Acalabrutinib

Chemical formula: C₂₆H₂₃N₇O₂  Molecular mass: 465.517 g/mol  PubChem compound: 71226662

Active ingredient description

Acalabrutinib is a small-molecule inhibitor of BTK (Bruton’s tyrosine kinase). Acalabrutinib and its active metabolite, ACP-5862, form a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity. In nonclinical studies, acalabrutinib inhibited BTK-mediated activation of downstream signaling proteins CD86 and CD69 and inhibited malignant B-cell proliferation and tumor growth in mouse xenograft models.
