 respectively. PF-04418948 restores neutrophil extracellular traps (NETs) formation in neutrophils isolated from BMT mice or HSCT patients.
