tyrosine kinase (BTK) inhibitor, was approved by the FDA for treating mantle cell lymphoma (MCL). Although ibrutinib exhibited excellent antitumor activity, it was associated with certain adverse reactions, with off-target effects against EGFR, Itk and Src family kinases. Our studies yielded a novel series of substituted benzyl pyrrolopyrimidine derivatives capable of potent inhibition of BTK. Compared with
依鲁替尼是一种有效的不可逆布鲁顿酪氨酸激酶 (BTK) 抑制剂,已被 FDA 批准用于治疗套细胞淋巴瘤 (MCL)。虽然依鲁替尼表现出优异的抗肿瘤活性,但它与某些不良反应有关,对 EGFR、Itk 和 Src 家族激酶具有脱靶效应。我们的研究产生了一系列能够有效抑制 BTK 的新型取代苄基吡咯并嘧啶衍生物。与依鲁替尼相比,化合物15c对 MCL 细胞系表现出有效的 BTK 抑制活性和增强的抗增殖活性,增加了 12-24 倍,IC 50值低于 1 μM。低微摩尔剂量的15c抑制 BCR 信号通路并强烈诱导 Z138 细胞凋亡。依鲁替尼和15c在 Z138 细胞中以剂量依赖性方式诱导自噬。此外,化合物15c诱导了活性氧 (ROS) 的产生,这可能是其有效抗增殖活性的一个原因。重要的是,化合物15c显示出比依鲁替尼更高的 BTK 选择性,表明治疗 MCL 可能更安全。
