Biological Activity
| ln Vitro | Commercial ergot supplements have been made from amino acids and their derivatives. They affect the release of anabolic hormones, the availability of fuel for activity, the ability to think clearly under pressure, and the prevention of muscular damage brought on by exertion. They are regarded as advantageous synergistic food ingredients [1]. |

| Additional Infomation |
N-acetyl-D-methionine is an N-acetyl-D-amino acid in which the amino acid is D-methionine. It is a D-methionine derivative, a N-acetyl-D-amino acid and a N-acetylmethionine. It is a conjugate acid of a N-acetyl-D-methionine(1-). It is an enantiomer of a N-acetyl-L-methionine. N-acetyl-D-methionine is a metabolite found in or produced by Saccharomyces cerevisiae. |
Solubility Data
| Solubility (In Vitro) | DMSO: 100 mg/mL (522.88 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (13.07 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 (13.07 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. Solubility in Formulation 3: ≥ 2.5 mg/mL (13.07 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 25.0 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.) |
