Biological Activity
| ln Vitro | Similar inhibition of human, mouse, canine, and cynomolgus NaV1.7 was seen in heterologous cells; however, efficacy against rat NaV1.7 was diminished. Compared to Nav1.3, Nav1.4, Nav1.5, and Nav1.8, AM-2099 is about 100 times more selective; nevertheless, Nav1.1, Nav1.2, and Nav1.6 are less selective. AM-2099 does not show more than 50% inhibition against the broad CEREP panel (10 µM) and the 100 kinase panel (1 µM), and it has a low affinity for hERG (>30 µM). [1]. |
| ln Vivo | AM-2099 has excellent pharmacokinetic characteristics in rats and dogs. In rats, AM-2099 demonstrated low overall clearance and intermediate Vdss and half-life. In contrast, AM-2099 showed very poor clearance, low Vdss, and long half-life (18 hours) when administered to dogs. AM-2099 revealed a dosage-dependent increase in plasma exposure and a dose-dependent reduction in scratching times compared to vehicle-treated rats, with a statistically significant reduction found at the 60 mg/kg dose [1 ]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ≥ 150 mg/mL (~321.57 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.36 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 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL 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: ≥ 2.5 mg/mL (5.36 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 25.0 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.  (Please use freshly prepared in vivo formulations for optimal results.) |
