SHR5428 was discovered as a selective and noncovalent CDK7 inhibitor with highly potent CDK7 enzymatic activity and triple negative breast cancer cellular activity on MDA-MB-468 cell. SHR5428 also displayed favorable pharmacokinetic properties in different preclinical species such as mouse, rat and dog, and showed high selectivity over CDK1, CDK2, CDK4, CDK6, CDK9, CDK12 in CDK family. Furthermore,
细胞周期蛋白依赖性激酶 7 (CDK7)通过调节细胞周期和转录而成为肿瘤适应症的一个有吸引力的靶点。在此,SHR5428 被发现是一种选择性非共价 CDK7 抑制剂,对 MDA-MB-468 细胞具有高效的 CDK7 酶活性和三阴性乳腺癌细胞活性。SHR5428还在小鼠、大鼠和狗等不同临床前物种中表现出良好的药代动力学特性,并且对CDK家族中的CDK1、CDK2、CDK4、CDK6、CDK9、CDK12表现出高选择性。此外,计算模型也揭示了这种机制。此外,在乳腺癌细胞系(HCC70 细胞)衍生的异种移植小鼠模型中进行的体内功效研究证明,SHR5428 口服有效,具有剂量依赖性肿瘤生长抑制作用。
