Product Description
N-Methyl-DL-valine (N-Methylvaline) HCl is a valine analogue that is metabolized in buds to cysteine, alanine, tyrosine, tryptophan, citric acid, and succinic acid. N-Methyl-DL-valine participates in the modification of the anti-tubulin agent monomethyl auristatin F (MMAF), making it hydrophobically functional and increasing cell permeability.
N‑Methyl‑DL‑valine hydrochloride is a valine derivative, a racemic mixture of the N‑methylated form of the amino acid valine. It has a molecular formula of C6H14ClNO2 and a molecular weight of 167.63. This compound is metabolized to cysteine, alanine, tyrosine, tryptophan, citric acid, and succinic acid in the sprout. N‑Methyl‑DL‑valine hydrochloride is involved in the modification of monomethyl auristatin F (MMAF), an anti‑tubulin agent, making it hydrophobic functionalization and increasing cell permeability.
Biological Activity I Assay Protocols (From Reference)
Targets
N‑Methyl‑DL‑valine hydrochloride does not have a specific biological receptor target. It is a valine analogue that serves as a chiral building block in asymmetric synthesis and peptide synthesis. Its N‑methylation modifies the properties of peptides, potentially affecting their hydrophobicity, stability, and cell permeability. The compound is involved in the modification of MMAF, increasing cell permeability.
ln Vitro
In vitro, N‑Methyl‑DL‑valine hydrochloride is metabolized to cysteine, alanine, tyrosine, tryptophan, citric acid, and succinic acid in the sprout. It serves as a building block in peptide synthesis, where its N‑methylation can modify the properties of the resulting peptides. The compound is involved in the hydrophobic functionalization of MMAF, increasing cell permeability.
ln Vivo
Specific in vivo activity data for N‑Methyl‑DL‑valine hydrochloride are not extensively detailed in available sources. As a valine derivative, it may be incorporated into metabolic pathways, but its primary use is as a research chemical and building block rather than as a pharmacologically active compound.
Enzyme Assay
Non‑cellular assays for N‑Methyl‑DL‑valine hydrochloride are not typically performed as it is a building block rather than a bioactive compound. Its identity and purity can be confirmed by analytical techniques such as HPLC, NMR, and mass spectrometry. Its role in peptide synthesis can be assessed by monitoring peptide coupling reactions.
Cell Assay
In vitro cellular assays for N‑Methyl‑DL‑valine hydrochloride are not typically performed as it is primarily used as a chemical building block. When incorporated into peptides or drug conjugates, its effects on cell permeability and activity can be assessed in cell‑based assays.
Animal Protocol

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
