screened for Aurora A/B kinases inhibitory activity. Among them, 7c, 7d, 8c, and 8d are more potent against Aurora A kinase than ZM447439. Docking study of compounds 7d and ZM447439 revealed that they bound strongly to the ATP-binding sites of Aurora A and B. Thus, they may be promising lead compounds for the development of novel anti-tumor drug potentially via inhibiting Aurora kinases.
设计并合成了两个系列的20种新颖的4-氨基喹唑啉-脲衍生物。使用基于MTT的分析方法研究了全部目标化合物对六种人类癌细胞系(K562,U937,A549,NCI-H661,HT29和LoVo)的体外抗增殖活性。大多数化合物对四种实体瘤细胞系均显示出显着的抗增殖活性,但对两种白血病细胞系则无或具有较弱的活性。此外,针对目标化合物筛选了Aurora A / B激酶的抑制活性。其中7c,7d,8c和8d比ZM447439更有效地对抗Aurora A激酶。化合物7d的对接研究 ZM447439和ZM447439揭示它们与Aurora A和B的ATP结合位点牢固结合。因此,它们可能有望通过抑制Aurora激酶来开发新型抗肿瘤药物。
