Discovery of thieno[3,2-c]pyridin-4-amines as novel Bruton’s tyrosine kinase (BTK) inhibitors

Add time:08/29/2019    Source:sciencedirect.com

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 good kinase selectivity and was subsequently evaluated in vivo for profiling its PK properties. This work identified the thieno[3,2-c]pyridin-4-amine derivatives as novel BTK inhibitors and verified the value of thieno[3,2-c]pyridin-4-amine scaffold in drug design.
