Tirabrutinib (GS-4059) (ONO-4059) is an orally active Bruton’s Tyrosine Kinase (Btk) inhibitor (can cross the blood-brain barrier (BBB)), with an IC50 of 6.8 nM. Tirabrutinib irreversibly and covalently binds to Btk and inhibits aberrant B cell receptor signaling. Tirabrutinib can be used in studies of autoimmune diseases and hematological malignancies.

Description | Tirabrutinib (GS-4059) (ONO-4059) is an orally active Bruton’s Tyrosine Kinase (Btk) inhibitor (can cross the blood-brain barrier (BBB)), with an IC50 of 6.8 nM. Tirabrutinib irreversibly and covalently binds to Btk and inhibits aberrant B cell receptor signaling. Tirabrutinib can be used in studies of autoimmune diseases and hematological malignancies. |
Targets&IC50 | BTK:2.2 nM |
In vitro | Tirabrutinib (0.1-1000 nM or 0.001-100 nM; 72 h) inhibits the proliferation of OCI-LY10 and SU-DHL-6 cells with IC50s of 9.127 nM and 17.10 nM, respectively[1]. Tirabrutinib (0.5, 5, 50 μM; 24, 48 h) induces apoptosis in SU-DHL-6 cells, requiring high dosage and prolonged administration (up to 50 μM for 48 h)[1]. Tirabrutinib (300 nM, 72 h) induces caspase-3 and PARP cleavage in TMD8 cells[2]. |
In vivo | Tirabrutinib (10 mg/kg; p.o.; single) is rapidly absorbed into plasma and brain, reaching Cmax (blood Cmax = 339.53 ng/mL; brain Cmax = 28.9 ng/mL) 2 hours post-administration[1]. Additionally, Tirabrutinib (6, 20 mg/kg; p.o.; single daily for 3 weeks) inhibits tumor growth in vivo[2]. |
