A novel series of BTK inhibitors bearing thieno[3,2-c]pyridin-4-amine framework as the core scaffold were designed, synthesized and well characterized. In this paper, twenty one compounds displayed variant inhibitory activities against BTK in vitro, and compound 14g showed the most potent inhibitory activity against BTK enzyme, with the IC50 value of 12.8 nM. Moreover, compounds 14g displayed relatively
设计,合成和表征了一系列以噻吩并[3,2 - c ]吡啶-4-胺骨架为核心骨架的新型BTK抑制剂。在本文中,二十一种化合物在体外显示出对BTK酶的不同抑制活性,而化合物14g对BTK酶显示出最有效的抑制活性,IC 50值为12.8 nM。而且,化合物14g显示出相对良好的激酶选择性,并且随后在体内评估了其PK特性。这项工作确定了thieno [3,2 - c ] pyridin-4-amine衍生物是新型的BTK抑制剂,并验证了thieno [3,2 - c ] pyridin-4-amine支架在药物设计中的价值。
