member 5 (TRPC5) helps regulate a tight balance of cytoskeletal dynamics in podocytes and is suggested to be involved in the pathogenesis of proteinuric kidney diseases, such as focal segmental glomerulosclerosis (FSGS). As such, protection of podocytes by inhibition of TRPC5 mediated Ca2+ signaling may provide a novel therapeutic approach for the treatment of proteinuric kidney diseases. Herein, we
非选择性的Ca 2+渗透性瞬时受体电势(TRP)通道在多种细胞过程中发挥重要作用,包括肌动蛋白重塑和细胞迁移。TRP通道亚家族C,成员5(TRPC5)有助于调节足细胞中细胞骨架动态的紧密平衡,并建议其参与蛋白尿性肾脏疾病(如局灶性节段性肾小球硬化(FSGS))的发病机理。这样,通过抑制TRPC5介导的Ca 2+信号传导来保护足细胞可能为蛋白尿性肾脏疾病的治疗提供一种新颖的治疗方法。在这里,我们描述了通过高通量筛选命中的哒嗪酮1的系统优化对新型TRPC5抑制剂GFB-8438的鉴定。 。GFB-8438在体外保护小鼠足细胞免受硫酸鱼精蛋白(PS)诱导的伤害。它对FSGS的高血压醋酸脱氧皮质酮(DOCA)-盐大鼠模型也有效,可显着降低尿液中的总蛋白和白蛋白浓度。
