Bioactivity Comments
Compound 38 is highly potent against other Tec family kinases, and the receptor tyrosine kinases, EGFR, HER2 and HER4 [1], most likely by forming a covalent bond with a cysteine residue conserved amongst these proteins.
We have mapped Btk as this compound's primary target based on it being the intended target of the medicinal chemistry design [1], but include other equally well (and more potently) inhibited kinases in the interaction tables below.
