We aimed to discover a novel type of transient receptor potential vanilloid 1 (TRPV1) antagonist because such antagonists are possible drug candidates for treating various disorders. We modified the structure of hit compound 7 (human TRPV1 IC50 = 411 nM) and converted its pyrrolidino group to a (hydroxyethyl)methylamino group, which substantially improved inhibitory activity (15d; human TRPV1 IC50 = 33 nM)
我们旨在发现一种新型的瞬时受体电位类香草素1(TRPV1)拮抗剂,因为此类拮抗剂可能是治疗各种疾病的候选药物。我们修改了命中化合物7(人TRPV1 IC 50 = 411 nM)的结构,并将其吡咯烷基基团转变为(羟乙基)甲基氨基,从而大大提高了抑制活性(15d;人TRPV1 IC 50 = 33 nM)。另外,15d改善了大鼠体内的膀胱过度活动。
