QSAR study was carried out according to the in vitro activities data against CDK4/6, and two compounds 7c and 7p with potent inhibitory activities were found to interact with CDK4 in different binding conformation. They showed potential inhibition of cell proliferation against the breast cancer cell, and 7c exhibited promised anti-breast cancer effect in vivo.
CDK4/6是治疗恶性肿瘤的有吸引力的化疗靶点,CDK4/6选择性抑制剂在乳腺癌治疗中做出了突出贡献。然而,这些抑制剂具有单一的N- (pyridin-2-yl) pyrimidin-2-amine骨架,无法克服临床应用中的副作用。在我们之前的研究中,通过分析 CDK6 的活性位点特征,将一个N'-乙酰基吡咯烷-1-碳酰肼作为初始片段命中。通过片段生长法获得了两个系列的N- (pyridin-3-yl)脯氨酸。根据针对 CDK4/6 和两种化合物7c和7p的体外活性数据进行 QSAR 研究发现具有有效抑制活性的CDK4以不同的结合构象与CDK4相互作用。它们显示出对乳腺癌细胞增殖的潜在抑制作用,并且7c在体内表现出有希望的抗乳腺癌作用。
