  Discovery of novel prostaglandin analogs as potent and selective EP2/EP4 dual agonists

  摘要：

  To identify potent EP2/EP4 dual agonists with excellent subtype selectivity, a series of c-lactam prostaglandin E analogs bearing a 16-phenyl x-chain were synthesized and evaluated. Structural hybridization of 1 and 2, followed by more detailed chemical modification of the benzoic acid moiety, led us to the discovery of a 2-mercaptothiazole-4-carboxylic acid analog 3 as the optimal compound in the series. An isomer of this compound, the 2-mercaptothiazole-5-carboxylic acid analog 13, showed 34-fold and 13-fold less potent EP2 and EP4 receptor affinities, respectively. Structure activity relationship data from an in vitro mouse receptor binding assay are presented. Continued evaluation in an in vivo rat model of another 2-mercaptothiazole-4-carboxylic acid analog 17, optimized for sustained compound release from PLGA microspheres, demonstrated its effectiveness in a rat bone fracture-healing model following topical administration.

  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。

  A series of gamma-lactam prostaglandin E(1) analogs bearing a 16-phenyl moiety in the omega-chain and aryl moiety in the alpha-chain were synthesized and biologically evaluated. Among the tested compounds, gamma-lactam PGE analog 3 designed as a structural hybrid of 1 and 2 was discovered as the most optimized EP2/EP4 dual agonist with excellent subtype-selectivity (K(i) values: mEP2 = 9.3 nM, mEP4 = 0.41 nM). A structure-activity relationship study is presented. (C) 2011 Elsevier Ltd. All rights reserved.
