Birelentinib

**Semantic type:** Pharmacologic Substance

**Definition:** An orally bioavailable non-covalent dual inhibitor of tyrosine-protein kinases Lyn (LYN) and BTK (Bruton's tyrosine kinase; Bruton agammaglobulinemia tyrosine kinase), with potential antineoplastic activity. Upon oral administration, birelentinib targets and inhibits both LYN and BTK, thereby blocking both BTK-dependent and BTK-independent B-cell antigen receptor (BCR) signaling pathways. This prevents the proliferation of malignant B-cells in which the BCR signaling pathway is overactivated. Birelentinib is able to cross the blood-brain barrier (BBB) and thus potentially useful in the treatment of central nervous system (CNS) metastases.

**Synonyms:** - BCR Signaling Pathway Inhibitor DZD8586 - BIRELENTINIB - DZD 8586 - DZD-8586 - DZD8586
