A series of small‐molecule Plk1 inhibitors targeting the substrate‐binding pocket were designed through rational drug design for the first time. The designed compounds were synthesized and their activities were evaluated in vitro. Some of the targeted compounds showed potent Plk1 inhibitory activities and anti‐proliferative characters. Particularly, 5i showed Plk1 inhibitory activity with an IC50 value
首次通过合理的药物设计设计了一系列靶向底物结合口袋的小分子 Plk1 抑制剂。合成了设计的化合物并在体外评估了它们的活性。一些目标化合物显示出有效的 Plk1 抑制活性和抗增殖特性。特别是,5i 表现出 Plk1 抑制活性,IC50 值为 0.68 µM。化合物 5i 还显示出对 HeLa 细胞的细胞生长抑制活性,IC50 值为 0.51 µM,其效力是百里醌的四倍。作用机制表明 5i 是一种不依赖于 ATP 且依赖于底物的 Plk1 抑制剂。化合物 5i 对 Plk2、Plk3 和五种丝氨酸/苏氨酸和酪氨酸激酶显示出优异的 Plk1 抑制选择性。
