EP4 receptor antagonist 3 is a highly potent and specific inhibitor of the EP4 receptor. It is intended for research purposes in studying EP4 receptor-mediated diseases such as acute and chronic pain, osteoarthritis, rheumatoid arthritis, and cancer.
Aganepag, a potent Prostanoid EP2 receptor agonist, exhibits remarkable selectivity with an EC50 of 0.19 nM, demonstrating no activity at the EP4 receptor. Its applications are primarily in the fields of wound healing, scar reduction, scar prevention, and the treatment and prevention of wrinkles.
L-902688 is an orally active EP4 receptor agonist (Ki: 0.38 nM; EC50: 0.6 nM). L-902688 displays >4,000-fold selective for EP4 over other EP and prostanoid receptors.
KAG-308 is an effective selective and orally active agonist of the EP4 receptor (Ki: 2.57 nM and EC50: 17 nM for human EP4 receptor), more selective over EP1, EP2, EP3, and IP receptor. KAG-308 suppresses colitis and promotes histological mucosal healing,
