| Bioactivity | Balixafortide TFA (POL6326 TFA) is a potent, selective, well-tolerated peptidic CXCR4 antagonist with an IC50 < 10 nM. Balixafortide TFA shows 1000-fold selective for CXCR4 than a large panel of receptors including CXCR7. Balixafortide TFA blocks β-arrestin recruitment and calcium flux with IC50s < 10 nM. Balixafortide TFA is also a potent hematopoietic stem and progenitor cell (HSPC) mobilizing agent. Anti-cancer effects[1][2]. | ||||||
| Invitro | Balixafortide potently inhibits pERK / pAKT signaling in the lymphoma lines Namalwa (IC50< 200 nM) and Jurkat (IC50 < 400 nM). Balixafortide efficiently blocks SDF-1 dependent chemotaxis of MDA MB 231 breast cancer cells (IC50 < 20 nM), Namalwa and Jurkat cells (IC50 < 10 nM)[1]. | ||||||
