Description: BL-8040, also known as BKT140 and TF 14016, is an orally bioavailable inhibitor of CXC Chemokine Receptor 4 (CXCR4) with potential antineoplastic activity. CXCR4 antagonist BKT140 selectively binds to the chemokine receptor CXCR4, preventing the binding of stromal derived factor-1 (SDF-1 or CXCL12) to the CXCR4 receptor and subsequent receptor activation, which may result in decreased tumor cell proliferation and migration. In addition, inhibition of CXCR4 may induce mobilization of hematopoietic cells from the bone marrow into blood. The G protein-coupled receptor CXCR4 plays an important role in chemotaxis and angiogenesis and is upregulated in several tumor cell types; SDF-1/CXCR4 interaction induces retention of hematopoietic cells in the bone marrow.

Additional Information

BKT140, currently being developed by Biokine,  is a highly selective inverse agonist of CXCR4, with a high affinity (0.8nM) and a low rate of dissociation from its receptor. Pre-clinical studies in animal models with BKT140 showed a robust mobilization of hematopoietic stem cells. Furthermore, BKT140 also showed a direct and indirect anti-tumor effect in vitro and in vivo against a variety of human-derived tumors, such as multiple myeloma, lymphoma, leukemia, neuroblastoma, retinoblastoma and lung cancer. BKT140 directly stimulates apoptosis (cell death) of certain types of tumors, interferes with CXCR4 mediated drug-resistance of tumor cells (CAM-DR), and enhances the therapeutic potential of anti-cancer drugs that fail to eliminate residual disease and cancer stem cells.  (source:
