Compounds in a structurally novel series of substituted 10H-benzo[4,5]furo[3,2-b]indole-1-carboxylic acids and related 5,10-dihydro-indeno[1,2-b]indole-1-carboxylic acids were prepared and shown to possess potent, bladder-selective smooth muscle relaxant properties and thus are potentially useful for the treatment of urge urinary incontinence.

结构上新颖的取代10H-苯并[4,5]呋喃[3,2-b]吲哚-1-羧酸和相关的5,10-二氢茚并[1,2-b]吲哚-1-系列中的化合物制备了羧酸并显示出其具有有效的,对膀胱有选择性的平滑肌松弛特性,因此潜在地可用于治疗急迫性尿失禁。使用大鼠逼尿肌肌细胞的电生理研究表明,原型化合物7产生超极化电流的显着增加,该电流被iberiotoxin(IbTx)逆转,因此与大电导Ca(2+)激活的钾通道(BK( Ca))。
