Poseltinib is an orally active, selective, irreversible small-molecule Bruton tyrosine kinase (BTK) inhibitor with an IC50 of 1.95 nM and 0.3, 2.3, and 2.4 fold selective action against BMX, TEC, and TXK, respectively. Poseltinib covalently binds to the active site of BTK (cysteine 481 residue) and effectively inhibits B cell receptor (BCR), Fc receptor (FcR), and Toll-like receptor (TLR) mediated signaling.
