guinea pigs (59.4% at 0.3 mg/kg iv and 62.8% at 3 mg/kg id). Furthermore, the effect of 3g on bladder function appeared to differ from that of tolterodine, another classical anti-pollakiuria agent, as determined by the distention-induced rhythmic bladder contraction assay using a urethane-anesthetized guinea pig model. Compound 3g is expected to be a promising agent for the treatment of urinary incontinence
制备了一系列新颖的双环嘧啶衍生物,作为寻找旨在治疗尿失禁的NK1拮抗剂的一部分。其中3g,带有4-乙酰基哌嗪基和2-甲基苯基的嘧啶并[4,5-b] [1,5]恶唑啉衍生物,显示出有效的NK1拮抗剂活性,其K(B)值为为0.105 nM,显着增加了豚鼠的有效膀胱容量(0.3 mg / kg iv时为59.4%,id 3 mg / kg时为62.8%)。此外,使用尿烷麻醉的豚鼠模型,通过扩张诱导的节律性膀胱收缩试验确定了3g对膀胱功能的影响似乎与另一种经典的抗尿蛋白尿症托特罗定不同。化合物3g有望成为治疗尿失禁的有前途的药物。
