KAG-308 是一种有效、选择性、可口服的 EP4 receptor (一种前列腺素 E2 受体亚型) 激动剂，抑制结肠炎，促进组织粘膜愈合，有效抑制 TNF-α 的产生。KAG-308 对人 EP4 受体的 K_i 值和 EC₅₀ 值分别为 2.57 nM 和 17 nM，对其选择性高于 EP1，EP2，EP3 和 IP 受体。

KAG-308 is a potent selective and orally active agonist of EP4 receptor (a prostaglandin E2 receptor subtype), suppresses colitis and promotes histological mucosal healing, potently inhibits TNF-α production. KAG-308 shows a K i and an EC 50 of 2.57 nM and 17 nM for human EP4 receptor, respectively, more selective over EP1, EP2, EP3 and IP receptor.

KAG-308 is a potent selective and orally active agonist of EP4 receptor, suppresses colitis and promots histological mucosal healing. KAG-308 shows a Ki and EC50 values of 2.57 nM and 17 nM for human EP4 receptor, respectively, more selective over human EP1 (Ki, 1410 nM; EC50, 1000 nM), EP2 (Ki, 1540 nM; EC50, 1000 nM), EP3 (Ki, 32.4 nM; EC50, 160 nM) and IP receptor (Ki, 52.9 nM; EC50, >10000 nM). KAG-308 also exhibits potent agonist activity for human and mouse EP4 with an EC50 of 0.15 nM and 1.0 nM, respectively in the dual luciferase reporter assay. has not independently confirmed the accuracy of these methods.
