| ln Vitro | Aplaviroc exhibits strong efficacy against three wild-type R5 HIV-1 strains: HIV-1Ba-L, HIV-1JRFL, and HIV-1MOKW, With IC50 values ranging from 0.1 to 0.4 nM. Two previously reported CCR5 inhibitors, E921/TAK-779 and AK671/SCH-C, are significantly less potent than apiverroc. In two HIV-1MDR variants, HIV-1MM and HIV-1JSL, apivirofoc inhibits replication and infectivity at incredibly low concentrations (IC50 values of 0.4 to 0.6 nM). High affinity binding of plaviroc occurs with CCR5. Kd values for Aplaviroc, E913, E921/TAK-779, and AK671/SCH-C are 2.9±1.0, 111.7±3.5, 32.2±9.6, and 16.0±1.5 nM, respectively, based on the results calculated. At a 2.7 nM IC50, apivermico effectively inhibits the binding of rgp120/sCD4 to CCR5. These findings imply that the strong action of Aplaviroc against R5 HIV-1 originates from its highly selective binding to ECL2B and/or its surrounding regions, which inhibits gp120/CD4 binding to CCR5[1]. |
| ln Vivo |
Aplaviroc (AK602, 60 mg/kg, bid, daily) suppresses R5 HIV-1 viremia in hu-PBMC-NOG mice[2]. Immediately following intraperitoneal administration, the concentration of Aplaviroc (AK602) reached its maximum concentration and rapidly declined[2]. |
| Animal Protocol |
hu-PBMC-NOG mice 60 mg/kg Single intraperitoneal administration, bid, daily |

Solubility Data
| Solubility (In Vitro) |
DMSO: ~200 mg/mL (~325.6 mM) H2O: < 0.1 mg/mL |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 12.5 mg/mL (20.35 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 125.0 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 12.5 mg/mL (20.35 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 125.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 12.5 mg/mL (20.35 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 125.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
