Burixafor hydrobromide
Based on 2 publication(s) in Google Scholar
Burixafor (TG-0054) hydrobromide is a potent CXCR4 antagonist with a pIC50 of 7.4. Burixafor hydrobromide 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 hydrobromide mobilizes CD34+ hematopoietic stem/progenitor cells (HSPC) from the bone marrow to the peripheral blood. Burixafor hydrobromide can be used for research on autologous hematopoietic stem cell transplantation (ASCT).
