Bruton's tyrosine kinase (BTK), as a key regulator of the B cell receptor (BCR) signaling pathway, is an attractive therapeutic target for the treatment of various diseases such as leukemia and B-cell malignancies. Herein, a series of compounds bearing 1, 3, 5-triazine core were prepared, and their biological activities on BTK were determined. Then the molecular docking study and ADME property prediction
作为B细胞受体(BCR)信号传导途径的关键调节剂,布鲁顿酪氨酸激酶(BTK)是治疗多种疾病(例如白血病和B细胞恶性肿瘤)的有吸引力的治疗靶标。在此,制备了一系列带有1、3、5-三嗪核心的化合物,并确定了它们对BTK的生物学活性。然后进行了分子对接研究和ADME性质预测,并发现了一种高效的选择性BTK抑制剂B8(IC50 = 21.0 nM)。化合物B8表现出优异的活性,分别具有对Raji细胞的5.14nM抑制和对Ramos细胞的6.14nM抑制。另外,B8有效抑制BTK激酶Y223自身磷酸化,使细胞周期停滞在G2 / M期并诱导Ramos细胞凋亡。BTK对BTK的高选择性和高效力在B8的TMD8细胞中显示出脱靶相关不良反应的风险低。B8上的进一步分子对接和动态模拟提供了对其在BTK中的结合情况的见解。B8在细胞分析中具有显着的功效,并且具有良好的ADME和安全性,因此可以确定B8是值得进一步分析的有前途的BTK抑制剂。
