AMD 3465 hexahydrobromide inhibits binding of 12G5 mAb and CXCL12AF647 to CXCR4, with IC50s of 0.75 nM and 18 nM in SupT1 cells.?AMD 3465 (50 nM) totally blocks CXCL12-induced calcium mobilization, with an IC50 of 17 nM, but shows no effect on the intracellular calcium fluxes elicited by the CCR5 ligands RANTES, LD78β and MIP-1β in U87.CD4.CCR5 cells.?AMD 3465 also potently inhibits the replication of X4 HIV strains (IC50: 1-10 nM), but has no effect on CCR5-using (R5) viruses.?AMD3465 is cytotoxic to the X4 HIV-1 strains IIIB, NL4.3, RF and HE with an IC50 ranging from 6 to 12 nM.?The IC50 for suppression of the HIV-2 strains ROD and EHO is 12.3 nM[1].?AMD 3465 inhibits CXCL-12-induced growth in U87 and Daoy cells.?AMD 3465 treatment stimulates the phosphorylation of Erk1/2 in U87 and Daoy cells[2].

AMD 3465 with 2.5 mg/kg/d, s.c. for 5 weeks significantly blocks the growth of U87 GBM and Daoy xenografts[2]
