  Structure–activity relationships of substituted oxyoxalamides as inhibitors of the human soluble epoxide hydrolase

  摘要：

  We explored both structure-activity relationships among substituted oxyoxalamides used as the primary pharmacophore of inhibitors of the human sEH and as a secondary pharmacophore to improve water solubility of inhibitors. When the oxyoxalamide function was modified with a variety of alkyls or substituted alkyls, compound 6 with a 2-adamantyl group and a benzyl group was found to be a potent sEH inhibitor, suggesting that the substituted oxyoxalamide function is a promising primary pharmacophore for the human sEH, and compound 6 can be a novel lead structure for the development of further improved oxyoxalamide or other related derivatives. In addition, introduction of substituted oxyoxalamide to inhibitors with an amide or urea primary pharmacophore produced significant improvements in inhibition potency and water solubility. In particular, the N,N,O-trimethyloxyoxalamide group in amide or urea inhibitors (26 and 31) was most effective among those tested for both inhibition and solubility. The results indicate that substituted oxyoxalamide function incorporated into amide or urea inhibitors is a useful secondary pharmacophore, and the resulting structures will be an important basis for the development of bioavailable sEH inhibitors.

  Insertion of isocyanides into the N–H bond gives access to many medicinally important and structurally diverse complex nitrogen-containing heterocycles. Although the transition metal catalyzed isocyanide insertion into the N–H bond is very common, polymerization of isocyanides in the presence of a transition metal and their strong coordination with metals are the common drawbacks. On the other hand

  将异氰酸酯插入到N–H键中可访问许多具有医学重要性且结构多样的复杂含氮杂环。尽管过渡金属催化的异氰酸酯插入到N–H键中非常普遍，但是在过渡金属存在下异氰酸酯的聚合以及它们与金属的强配位是常见的缺点。另一方面，在没有金属催化剂的情况下，大多数异氰酸酯对胺的惰性阻碍了将异氰酸酯插入胺中的无金属方法的发展。结果，只有少数几种金属催化方法具有有限的底物范围，可以用于通过尿素合成尿素。异氰酸酯插入胺中，尚无无金属的报道。有趣的是，文献中尚未报道将化学选择性异氰化物插入胺中。我们使用I 2 -DMSO试剂系统进行尿素的化学选择性合成，其中异氰酸酯仅与脂肪胺反应，而芳香胺则需要亲核活化剂（DABCO）来促进尿素的形成。通过避开常用但有毒的异氰酸酯，该方法可直接和化学选择性地接近尿素。
