Tirabrutinib (ONO-4059) 是一种口服有效的高选择性Bruton’s Tyrosine Kinase(BTK) 抑制剂 (能透过血脑屏障)，其IC50值为 6.8 nM。Tirabrutinib 不可逆共价结合BTK并抑制异常 B 细胞受体信号传导。Tirabrutinib 可用于自身免疫性疾病和血液学恶性肿瘤的研究。
| 生物活性 | Tirabrutinib (ONO-4059) is an orally activeBruton’s Tyrosine Kinase(BTK) inhibitor (can cross the blood-brain barrier (BBB)), with anIC50of 6.8 nM. Tirabrutinib irreversibly and covalently binds toBTKand inhibits aberrant B cell receptor signaling. Tirabrutinib can be used in studies of autoimmune diseases and hematological malignancies[1][2][3][4]. |
体外研究
(In Vitro) | Tirabrutinib (0.1-1000 nM or 0.001-100 nM; 72 h) inhibits the proliferation of OCI-L Y10 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 SU-DHL-6 cells apoptosis needs high dosage and prolonged administration (concentration up to 50 μM and incubates for 48 h)[1].
Tirabrutinib (300 nM, 72 h) induces caspase-3 and PARP cleavage in TMD8 cells[2].
