Plerixafor (AMD 3100) is a selective CXCR4 antagonist with an IC₅₀ of 44 nM. Plerixafor, an immunostimulant and a hematopoietic stem cell (HSC) mobilizer, is an allosteric agonist of CXCR7. Plerixafor inhibits HIV-1 and HIV-2 replication with an EC₅₀ of 1-10 nM^{[1][2][3][4][7]}.

The CXCR4 inhibitor Plerixafor (AMD3100) is a potent inhibitor of CXCL12-mediated chemotaxis (IC₅₀, 5.7 nM) with a potency slightly better than its affinity for CXCR4. Plerixafor interferes with the interaction of CXCR4 with its natural ligand, SDF-1 (CXCL12). Treating the cells with CCX771 or CXCL11 has no effect on CXCL12-mediated MOLT-4 or U937 TEM. In contrast, 10 μM Plerixafor inhibits CXCL12-mediated TEM in both cells lines^[1]
. Plerixafor prevents the infiltration of tumor-associated macrophages (TAMs) into the tumor tissues^[8].

Plerixafor (2 mg/kg) administration to UUO mice exacerbates renal interstitial T cell infiltration, resulting in increased production of the pro-inflammatory cytokines IL-6 and IFN-γ and decreased expression of the anti-inflammatory cytokine IL-10^[5].
Both perivascular and interstitial fibrosis are significantly reduced by the CXCR4 antagonist, Plerixafor (AMD3100) at 8 weeks^[6]. LD50, mouse, SC: 16.3 mg/kg; LD50, rat, SC: >50 mg/kg; LD50, mouse and rat, IV injection: 5.2 mg/kg.

U87MG cells are seeded in 96-well plates at the density of 6×10³ cells in 200 μL/well and treated with CXCL12, Plerixafor or with peptide R. MTT (5 μg/mL) is added at each time point (24, 48, 72 h) during the final 2 h of treatment. After removing cell medium, 100 μL DMSO are added and optical densities measured at 595 nm with a LT-4000MS Microplate Reader. Measurements are made in triplicates from three independent experiments^[2].

Mice^[3]
Male C57bl/6 mice (6-7 weeks old, weighing 20 g) are used. The animals are acclimated to the housing environment, which is SPF and had a temperature of 22°C and a 12h/12h light/dark cycle for a week. Then, they are randomly divided into following experimental groups, with 8 mice in each group: normal (no specific intervention), UUO+AMD3100 (mice received UUO surgery and 2 mg/kg AMD3100), and UUO+PBS (mice received UUO surgery and the same volume of PBS). AMD3100 and PBS are administered via intraperitoneal injection every day until sacrifice.
Rats^[4]
The CXCR4 antagonist, AMD3100 dissolved in H₂O, is delivered in the type 2 diabetic sand rat model at a dose of 6 mg/kg per day for 8 weeks. In complementary studies, the effect of CXCR4 antagonism (AMD3100 6mg/kg/d) on regulatory T cell numbers is examined. For these studies, AMD3100 or vehicle is delivered via minipump for a period of one week.
