Novel pyrazolo[1,5-a]pyridine derivatives were designed, synthesized and evaluated as orally active EP1 antagonists for the treatment of overactive bladder. Matched molecular pair analysis (MMPA) allowed the design of a new series of pyrazolo[1,5-a]pyridine derivatives 4-6. Structure-activity relationships (SAR) studies of 4-6 were performed, leading to identification of the nanomolar-level EP1 antagonist
设计,合成和评价新型吡唑并[1,5-a]吡啶衍生物作为口服活性EP1拮抗剂,用于治疗膀胱过度活动症。匹配的分子对分析(MMPA)允许设计一系列新的吡唑并[1,5-a]吡啶衍生物4-6。进行了4-6的结构-活性关系(SAR)研究,鉴定了纳摩尔水平的EP1拮抗剂4c,在17-苯基trinor前列腺素E2诱导的膀胱收缩模型中,通过十二指肠内(id)给药显示出良好的药理作用在大鼠中。
