| Targets |
H-N-Me-Ala-OH.HCl is classified as an N-methylated amino acid and does not have a specific biological receptor target. Its primary application is as a building block for introducing N-methylalanine residues into peptides. N-methylation of peptide backbones can enhance metabolic stability, improve oral bioavailability, and modulate biological activity by restricting conformational flexibility and reducing hydrogen bond donation.

| 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].
In vitro activity for H-N-Me-Ala-OH.HCl is primarily as a peptide synthesis building block. Amino acid derivatives have been commercially used as ergogenic supplements, influencing anabolic hormone secretion, fuel availability, mental performance, and prevention of muscular damage. H-N-Me-Ala-OH.HCl itself is not directly biologically active. Its utility is in preparing N-methylalanine-containing peptides for subsequent biological evaluation. |
| ln Vivo |
In vivo activity data for H-N-Me-Ala-OH.HCl as a standalone compound is not applicable. It is an N-methylated amino acid used as a research building block. Peptides synthesized using this building block may be evaluated in animal models. N-methylation can improve peptide stability, permeability, and reduce susceptibility to enzymatic degradation.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (24.24 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 (24.24 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. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
