Biological Activity: Burixafor (TG-0054) is a potent CXCR4 antagonist with a pIC50 of 7.4. Burixafor inhibits the binding of CXCL12 to CXCR4, antagonizes CXCL12-induced recruitment of Gαᵢ and β-arrestin2, and blocks the downstream Gαᵢ-mediated inhibitory effect on cAMP signal transduction. Burixafor mobilizes CD34+ hematopoietic stem/progenitor cells (HSPC) from the bone marrow to the peripheral blood. Burixafor can be used for research on autologous hematopoietic stem cell transplantation (ASCT)[1][2].
