BRD4 plays a key role in transcriptional regulation. Recent biological and pharmacological studies have demonstrated that bromodomain-containing protein 4 (BRD4) is a viable drug target for cancer treatment. In this study, we synthesized a series of dihydroquinoxalinone derivatives and evaluated their BRD4 inhibitory activities, obtaining compound 5i with IC50 value of 73nM of binding activity in BRD4(1)
BR
D4在转录调控中起关键作用。最近的
生物学和药理研究表明,含
溴结构域的蛋白质4(BR
D4)是治疗癌症的可行药物靶标。在这项研究中,我们合成了一系列二氢
喹喔啉酮衍
生物并评估了其BR
D4抑制活性,获得化合物5i,其IC50值为BR
D4(1)的结合活性为73nM,而MV-4-11癌
细胞系的细胞活性为258nM。进行了对接研究以解释结构-活性关系。基于其强大的生化和抗增殖活性,新型BR
D4抑制剂化合物5i是有希望的进一步研究的先导化合物。
