Fifty-one 1,2,3-triazole derivatives were synthesized and evaluated with respect to P2X7 receptor (P2X7R) activity and its associated pore. These triazoles were screened in vitro for dye uptake assay and its cytotoxicity against mammalian cell types. Seven 1,2,3-triazole derivatives (5e, 6e, 8h, 9d, 9i, 11, and 12) potently blocked P2X7 receptor pore formation in vitro (J774.G8 cells and peritoneal
合成了五十一种1,2,3-三唑衍生物,并就P2X7受体(P2X7R)活性及其相关的孔进行了评估。对这些三唑进行了体外筛选,以进行染料吸收测定及其对哺乳动物细胞类型的细胞毒性。七个1,2,3-三唑衍生物(5e,6e,8h,9d,9i,11和12)在体外有效阻断了P2X7受体的孔形成(J774.G8细胞和腹膜巨噬细胞)。显示的所有阻断剂IC 50其值低于500 nM,并且在两种细胞类型中均具有低毒性。这七个选定的三唑抑制了P2X7R介导的白介素1(IL-1β)释放。特别是,化合物9d是最有效的P2X7R阻滞剂。另外,在小鼠的由ATP或角叉菜胶给药引起的炎症反应的小鼠急性模型中,化合物9d促进了有效的阻断反应。同样,9d也降低了小鼠LPS诱导的胸膜炎细胞性。在计算机上的预测表明,当将该分子与市售类似物进行比较时,该分子适合发展抗炎剂。电生理研究表明9d作用的竞争机制阻断P2X7受体。为了观察优先
