  摘要：

  The preparation of a series of 1H-imidazol-1-yl-substituted benzo[b]furan-, benzo[b]thiophene-, and indolecarboxylic acids is described. Most of the compounds were potent inhibitors of TxA2 synthetase in vitro, and the distance between the imidazole and carboxylic acid groups was found to be important for optimal potency. The most potent compound in vivo was 6-(1H-imidazol-1-ylmethyl)-3-methylbenzo[b]thiophene-2-carboxylic acid (71), which, in conscious dogs, showed a similar profile of activity to that of dazoxiben (1).

• Benzo[ b ]thiophene-2-carboxamide derivatives as potent urotensin-II receptor antagonists

  Members of a series of benzo[b]thiophene-2-carboxamide derivatives, possessing an N-(1-(3-bromo-4-(piperidin-4-yloxy)benzyl)piperidin-4-yl) group, were synthesized and evaluated as urotensin-II receptor antagonists. The results show that these substances have potent UT binding affinities. Observations made in a systematic SAR investigation of the effects of a variety of substituents (R(1) and R(2))

  合成了具有N-（1-（3-溴-4-（哌啶丁-4-基氧基）苄基）哌啶丁-4-基）基团的一系列苯并[b]噻吩-2-羧酰胺衍生物，并被评估为urotensin-II受体拮抗剂。结果表明，这些物质具有有效的UT结合亲和力。在系统的SAR调查中观察到的苯并[b]噻吩-2-羧酰胺部分的5和6位上的各种取代基（R（1）和R（2））对UT结合亲和力的影响导致鉴定出5-氰基类似物7f为高效UT拮抗剂，IC50值为25nM。尽管7f具有良好的代谢稳定性，但它却是CYP同工酶的有效抑制剂，并显示出不合适的PK特性。

  日期：——

  We herein demonstrate that the combination of LiO‐tBu, CsF, and [18]crown‐6 efficiently promotes the direct C−H carboxylation of electron‐rich heteroarenes (benzothiophene, thiophene, benzofuran, and furan derivatives). A variety of functional groups, including methyl, methoxy, halo, cyano, amide, and keto moieties, are compatible with this system. The reaction proceeds via the formation of a tert‐butyl

  本文我们证明LiO-的组合吨卜，CsF和[18]冠-6有效地促进富电子杂芳烃（苯并噻吩，噻吩，苯并呋喃，和呋喃的衍生物）的直接C-H羧基化。该系统可兼容多种官能团，包括甲基，甲氧基，卤素，氰基，酰胺和酮基。反应通过形成碳酸叔丁酯物质而进行。
