We have designed a series of potent EP1 receptor antagonists. These antagonists are a series of 2-(1H-indazol-1-yl)-thiazoles in which the core structure was replaced with pyrazole-phenyl groups. In preliminary conscious rat cystometry experiments, two representative candidates, 2 and 22, increased bladder capacity. In particular, the increase using 22 was approximately 2-fold that of the baseline
我们设计了一系列有效的EP 1受体拮抗剂。这些拮抗剂是一系列2-(1H-吲唑-1-基)-噻唑,其中核心结构被吡唑-苯基取代。在初步的自觉大鼠膀胱测压实验中,两个有代表性的候选人2和22增加了膀胱容量。特别是,使用22的增加大约是基线的2倍。该化合物的更详细的分析以及对该系列的进一步优化有望提供一类用于治疗膀胱过度活动症(OAB)的新型药物。
