AMD-070 is a selective and oral bioavailable antagonist of chemokine receptor CXCR4 with IC50 value of 13 nM .
CXCR4 is a G-protein-coupled receptor that plays important roles in tumor development. It affects the migration, proliferation and survival of cancer cells through the CXCL12-mediated MAPK signaling. AMD-070 is an orally bioavailable antagonist of CXCR4 and is found to be an inhibitor of tumor cell migration. CXCR4 is also one of the two chemokine receptors that are used by virus for infecting human cells. As a CXCR4 inhibitor, AMD-070 can repress the replication of X4 (T-tropic) HIV-1 and the interaction of gp120/CXCR4 potently. The mechanistic studies demonstrate that AMD-070 is an allosteric inhibitor. It was found that a hydrogen bond was formed between the benzimidazole of AMD-070 and the Tyr45 residue of CXCR4 whereas the residues Asp262, Asp171 and Glu288 were not involved in the direct interactions with AMD-070 [1, 2 and 3].
AMD-070 is selective against CXCR4 over other related G-protein-coupled chemokine receptors including CXCR1, CXCR2, CCR1, CCR2b, CCR4 and CCR5. The IC50 values of AMD-070 against these GPCRs were all above 10 μM. In HOS cells expressing human CXCR4, AMD-070 inhibited HIV-1 infection with IC50 value of 10 nM. In CD4+CXCR4+T cells, AMD-070 showed anti-HIV-1 activity (IC50 value of 2 nM) through inhibiting the SDF-1 induced calcium flux with IC50 value of 12 nM. In addition, AMD-070 inhibited the competitive binding of 125I-SDF-1with IC50 value of 13 nM. In melanoma cells CHL-1 and A375, treatment of AMD-070 significantly inhibited the migration of cells. Besides that, the void sizes of cells were also increased by the inhibitor treatment [1, 2 and 4].
