Slingshot‐inhibiting activities have therapeutic potential against cancers or infectious diseases. However, only a few Slingshot inhibitors have been investigated and reported, and their cellular activities have not been examined. In this study, we identified two rhodanine‐scaffold‐based para‐substituted benzoic acid derivatives as competitive Slingshot inhibitors. The top compound, (Z)‐4‐((4‐((4‐oxo‐2
弹弓蛋白形成一小部分的双特异性磷酸酶,它们通过cofilin和Lim激酶(LIMK)的去磷酸化来调节细胞骨架的动力学。具有弹弓抑制活性的小型化合物具有治疗癌症或传染病的潜力。但是,仅研究和报道了几种弹弓抑制剂,尚未检查它们的细胞活性。在这项研究中,我们确定了两种基于罗丹宁骨架的对位取代苯甲酸衍生物作为竞争性弹弓抑制剂。顶部化合物(Z)-4-(((4-((4-氧代-2--2-硫代氧-3-(邻甲苯基)噻唑烷酮-5亚叉基)甲基)苯氧基)甲基)苯甲酸(D3)抑制常数(ķ我)约为4μm,并且在一组其他磷酸酶上显示出选择性。此外,化合物D3抑制神经生长因子(NGF)或血管紧张素II刺激后的细胞迁移和cofilin去磷酸化。因此,我们新近确定的弹弓抑制剂为开发以弹弓为目标的疗法提供了起点。
