8-Amino-imidazo[1,5-a]pyrazine-based Bruton’s tyrosinekinase (BTK) inhibitors, such as 6, exhibited potent inhibition of BTK but required improvements in both kinase and hERG selectivity (Liu et al., 2016; Gao et al., 2017). In an effort to maintain the inhibitoryactivity of these analogs and improve their selectivity profiles, we carried out SAR exploration of groups at the 3-position of pyrazine
基于8-氨基咪唑并[1,5- a ]吡嗪的Bruton酪氨酸激酶(BTK)抑制剂(例如6)表现出对BTK的有效抑制作用,但需要改善激酶和hERG的选择性(Liu等人,2016; Gao等人,2017)。为了维持这些类似物的抑制活性并改善其选择性,我们对吡嗪化合物6的3位进行了SAR勘探。这项工作导致发现了吗啉类作为一种优化的药效团。化合物13,23和38表现出优异的BTK效力,激酶和hERG的选择性和药代动力学曲线。

We report the design and synthesis of a series of novel Bruton's Tyrosine Kinase (BTK) inhibitors with a carboxylic acid moiety in the ribose pocket. This series of compounds has demonstrated much improved off-target selectivities including adenosine uptake (AdU) inhibition compared to the piperidine amide series. Optimization of the initial lead compound 4 based on BTK enzyme inhibition, and human
