| Additional Infomation |
N-methylnicotinamide is a pyridinecarboxamide that is nicotinamide in which one of the amide hydrogens is substituted by a methyl group. It has a role as a metabolite. It is functionally related to a nicotinamide. N-methylnicotinamide is an experimental drug with no approved indication or marketed formulation. It is a metabolite of niacinamide/nicotinamide and niacin/nicotinic acid (vitamin B3), and as such N-methylnicotinamide is used to diagnose niacin deficiency by measuring N-methylnicotinamide in the urine. Drug Indication N-methylnicotinamide is an experimental drug with no approved indication. |
Solubility Data
| Solubility (In Vitro) | DMSO: 250 mg/mL (1836.21 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.17 mg/mL (15.94 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 21.7 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: ≥ 2.17 mg/mL (15.94 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 21.7 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: ≥ 2.17 mg/mL (15.94 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 21.7 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.) |
