Pyrithioxin (Encefabol) is a neurodynamic compound, combined with a short period of hyperventilation (HV) was applied in cerebral infarct patients with Hemiplegia. Pyrithioxin is regarded as an encephalotropic or nootropic compound and is reported to act mainly by producing decisive improvements in cerebral metabolism.

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.

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.

Quinaldic acid is an endogenous metabolite.Quinaldic acid is a metal chelator.

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.

Pyrithioxin dihydrochloride (Pyrithioxine HCl) has anti-nociceptive and anti-allodynic effects, can promote the metabolism of glucose and amino acids in the brain, improve systemic assimilation, and can be used to study neurological diseases such as atherosclerosis. Pyrithioxin dihydrochloride can induce severe cholestatic hepatitis.

3-Hydroxypyridine exhibits inhibitory activity against DNA topoisomerase 2-beta (Topo IIβ) and HIV-1 replication in Sup-T1 cells, making it useful for studying the HIV-1 virus.

Pyridoxylamine dihydrochloride (Pyridorin) is a hydrochloride salt of one form of vitamin B6.

Pyridoxal 5'-phosphate hydrate (PLP)(1:x), the active form of vitamin B6, is a cofactor for many different enzymes involved in transamination reactions, including mitochondrial cysteine desulfurase, cystathionine γ-synthase, various aminotransferases, and a d-serine dehydratase.

4,4'-Disulfanediylbis(2-aminobutanoic acid) (DL-Homocystine) is the double-bonded form of homocysteine that occurs transiently before being converted to harmless cystathionine via a vitamin B6-dependent enzyme. Homocystine and homocysteine-cysteine mixed disulfide account for over 98% of total homocysteine in plasma from healthy individuals.

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.

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

A6770 is an inhibitor of sphingosine-1-phosphate (S1P) lyase.1It induces accumulation of [3H]sphinganine-1-phosphate ([3H]dhS1P), an S1P lyase substrate, in IT-79MTNC3 cells that endogenously express high levels of S1P lyase (EC50= <0.01 μM), an effect that is reduced in the presence of vitamin B6(EC50= <100 μM). 1.Ohtoyo, M., Tamura, M., Machinaga, N., et al.Scintillation proximity assay to detect the changes in cellular dihydrosphingosine 1-phosphate levelsLipids51(10)1207-1216(2016)

Methylmalonyl coenzyme A (methylmalonyl-CoA) is an intermediate in multiple metabolic pathways in bacteria and eukaryotes.1,2,3It is an intermediate in carbon assimilation in certain bacteria and carbon fixation in plants.1,2Methylmalonyl-CoA is converted to succinyl-CoA by methylmalonyl-CoA mutase with vitamin B12as a coenzyme.3A deficiency in vitamin B12leads to a build-up of methylmalonyl-CoA.4 1.Anthony, C.How half a century of research was required to understand bacterial growth on C1 and C2 compounds; the story of the serine cycle and the ethylmalonyl-CoA pathwaySci.
