Biological Activity for PF 04418948

PF 04418948 is a potent prostaglandin E receptor 2 antagonist (PTGER2; EP2; IC50 = 16 nM for human EP2 receptors), which displays over 2000-fold selectivity for EP2 receptors over EP1, EP3, EP4, DP1 amd CRTH2 receptors and exhibits <30% binding at a diverse panel of GPCRs and ion channels at a concentration of 10 μM. PF 04418948 inhibits PGE2-induced increases in intracellular cAMP in vitro and reverses PGE2-invoked relaxation of mouse trachea (IC50 = 2.7 nM).
