The kinesin spindle protein (KSP) is involved in the formation of bipolar mitotic spindle during cell division and it becomes a new target to overcome the neurotoxicity of MTs inhibitors. A series of flavone and isoflavone derivatives (1a–7c) have been designed, synthesized and evaluated as potential KSP inhibitors. Among them, 2c displayed the most potent inhibitory activity in vitro, which inhibited
驱动蛋白纺锤体蛋白(KSP)参与细胞分裂过程中双极有丝分裂纺锤体的形成,它成为克服MTs抑制剂的神经毒性的新目标。已经设计,合成和评估了一系列黄酮和异黄酮衍生物(1a – 7c)作为潜在的KSP抑制剂。其中2c在体外表现出最强的抑制活性,抑制MCF-7和Hela细胞系的生长,IC 50值分别为4.8和4.3μM,并且还表现出显着的KSP抑制活性(IC 50 = 0.023μM)。新化合物可以诱导不规则的单星形纺锤体,这是KSP抑制剂的特征表型。进一步进行对接仿真以确定可能的结合模型。
