A series of novel 4,5,6-trisubstituted pyrimidines were designed as potent covalent Bruton’s tyrosine kinase (BTK) inhibitors based on the structure of ibrutinib by using a ring-opening strategy. Among these derivatives, compound I1 exhibited the most potent inhibitory activity with an IC50 value of 0.07 μM. The preliminary structure–activity relationship was discussed and the primary amino group at
通过使用开环策略,基于依鲁替尼的结构,设计了一系列新颖的4,5,6-三取代嘧啶作为强效共价布鲁顿酪氨酸激酶(BTK)抑制剂。在这些衍生物中,化合物I 1表现出最强的抑制活性,IC 50值为0.07μM。讨论了初步的结构活性关系,嘧啶C-4位的伯氨基对于维持BTK活性至关重要。此外,对三种抑制剂-BTK配合物进行了分子动力学模拟和结合自由能计算,以确定可能的结合模型,这为进一步的结构修饰和优化提供了全面的指南。
