Product Description
N-Methyl-L-valine is a valine analogue.
N-Methyl-L-valine (CAS#: 2480-23-1) is a modified version of the amino acid L-valine, where a methyl group is added to the nitrogen atom of the amino group. This compound is a valine analogue with a molecular formula of C₆H₁₃NO₂ and a molecular weight of 131.17 g/mol. The N-methylation enhances the compound's hydrophobic interaction potential and introduces specific structural changes that can affect protein folding, function, or stability. N-Methyl-L-valine is used in peptide synthesis and protein engineering to investigate how methylation influences peptide conformation and biological activity. It is also available as a hydrochloride salt for enhanced solubility. The compound is intended for research use only.
Biological Activity I Assay Protocols (From Reference)
Targets
As a valine analogue and N-methylated amino acid derivative, N-Methyl-L-valine does not have a defined primary biological target as a standalone compound. Its primary role is as a building block in peptide synthesis and protein engineering. When incorporated into peptides, N-methylation can significantly alter the biological activity, receptor binding affinity, and metabolic stability of the resulting peptide by introducing steric constraints and modifying hydrogen bonding capabilities. The methyl group on the nitrogen atom can influence peptide conformation and resistance to proteolytic degradation.
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].
As a valine analogue and amino acid derivative, N-Methyl-L-valine has been studied in the context of amino acid and amino acid derivative research. Amino acids and their derivatives have been commercially used as ergogenic supplements, affecting the release of anabolic hormones, the availability of fuel for activity, mental performance under stress, and the prevention of exercise-induced muscle damage. They are regarded as advantageous synergistic food ingredients. The N-methylation introduces specific structural constraints that can modulate peptide conformation and biological activity when incorporated into peptides.
ln Vivo
Specific in vivo activity data for N-Methyl-L-valine as a standalone compound are not documented in the literature. As an amino acid building block for peptide synthesis, its in vivo effects are determined by the final peptide construct into which it is incorporated. N-Methylation of amino acids in peptides is known to enhance proteolytic stability and modulate bioavailability, as the methyl group can protect the peptide bond from enzymatic cleavage. The compound's role in protein engineering allows researchers to investigate how methylation affects protein folding, function, or stability in vivo.
Enzyme Assay
In vitro enzyme/receptor binding assays for N-Methyl-L-valine typically involve its use as a building block in peptide synthesis rather than direct binding evaluation. When incorporated into peptides, the resulting N-methylated peptides can be assessed for target binding affinity using standard biochemical assays such as radioligand binding, fluorescence polarization, or surface plasmon resonance (SPR). The N-methyl group can significantly alter the binding affinity and selectivity of peptides by introducing steric constraints and modifying hydrogen bonding interactions. Typical assay conditions include buffered solutions at physiological pH.
Cell Assay
In vitro cell-based studies using N-Methyl-L-valine typically focus on the biological activities of peptides synthesized with this building block rather than the compound itself. When incorporated into peptides, the resulting N-methylated constructs can be evaluated in various cell-based assays including cell viability assays (e.g., MTT), receptor binding and internalization studies, and functional readouts such as calcium flux, reporter gene activation, or cytokine secretion. N-methylation can enhance peptide stability in cell culture by protecting against proteolytic degradation. Standard cell culture conditions (37°C, 5% CO₂) with appropriate cell lines are employed.
Animal Protocol
In vivo animal studies using N-Methyl-L-valine are conducted with peptides synthesized from this building block rather than the compound itself. Typical experimental designs involve administration of the N-methylated peptide construct to rodent models (e.g., mice or rats) via appropriate routes. The N-methyl group can enhance peptide stability and prolong circulation half-life by protecting against proteolytic degradation. Endpoints may include efficacy measurements (e.g., tumor growth inhibition, biomarker modulation), pharmacokinetic sampling, and toxicological assessments. All procedures must comply with institutional animal care and use guidelines.
ADME/Pharmacokinetics
Specific pharmacokinetic data for N-Methyl-L-valine as a standalone compound are not well characterized. The compound is highly water-soluble, with solubility in H₂O at 100 mg/mL (762.37 mM). It has a molecular weight of 131.17 g/mol and is typically stored as a powder at -20°C (stable for 3 years) or 4°C (stable for 2 years); in solvent, it can be stored at -80°C for 6 months or -20°C for 1 month. When incorporated into peptides, the pharmacokinetic properties are determined by the overall peptide construct. N-methylation can enhance peptide stability and prolong half-life by protecting against proteolytic degradation.
Toxicity/Toxicokinetics
Toxicological data for N-Methyl-L-valine as a standalone compound are not extensively documented. The compound is intended for research use only and is not approved for human or veterinary use. Standard safety precautions should be observed when handling this compound, including the use of appropriate personal protective equipment. As a naturally occurring amino acid derivative, its toxicity profile is expected to be relatively low, though comprehensive toxicological studies have not been published. For peptides synthesized using this building block, standard toxicological assessments would be performed on the final peptide product rather than on the individual amino acid building block.
