ep1-antagonist-1

EP1-antagonist-1 (EP1 antagonist 1) is an EP1 antagonist (pKi: 7.54; pIC50: 8.5).

EP4 Receptor Antagonist 1 is a highly potent and selective competitive prostanoid EP4 receptor antagonist, effective for cancer immunotherapy. It inhibits both human and mouse EP4 receptors with IC50 values of 6.1 nM and 16.2 nM, respectively, while displaying minimal activity (IC50s >10 μM) against human EP1, EP2, and EP3 receptors.

GSK-269984A is an antagonist of Prostaglandin E2 Receptor 1 (EP1) (pIC50: 7.9).

BW A868C, a hydantoin compound and structural analogue of BW245C, functions as a selective and potent competitive antagonist of prostaglandin D2 (PGD2), showing no activity on other prostaglandin receptors (IP, EP1, EP2, TP, and FP) [1].

ONO-8711 is a potent and selective competitive antagonist of the EP1 receptor, with Ki values of 0.6 nM for human EP1 and 1.7 nM for mouse EP1. It effectively reduces tumor incidence and multiplicity in mouse models of colon, breast, and oral cancer [1].
