A new class of 2-substituted benzoxazole carboxamides are presented as potent functional 5-HT3 receptor antagonists. The chemical series possesses nanomolar in vitro activity against human 5-HT3A receptors. A chemistry optimization program was conducted and identified 2-aminobenzoxazoles as orally active 5-HT3 receptor antagonists with good metabolic stability. These novel analogues possess drug-like
作为有效的功能性5-HT 3受体拮抗剂,提出了一类新型的2-取代的苯并恶唑羧酰胺。该化学系列具有针对人5-HT 3 A受体的纳摩尔体外活性。进行了化学优化程序,并确定了2-氨基苯并恶唑为具有良好代谢稳定性的口服活性5-HT 3受体拮抗剂。这些新颖的类似物具有类似药物的特性,并且在治疗归因于5-HT 3受体功能异常的疾病,特别是腹泻为主的肠易激综合征(IBS-D)方面具有潜在的实用性。
