Birelentinib
Birelentinib (DZD8586) is an orally effective, selective, non-covalent inhibitor targeting LYN tyrosine kinase and BTK tyrosine kinase, capable of penetrating the blood-brain barrier. Birelentinib exhibits concentration-dependent antiproliferative effects in RI-1 cells and diffuse large B-cell lymphoma (DLBCL) cell lines carrying BTK resistance mutations (such as C481X, V416L, etc.). Birelentinib blocks both BTK-dependent and independent signaling of the B-cell receptor (BCR), thereby inhibiting tumor cell proliferation and inducing cell death. Birelentinib can be used in research to overcome resistance to existing covalent and non-covalent BTK inhibitors in B-cell non-Hodgkin lymphoma (B-NHL).

Biological Activity
In Western blot experiments using FARAGE cells (DLBCL), birelentinib blocked both BTK-dependent and independent signaling pathways, significantly downregulating the phosphorylation levels of p-BTK (Y223, Y551) and p-LYN[1].
Birelentinib, assessed by pBTK enzyme-linked immunosorbent assay (ELISA), showed a good correlation between its plasma concentration and the regulation of pBTK in whole blood and tumor tissue, demonstrating clear pharmacodynamic characteristics[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Birelentinib (50 mg/kg, 100 mg/kg; oral; once daily) significantly inhibits tumor growth and induces tumor regression in an animal model with intracranially implanted DLBCL tumor cells (TMD-8-Luci), demonstrating good anti-central nervous system lymphoma activity in the intracranial model, and showing a good correlation between plasma concentration and pBTK regulation in whole blood and tumor tissue[1].
Birelentinib (50 mg/kg, 100 mg/kg; oral; once daily) shows superior antitumor activity compared to Tirabrutinib 100 mg/kg in a brain tumor animal model with intracranially implanted TMD-8-Luci cells[1].
The unbound concentration ratio of Birelentinib (DZD8586) in cerebrospinal fluid to plasma (Kpuu,CSF) is 1.2 and 1.3 in rats and monkeys, respectively.

-
Animal Model:Subcutaneous tumor model induced by diffuse large B-cell lymphoma (DLBCL) cell lines[1]
-
Dosage:25 mg/kg, 50 mg/kg, 100 mg/kg
-
Administration:Administered orally once daily (qd)
-
Result:Exerted profound dose-dependent tumor growth inhibition. At doses of 50 mg/kg and above, it induced tumor regression compared with the vehicle control group. There was a good correlation between the plasma concentration of Birelentinib and the modulation of pBTK in whole blood and tumor tissue.
