inhibition of polo-like kinase 1 (PLK1) and BRD4 bromodomain by a single molecule could lead to the development of an effective therapeutic strategy for a variety of diseases in which PLK1 and BRD4 are implicated. Compound 23 has been found to be a potent dual kinase-bromodomain inhibitor (BRD4-BD1 IC50 = 28 nM, PLK1 IC50 = 40 nM). Compound 6 was found to be the most selective PLK1 inhibitor over BRD4
通过单个分子同时抑制 Polo 样激酶 1 (PLK1) 和 BRD4 溴结构域可能会导致开发出针对 PLK1 和 BRD4 涉及的多种疾病的有效治疗策略。化合物 23 被发现是一种有效的双激酶-溴结构域抑制剂(BRD4-BD1 IC50 = 28 nM,PLK1 IC50 = 40 nM)。发现化合物 6 是我们系列中相对于 BRD4 最具选择性的 PLK1 抑制剂(BRD4-BD1 IC50 = 2579 nM,PLK1 IC50 = 9.9 nM)。 23 和 BRD4-BD1/PLK1 以及 6 的分子对接研究证实了生化测定结果。
