  摘要：

  合成了新型的5,6-稠合杂芳族脲，并评估了它们作为TRPV1拮抗剂的活性。发现4-氨基吲哚和吲唑是连接尿素的优先核心。尿素取代基芳环对位的庞大的吸电子基团在TRPV1上具有最佳的体外效能。在体内炎症性和神经性疼痛模型中评估了最有效的衍生物。含有吲唑核心和通过尿素连接基附加到其上的3，4-二氯苯基的化合物46在口服给药时表现出体内止痛活性。在CEREP筛选中，该衍生物还显示出相对于其他受体的选择性，并且在超过治疗剂量的水平上显示出可接受的心血管安全性。

  Novel 5,6-fused heteroaromatic ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that 4-aminoindoles and indazoles are the preferential cores for the attachment of ureas. Bulky electron-withdrawing groups in the para-position of the aromatic ring of the urea substituents imparted the best in vitro potency at TRPV1. The most potent derivatives were assessed in
