ono-ae3-208

ONO-AE3-208 (AE 3-208) 是一种 EP4 拮抗剂，可抑制前列腺癌的细胞迁移、侵袭和转移。

ONO-AE3-208 is an EP4 receptor antagonist with a Ki of 1.3 nM, exhibiting less potent activity against EP3, FP, and TP receptors (Ki values of 30, 790, and 2,400 nM, respectively), while showing no effect on other prostanoid receptors. In wild type mice, treatment with ONO-AE3-208, in conjunction with 3% dextran sodium sulfate, results in severe colitis characterized by epithelial loss, crypt damage, and inflammation, thereby mimicking the effects of EP4 deletion. Further, this compound has been utilized to investigate the role of EP4 signaling in various biological contexts, including immune and autoimmune responses, inflammation, and cancer.
