Bruton's tyrosine kinase (BTK) is a Tec family kinase with a well-defined role in the B cell receptor (BCR) pathway. It has become an attractive kinase target for selective B cell inhibition and for the treatment of B cell related diseases. We report a series of compounds based on 8-amino-imidazo[1,5-a]pyrazine that are potent reversible BTK inhibitors with excellent kinase selectivity. Selectivity
布鲁顿酪氨酸激酶(BTK)是一种Tec家族激酶,在B细胞受体(BCR)途径中具有明确的作用。它已成为用于选择性B细胞抑制和治疗B细胞相关疾病的有吸引力的激酶靶标。我们报告了一系列基于8-氨基-咪唑并[1,5-a]吡嗪的化合物,它们是有效的可逆BTK抑制剂,具有出色的激酶选择性。通过配体与激酶铰链的特异性相互作用并由氨基吡啶与Ser538和Asp539的氢键键合以及后口袋中三氟吡啶的疏水性相互作用来实现选择性。这些相互作用在与BTK酶形成复合物的先导化合物1和3的X射线晶体结构中很明显。
