Description
Acalabrutinib (CAS 1420477-60-6) is a selective, covalent Bruton's tyrosine kinase (BTK) inhibitor with molecular formula C₂₆H₂₃N₇O₂ and MW 465.50 g/mol. It is also known as ACP-196.
Acalabrutinib is reported to irreversibly inhibit BTK by covalently binding to Cys481 within the kinase active site via its acrylamide-derived but-2-ynoyl warhead. This covalent modification blocks downstream B-cell receptor signaling pathways, including PLCγ2 activation and NF-κB nuclear translocation, thereby suppressing B-cell proliferation and survival. Its imidazo[1,5-a]pyrazine scaffold confers selectivity over a broad panel of off-target kinases relative to earlier-generation BTK inhibitors.
