pyruvate

Sodium dichloroacetate (BCA) , a specific inhibitor of pyruvate dehydrogenase kinase (PDK) with IC50 values of 183 and 80 μM for PDK2 and PDK4 respectively, has been shown to derepress a mitochondrial potassium-ion channel axis, trigger apoptosis in cancer cells, and inhibit tumor growth.

Ethyl pyruvate is a simple aliphatic ester of pyruvic acid and has been shown to have robust neuroprotective effects via its anti-inflammatory, anti-oxidative, and anti-apoptotic functions.

Pyruvate oxidase (PoxB) is a thiamine pyrophosphate-dependent oxidase, a key enzyme in glucose metabolism, and is used in the study of invasive pneumococcal disease.

Sodium phenylpyruvate (Phenylpyruvic acid, sodium salt) is a substrate for phenylpyruvate decarboxylase and phenylpyruvate tautomerase.

DL-Serine is a non-essential amino acid and a natural ligand and allosteric activator of pyruvate kinase M2.

Potassium 1-carboxyvinyl hydrogenphosphate (PEP-K) is involved in glycolysis and gluconeogeneis. In glycolysis, PEP is metabolized by Pyruvate Kinase to yield pyruvate. In plants, PEP is involved in the formation of aromatic amino acids as well as in the carbon fixation pathway.

Alanine is a nonessential amino acid made in the body from the conversion of the carbohydrate pyruvate or the breakdown of DNA and the dipeptides carnosine and anserine. D-Alanine ((R)-Alanine) is a weak GlyR (inhibitory glycine receptor) and PMBA agonist, with an EC50 of 9 mM for GlyR.

Acetyl phosphate lithium potassium (Lithium potassium acetyl phosphate) is a compound involved in taurine and hypotaurine metabolism as well as pyruvate metabolism. Acetyl phosphate lithium potassiu is generated from sulfoacetaldehyde, converted to acetyl-CoA and acetate via phosphate acetyltransferase and acetate kinase respectively. Acetyl phosphate lithium potassiu is also an intermediate in pyruvate metabolism.

(S)-Malic acid ((S)-2-Hydroxysuccinic acid) is a tart-tasting organic dicarboxylic acid found in many sour foods, such as apples, and contributes to the sourness of green apples and tartness of wine, although its concentration decreases with fruit ripeness (wikipedia). In its ionized form, it is called malate, an intermediate in the TCA cycle alongside fumarate, and can be formed from pyruvate through anaplerotic reactions. In humans, malic acid is derived from food sources and synthesized in the body via the citric acid cycle in mitochondria, playing a crucial role in energy production under both aerobic and anaerobic conditions. Under aerobic conditions, malate is oxidized to oxaloacetate, providing reducing equivalents via the malate-aspartate redox shuttle, while during anaerobic conditions, its simultaneous reduction to succinate and oxidation to oxaloacetate removes excess reducing equivalents, reversing hypoxia's inhibition of glycolysis and energy production. Studies on rats have shown that tissue malate depletes following exhaustive physical activity, suggesting that malic acid deficiency may cause physical exhaustion. Administering malic acid to rats has been shown to elevate mitochondrial malate, increasing mitochondrial respiration and energy production.

Shikonin (Anchusa acid) is a natural product, a TMEM16A chloride channel inhibitor (IC50=6.5 μM) and selective PKM2 inhibitor. Shikonin exhibits antitumor, anti-inflammatory and wound healing activities.

L-2-Phosphoglyceric acid disodium salt is a glyceric acid which serves as the substrate in glycolysis. It is catalyzed by enolase into phosphoenolpyruvate.

Sarmentosin significantly lowers the SGPT level of patients suffering from chronic viral hepatitis, and shows a suppressive effect on cell-mediated immune responses in mice. It shows a good effect in lowering serum glutamate-pyruvate transaminase.

Fulvotomentoside B, a saponin derived from Lactobacillus flavus, displays hepatoprotective properties. It notably decreases serum glutamate pyruvate transaminase (SGPT) and triacylglycerol (GT) concentrations in mice subjected to hepatic injury induced by CCl₄, d-galactosamine (d-gal), and acetaminophen, while also significantly mitigating liver tissue damage [1].

Hydroxypyruvic acid is an intermediate in the metabolism of glycine, serine, and threonine. It is a substrate for serine-pyruvate aminotransferase and glyoxylate reductase hydroxypyruvate reductase.

Alkannin is a potent and specific inhibitor of tumor-specific pyruvate kinase-M2 (PKM2) without affecting PKM1 or pyruvate kinase-L (PKL), making it a potential anticancer agent [1].

SAICAR, an intermediate of de novo purine nucleotide biosynthesis, selectively activates pyruvate kinase isoform M2 (PKM2) with an EC50 of 0.3 mM.

Dicoumarol (Dicumarol) is a hydroxycoumarin originally isolated from molding sweet-clover hay, with anticoagulant and vitamin K depletion activities. Dicoumarol is a competitive inhibitor of vitamin K epoxidereductase; thus, it inhibits vitamin K recycling and causes depletion of active vitamin K in blood. This prevents the formation of the active form of prothrombin and several other coagulant enzymes, and inhibits blood clotting.

L-2-Phosphoglyceric acid (L-2-Phosphoglyceric acid disodium salt) is a glyceric acid which serves as the substrate in the ninth step of glycolysis. It is catalyzed by enolase into phosphoenolpyruvate (PEP), the penultimate step in the conversion of glucose to pyruvate.
