Mavorixafor trihydrochloride (AMD-070 trihydrochloride) is a potent, selective and orally available CXCR4 antagonist, with an IC50 value of 13 nM against CXCR4 125I-SDF binding, and also inhibits the replication of T-tropic HIV-1 (NL4.3 strain) in MT-4 cells and PBMCs with an IC50 of 1 and 9 nM, respectively. 125I-SDF-CXCR4|13 nM (IC50)|HIV-1 (NL4.3 strain)|1 nM (IC50, in MT-4 cells)|HIV-1 (NL4.3 strain)|9 nM (IC50, in PBMCs)|HIV-1 (NL4.3 strain)|3 nM (IC90, in MT-4 cells)|HIV-1 (NL4.3 strain)|26 nM (IC90, in PBMCs)

Mavorixafor (AMD-070) is a potent and orally available CXCR4 antagonist, with an IC50 value of 13 nM against CXCR4 125I-SDF binding, and also inhibits the replication of T-tropic HIV-1 (NL4.3 strain) in MT-4 cells and PBMCs with an IC50 of 1 and 9 nM, respectively. Mavorixafor (AMD-070) shows no effect on other chemokine receptors (CCR1, CCR2b, CCR4, CCR5, CXCR1, and CXCR2)[1]. Mavorixafor (AMD-070) (6.6 µM) significantly suppresses the anchorage-dependent growth, the migration and matrigel invasion of the B88-SDF-1 cells[2].

Mavorixafor (AMD-070) (2 mg/kg, p.o.) significantly reduces the number of metastatic lung nodules in mice, and lowers the expression of human Alu DNA in mice, without body weight loss[2].
