Product Description
Sodium 3-methyl-2-oxobutanoate is the precursor of pantothenic acid in Escherichia coli.
Sodium 3-methyl-2-oxobutanoate, also known as sodium α-ketoisovalerate or sodium dimethylpyruvate, is the sodium salt of α-ketoisovaleric acid, the keto-analogue of the essential amino acid L-valine. It has the molecular formula C5H7NaO3 and a molecular weight of 138.10. This compound is an alpha-keto ester derivative used in biochemical research and as a metabolic intermediate.
Biological Activity I Assay Protocols (From Reference)
Targets
Microbial Metabolite Human Endogenous Metabolite
The primary targets of sodium 3-methyl-2-oxobutanoate are enzymes involved in amino acid metabolism, particularly the branched-chain amino acid (BCAA) metabolism pathway. As the keto-analogue of valine, it is a substrate for branched-chain aminotransferase and is involved in the transamination and oxidation of branched-chain amino acids.
ln Vitro
In Escherichia coli, alpha-ketoisovaleric acid, or sodium 3-methyl-2-oxobutanoate, is a precursor to pantothenic acid[1]. Alpha-ketoisovaleric acid, also known as sodium 3-methyl-2-oxobutanoate, increases alpha-ketoisocaproic acid and alpha-keto-beta-methyl-n-valeric acid. However, it also depletes the corresponding amino acids and results in an early decrease in ornithine and a late increase in plasma arginine[2].
In vitro, sodium 3-methyl-2-oxobutanoate is used in studies of amino acid metabolism and as a substrate for enzyme assays. It serves as a precursor for the synthesis of valine via transamination reactions and is used to study the regulation of branched-chain amino acid catabolism. The compound is also used in cell culture media as a nutrient supplement.
ln Vivo
In rats, convulsions are induced by sodium 3-methyl-2-oxobutanoate (alpha-ketoisovaleric acid) via GABAergic and glutamatergic mechanisms[3].
In vivo, sodium 3-methyl-2-oxobutanoate is metabolized through the branched-chain amino acid pathway. It can be converted to valine via transamination or further oxidized to produce energy. As a keto-analogue of valine, it may be used in nutritional studies to assess amino acid metabolism and the effects of dietary interventions on BCAA homeostasis.
Enzyme Assay
In vitro enzyme assays for sodium 3-methyl-2-oxobutanoate typically measure the activity of branched-chain aminotransferase (BCAT) or branched-chain α-keto acid dehydrogenase (BCKDH). The compound is used as a substrate, and the formation of valine or the decarboxylation product is monitored spectrophotometrically or by chromatographic methods to assess enzyme activity.
Cell Assay
In vitro cell experiments with sodium 3-methyl-2-oxobutanoate involve treating cell lines with the compound to study branched-chain amino acid metabolism. Cells such as hepatocytes or muscle cells are cultured with the compound, and the levels of valine, other amino acids, and metabolic intermediates are measured. The effects on gene expression of metabolic enzymes and cell signaling pathways may also be assessed.
Animal Protocol
In vivo animal experiments with sodium 3-methyl-2-oxobutanoate involve administering the compound to animal models to study branched-chain amino acid metabolism. Blood, tissue, and urine samples are collected at various time points and analyzed for the levels of the compound, valine, and other metabolites. This approach is used to study the effects of dietary interventions, disease states, or genetic manipulations on BCAA metabolism.
ADME/Pharmacokinetics
Pharmacokinetic data for sodium 3-methyl-2-oxobutanoate are limited. As a small, water-soluble alpha-keto acid salt, it is expected to be readily absorbed and distributed in the body. It is metabolized through the branched-chain amino acid pathway and excreted as metabolites. The compound is stable and commonly used as a research reagent.
Toxicity/Toxicokinetics
Toxicological data for sodium 3-methyl-2-oxobutanoate are limited. As a naturally occurring metabolite and a salt of an alpha-keto acid, it is generally considered to have low toxicity. The compound is intended for research use only and not for human consumption. No comprehensive toxicological studies have been reported.
