prognosis. Thus, inhibiting CDC25 activity in cancer treatment appears a good therapeutic strategy. In this article, refinement of the initial hit XDW-1 by synthesis and screening of a focused compound library led to the identification of a novel set of imidazopyridine derivatives as potent CDC25 inhibitors. Among them, the most potent molecule was CHEQ-2, which could efficiently inhibit the activities
细胞分裂周期(CDC)25蛋白是通过与CDK /细胞周期蛋白复合物相互作用调节细胞周期过渡和增殖的关键磷酸酶。CDC25蛋白的过表达在癌症中经常被观察到,并且与侵略性,高级别肿瘤和不良预后有关。因此,在癌症治疗中抑制CDC25活性似乎是一种很好的治疗策略。在本文中,通过合成和筛选聚焦的化合物文库对最初命中的XDW-1进行了优化,从而鉴定出一套新的咪唑并吡啶衍生物作为有效的CDC25抑制剂。其中最有效的分子是CHEQ-2,它可以在体外有效抑制CDC25A / B酶的活性以及各种不同类型癌细胞的增殖。分析。此外,CHEQ-2触发了MCF-7,HepG2和HT-29细胞系的S期细胞周期停滞,并伴有ROS的产生,线粒体功能障碍和凋亡。此外,口服CHEQ-2(10 mg / kg)可显着抑制裸鼠体内异种移植的人肝肿瘤的生长,同时显示出极低的毒性(LD 50 > 2000 mg / kg)。这些发现
