For the purpose of discovering an orally available EP4 subtype-selective agonist, a series of 8-aza prostaglandin E1 (PGE1) analogs were synthesized and evaluated for their affinity for PGE2 receptor subtypes. Additionally, the structure–activity relationships of these compounds were studied. Among the tested compounds, the 8-aza PGE1 analog 6 and 8-aza-5-thiaPGE1 analog 12 had highly potent EP4 receptor affinity, good functional activity, and excellent subtype-selectivity. Furthermore, these analogs demonstrated good stability in human liver microsomes. As a result, we concluded that these two series of 8-aza PGE1 analogs could be promising chemical leads for an orally available EP4 subtype-selective agonist.
为了发现一种口服可用的EP4亚型选择性激动剂,合成并评估了一系列8-氮原子前列腺素E1(PGE1)类似物对PGE2受体亚型的亲和力。此外,还研究了这些化合物的结构-活性关系。在测试的化合物中,8-氮PGE1类似物6和8-氮-5-硫PGE1类似物12对EP4受体具有高效的亲和力、良好的功能活性和优异的亚型选择性。此外,这些类似物在人体肝微粒体中表现出良好的稳定性。因此,我们得出结论,这两系列的8-氮PGE1类似物可能是口服可用的EP4亚型选择性激动剂的有前景的化学先导物。
