EP4 receptor antagonist 1 是一种有效的特异性前列腺素EP4受体拮抗剂，对人和小鼠EP4受体的IC50分别为6.1 nM和16.2 nM。 EP4 receptor antagonist 1 可用于癌症免疫治疗的研究。

EP4 receptor antagonist 1 inhibits human and mouse EP4 receptor with IC50s of 6.1 nM and 16.2 nM, respectively. IC50s >10 μM for human EP1, EP2,and EP3 receptors.EP4 receptor antagonist 1 is a highly potent and selective competitive prostanoid EP4 receptor antagonist for cancer immunotherapy.

EP4 receptor antagonist 1 inhibits the activity of the CRE reporter in HEK293 cells with an IC50 of 5.2±0.4 nM in a dose-dependent manner. EP4 receptor antagonist 1 dose-dependently inhibits PGE2-stimulated β-arrestin recruitment in HEK293-EP4 cells with an IC50 of 0.4±0.1 nM. EP4 receptor antagonist 1 inhibits PGE2-stimulated cAMP accumulation in HEK293-EP4 cells with an IC50 of 18.7±0.6 nM in a dose-dependent manner. EP4 receptor antagonist 1 (1 nM-10 μM) reverses PGE2-induced ERK phosphorylation in a concentration-dependent manner. The IC50s are >10 μM for human EP1, EP2, and EP3 receptors[1].

EP4 receptor antagonist 1 (1 mg/kg; i.v.) demonstrates moderate clearance of 1.7 L/h/kg in mice with a corresponding favorable half-life of 4.1 h. EP4 receptor antagonist 1 (5 mg/kg; orally) exhibits good bioavailability of 48.0% in mice with a corresponding favorable half-life of 4.7 h. EP4 receptor antagonist 1 (16, 50, and 150 mg/kg; oral) causes significant inhibition of tumor growth in BALB/c female mice. No significant body weight loss is found in any mouse cohorts. EP4 receptor antagonist 1 is well tolerated in mice at the tested dosage[1].
