  Design and synthesis of a selective EP4-receptor agonist. Part 3: 16-phenyl-5-thiaPGE1 and 9-β-halo derivatives with improved stability

  摘要：

  To identify a new selective EP4-agonist with improved chemical stability, further chemical modification of those reported previously was continued. We focused our attention on chemical modification of the alpha chain of 3,7-dithiaPGE(1), and selected 5-thiaPGE(1), as a new chemical lead, Introduction of an optimized omega to chain to the 5-thiaPG skeleton afforded in-methoxymethyl derivative 33a, which showed the most potent EP4-receptor agonist activity and good subtype-selectivity both in vitro and in vivo. 9beta-HaloPGF derivatives were also synthesized and biologically evaluated in an attempt to block self-degradation of the beta-hydroxyketone moiety. Among these series, 39a and 39b showed potent agonist activity and good subtype-selectivity. Structure-activity relationships (SARs) are also discussed. (C) 2002 Elsevier Science Ltd.

  A practical method of synthesizing it highly selective EP4-receptor agonist 1 using Corey lactone 2 as a key intermediate was developed. Selective methanesulfonylation of the primary alcohol of the diol 8 under the newly devised conditions followed by the protection of the remaining secondary alcohol are key reactions in this new method.

  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。

  improved synthesis of the highly selective EP4-receptor agonist ONO-4819 has been developed. The previous synthesis suffered from several drawbacks, in which a critical one is the difficulty in the removal of byproducts leading to unsatisfactory quality of the active pharmaceutical ingredient (API). Furthermore, on stereoselective reduction of an enone intermediate by binaphthol-modified lithium aluminum

  高度选择性的EP4-受体激动剂ONO-4819的改进合成已经被开发出来。先前的合成方法具有几个缺点，其中一个关键的问题是难以除去副产物，导致活性药物成分（API）的质量不能令人满意。此外，在通过联萘酚改性的氢化铝锂立体选择性还原烯酮中间体时，低浓度的反应条件和繁琐的纯化步骤以除去过量的联萘酚是API生产过程中的关键问题。在改进的过程中，我们开发了使用γ-硫代丁内酯代替硫代乙酸钾作为硫源的改进条件，以引入含硫的C4侧链而不会形成副产物。对于手性醇的立体选择性合成，发现（-）-DIP-氯化物还原是最好的方法，这不仅可以提高对映选择性，而且可以提高纯化过程中去除手性改性剂的工作量。此外，苯甲酰基和叔丁基二甲基甲硅烷基作为羟基官能团的保护基用于所有中间体的精确工艺控制。通过改变这些保护基团，可以通过结晶中间体严格控制ONO-4819的纯度。因此，开发了具有高化学纯度的用于ONO-4819的改进的稳健方法。
