Bruton’s tyrosine kinase (Btk) is an attractive drug target for treating several B-cell lineage cancers. Ibrutinib is a first-in-class covalent irreversible Btk inhibitor and has demonstrated impressive effects in multiple clinical trials. Herein, we present a series of novel 2,5-diaminopyrimidine covalent irreversible inhibitors of Btk. Compared with ibrutinib, these inhibitors exhibited a different
Bruton的酪氨酸激酶(Btk)是治疗几种B细胞谱系癌症的引人注目的药物靶标。依鲁替尼是一流的共价不可逆Btk抑制剂,在多项临床试验中已显示出令人印象深刻的效果。在本文中,我们介绍了一系列新型的Btk 2,5-二氨基嘧啶共价不可逆抑制剂。与依鲁替尼相比,这些抑制剂对所分析的激酶表现出不同的选择性,并具有抑制Btk活化和催化活性的双重作用模式,从而抵消了Btk的负调节回路。该系列中的两种化合物31和38,显示出对多种B细胞淋巴瘤细胞系的有效抗增殖活性,包括生发中心B细胞样弥散性大B细胞淋巴瘤(GCB-DLBCL)细胞。另外,化合物31在小鼠异种移植模型中显着阻止了肿瘤的生长。
