pyridoxal

Pyridoxal represents an active form of vitamin B6 [1].

Pyridoxal phosphate (Vitamin B6 phosphate) is the active form of vitamin B6 and a coenzyme for many pyridoxal phosphate (PLP)-dependent enzymes. PLP is involved in numerous enzymatic transamination, decarboxylation and deamination reactions; it is necessary for the synthesis of amino acids and amino acid metabolites, and for the synthesis and or catabolism of certain neurotransmitters, including the conversion of glutamate into gamma-aminobutyric acid (GABA) and levodopa into dopamine. PLP can be used as a dietary supplement in cases of vitamin B6 deficiency. Reduced levels of PLP in the brain can cause neurological dysfunction.

pyridoxal isonicotinoyl hydrazone (PIH) is a cell-permeable and relatively non-toxic iron (Fe3+) chelator that shows high iron chelation efficacy both in vitro and in vivo.

Pyridoxal-d3 is a deuterated compound of Pyridoxal.

Pyridoxal-d3 Hydrochloride is a deuterated compound of Pyridoxal Hydrochloride.

Pyridoxal phosphate (PLP, pyridoxal 5'-phosphate, P5P), known as an active form of vitamin B6, is a coenzyme involved in many enzymatic reactions.

Pyridoxine (Vitamin B6) is the 4-methanol form of vitamin B6 and is converted to pyridoxal 5-phosphate in the body. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading.

L-Cycloserine ((-)-Cycloserine) irreversibly inhibits GABA pyridoxal 5′-phosphate-dependent aminotransferase in E. coli, as well in the brains of various animals, results in increased levels of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter in vivo.

Pyridoxine hydrochloride (Vitamin B6) is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

2-Ketoglutaric acid Sodium (AKG) is a key molecule in the TCA cycle. It can be produced from glutamate by oxidative deamination via glutamate dehydrogenase and as a product of pyridoxal phosphate-dependent transamination reactions (mediated by branched-chain amino acid transaminases) in which glutamate is a common amino donor.

U-7524, also known as AOAA and Aminooxyacetic acid, is an inhibitor of 4-aminobutyrate aminotransferase (GABA-T). AOAA is also a general inhibitor of pyridoxal phosphate (PLP)-dependent enzymes (this includes GABA-T). It functions as an inhibitor by attac

Pyridoxine-d2 HCl is a deuterated compound of Pyridoxine HCl. Pyridoxine HCl has a CAS number of 58-56-0. Pyridoxine hydrochloride is the 4-methanol form of vitaminB6 which is converted to pyridoxal phosphate which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid.

Alanine aminotransferase (ALT), a pyridoxal-dependent enzyme, catalyzes the reversible interconversion of L-alanine and 2-oxoglutarate into pyruvate and L-glutamate [1].

Pyridoxamine 5′-phosphate, the active form of vitamin B6 phosphorylated, acts as a central metabolite, potent antioxidant, and enzyme substrate by serving as the aminated counterpart to pyridoxal 5'-phosphate hydrate. It plays a pivotal role as a cofactor for various enzymes and is a prominent vitamin B6 vitamer. The compound can be interconverted with pyridoxal 5'-phosphate hydrate [1].

Cap-dependent endonuclease-IN-25 is a macrocyclic pyridoxal derivative and a potent inhibitor of cap-dependent nucleic acid endonucleases (CEN) with potential for studying viral infections caused by viruses of the Orthomyxoviridae family.

Tyrosine decarboxylase (TDC; TyrDC), a pyridoxal 5'-phosphate (PLP)-dependent enzyme, catalyzes the decarboxylation of tyrosine, leading to the production of tyramine and carbon dioxide. This enzyme is prevalent in plants, insects, and various microorganisms, playing a significant role in biochemical research.

4-Deoxypyridoxine (4-DPD) is a vitamin B6 antimetabolite with diverse biological activities. It inhibits transport of pyridoxine , pyridoxal, and pyridoxamine in and reduces growth of S. carlsbergensis cells. 4-DPD inhibits sphingosine-1-phosphate (S1P) lyase and reduces cyclic stretch-induced apoptosis in alveolar epithelial MLE-12 cells. 4-DPD (5 mg, i.p.) reduces lysyl oxidase activity by 26% and reduces collagen and elastin crosslinking, resulting in limb abnormalities in chick embryos. It decreases latency to first seizure in mice (ED50 = 1 mmol kg) and increases the occurrence and duration of myoclonic responses in baboons with photosensitive epilepsy. 4-DPD reduces TNF-α and IL-6 production in mice infected with T. spiralis.

L-Methionine γ-lyase (Methionine lyase), a multifaceted enzyme in the γ-family of pyridoxal-5’-phosphate (PLP)-dependent enzymes, catalyzes the α, γ-elimination of L-methionine and homocysteine. This enzyme exhibits anticancer and anti-infectious properties and is utilized in homocysteinemia research [1][2][3].
