  Discovery of a potent and selective agonist of the prostaglandin EP4 receptor

  摘要：

  Analogues of PGE(2) wherein the hydroxycyclopentanone ring has been replaced by a lactam have been prepared and evaluated as ligands for the EP4 receptor. An optimized compound (19a) shows high potency and agonist efficacy at the EP4 receptor and is highly selective over the other seven known prostaglandin receptors. (C) 2003 Elsevier Science Ltd.

  Discovery of an 8-Aza-5-thiaProstaglandin E1 Analog as a Highly Selective EP4 Receptor Agonist

  摘要：

  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。

  Analogs 8-aza-16-aryl prostaglandin E1 (PGE1) and 8-aza-5-thia-16-arylPGE1 were synthesized and evaluated with respect to their subtype receptor affinity and EP4 agonist activity for the purposes of identifying subtype-selective EP4 agonists that demonstrate oral efficacy. Using an inhibition assay of lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-α production in rats, representative compounds were evaluated for their pharmacokinetic profiles and in vivo efficacy. Structure–activity relationships (SARs) were characterized and presented. Of the compounds tested, several demonstrated better oral exposure and/or in vivo efficacy compared with the previously reported analog 2a.
