描述了大麻素受体2(CB2)系统可调节各种病理状况,包括炎症和纤维化。从高通量筛选中鉴定出一系列新的杂环小分子CB2受体激动剂。铅优化使人们能够获得新颖,高效和选择性(超过CB1)的三唑并嘧啶衍生物。建立了初步的结构-活性关系,并且该化合物类别的理化性质朝着更好的溶解性,亲脂性和微粒体稳定性显着改善。一种优化的三唑并嘧啶衍生物,(3 S)-1- [5-叔丁基-3-[(1-环丙基四唑-5-基)甲基]三唑并[4,5 - d ]嘧啶-7-基]吡咯烷酮-3 ‐ol(39)在肾脏缺血再灌注模型中进行了测试,该模型在10 mg kg -1(po)的剂量下显示出疗效。三种检测到的肾脏标志物的显着耗竭表明CB2受体激活对炎症性肾脏损害具有保护作用。化合物39在肾纤维化模型中也是保护性的。每天口服39 mg,3 mg kg -1的口服药物,可将由单侧输尿管阻塞引起的纤维化量显着降低约40%。
