MedKoo CAT#: 206603

CAS#: 1439901-97-9 (HCl)

Description: Tirabrutinib HCl, also known as ONO-4059 HCl, is a potent and orally active Bruton agammaglobulinemia tyrosine kinase (BTK) in hibitor. Upon administration, ONO-4059 covalently binds to BTK within B cells, thereby preventing B-cell receptor signaling and impeding B-cell development. As a result, this agent may inhibit the proliferation of B-cell malignancies. BTK, a cytoplasmic tyrosine kinase and member of the Tec family of kinases, plays an important role in B lymphocyte development, activation, signaling, proliferation and survival.
