modifications were identified that improved TRPV4 activity by increasing structural rigidity and reducing the entropic energy penalty upon binding to the target protein. The new template was initially discovered as a minor regio-isomeric side product formed during routine structure–activity relationship (SAR) studies, and further optimization resulted in highly potent compounds with a novel pyrrolidine diol
通过修饰先前报道的TRPV4抑制剂(1),开发了一系列新型的吡咯烷磺酰胺瞬时受体电位香草酸4(TRPV4)拮抗剂。鉴定了几种核心结构修饰,它们通过增加结构刚度和减少与靶蛋白结合后的熵能损失而改善了TRPV4的活性。新模板最初是在常规的结构-活性关系(SAR)研究期间发现的,是次要的区域异构副产物,进一步的优化导致了具有新型吡咯烷二醇核心的高效化合物。通过对磺酰胺取代基进行SAR研究,进一步提高了药效和药代动力学性能,从而获得了优化的铅化合物GSK3395879(52)表明在体内大鼠模型中具有抑制TRPV4介导的肺水肿的能力。GSK3395879是研究TRPV4生物学的工具,也是鉴定新的心力衰竭药物的先进线索。
