chemistry synthesis via CuAAC reaction followed by in situ biological screening were used to discover selective Cdc25 inhibitors. The bioassay results showed that compound M2N12 proved to be the most potent Cdc25 inhibitor, which also act as a highly selective Cdc25C inhibitor and was about 9-fold potent than that of NSC 663284. Moreover, M2N12 showed remarkable anti-growth activity against the KB-VIN cell
细胞分裂周期25(Cdc25)蛋白磷酸酶在细胞周期阶段之间的过渡中起着关键作用,其与各种癌症的关联已得到广泛证明,这使其成为抗癌治疗的理想靶标。尽管已经开发了几种Cdc25抑制剂,但大多数都显示出较低的活性和较差的亚型选择性。因此,发现对Cdc25亚型具有有效活性和显着选择性的新型小分子抑制剂非常重要,它不仅可以作为治疗癌症的药物,而且可以探索其在过渡过程中的作用机理。在这项研究中,通过CuAAC反应进行的微型平行点击化学合成,然后进行原位生物筛选,用于发现选择性的Cdc25抑制剂。生物测定结果表明,化合物M2N12被证明是最有效的Cdc25抑制剂,它也具有高选择性Cdc25C抑制剂的作用,其效力是NSC 663284的9倍。此外,M2N12对KB表现出显着的抗生长活性。 -VIN细胞系,与PXL和NSC 663284等效。采用全原子分子动力学(MD)模拟方法来探究M2N12对Cdc25C
