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。
