CP-544326 is a potent and selective prostaglandin E2 receptor agonist (EC50 = 2.8 nM) . IC50 value: 2.8 nM (EC50) Target: EP2 in vitro: CP-544326 is a novel, selective and potent EP2 agonist. CP-544326 with an IC50 for human EP2 equal to 10 nM (average of two independent experiments; 9 and 11 nM), is at least 270 times more selective for human EP2 subtype as compared with the other human EP subtypes, 1, 3, and 4. Based on the cell-based efficacy data using rat EP2-HEP293 cells, cAMP levels increased in a dose- and time-dependent manner yielding an average EC50of 1.9 nM (1.5 and 2.4 nM; from two independent experiments). In human EP2-HEK293 cells, CP-544326-mediated cAMP production yielded an EC50 of 2.8 nM (2.5 and 3.1 nM; from two independent experiments), which was similar to that observed for PGE2(EC50 = 2.6 nM).
