Description

Pyridoxine is the 4-methanol form of vitamin B6 and is converted to pyridoxal 5-phosphate in the body. Pyridoxal 5-phosphate is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and vitamin B6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading. Pyridoxine is one of the compounds that can be called vitamin B6. Pyridoxine assists in the balancing of sodium and potassium as well as promoting red blood cell production. It is linked to cancer immunity and helps fight the formation of homocysteine. It has been suggested that Pyridoxine might help children with learning difficulties, and may also prevent dandruff, eczema, and psoriasis. In addition, pyridoxine can help balance hormonal changes in women and aid in immune system. Lack of pyridoxine may cause anemia, nerve damage, seizures, skin problems, and sores in the mouth. Deficiency, though rare because of widespread distribution in foods, leads to the development of peripheral neuritis in adults and affects the central nervous system in children.

Toxicity Profile

Route of Exposure

Oral; parenteral (intramuscular). The B vitamins are readily absorbed from the gastrointestinal tract, except in malabsorption syndromes. Pyridoxine is absorbed mainly in the jejunum.

Mechanism of Toxicity

Vitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate (PLP) and pyridoxamine 5'-phosphate (PMP). Although all six of these compounds should technically be referred to as vitamin B6, the term vitamin B6 is commonly used interchangeably with just one of them, pyridoxine. Vitamin B6, principally in its biologically active coenzyme form pyridoxal 5'-phosphate, is involved in a wide range of biochemical reactions, including the metabolism of amino acids and glycogen, the synthesis of nucleic acids, hemogloblin, sphingomyelin and other sphingolipids, and the synthesis of the neurotransmitters serotonin, dopamine, norepinephrine and gamma-aminobutyric acid (GABA).

Metabolism

Hepatic. Half Life: 15-20 days

Toxicity Values

LD50: 4 gm/kg (oral, rat)

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

No indication of carcinogenicity to humans (not listed by IARC).

Uses/Sources

For the treatment of vitamin B6 deficiency and for the prophylaxis of isoniazid-induced peripheral neuropathy.

Targets

Target Details

1. Alpha-aminoadipic semialdehyde dehydrogenase

General Function:: L-aminoadipate-semialdehyde dehydrogenase activity
Specific Function:: Multifunctional enzyme mediating important protective effects. Metabolizes betaine aldehyde to betaine, an important cellular osmolyte and methyl donor. Protects cells from oxidative stress by metabolizing a number of lipid peroxidation-derived aldehydes. Involved in lysine catabolism.
Gene Name:: ALDH7A1
Uniprot ID:: P49419
Molecular Weight:: 58486.74 Da

Target Details

2. Cystathionine beta-synthase

General Function:: Ubiquitin protein ligase binding
Specific Function:: Hydro-lyase catalyzing the first step of the transsulfuration pathway, where the hydroxyl group of L-serine is displaced by L-homocysteine in a beta-replacement reaction to form L-cystathionine, the precursor of L-cysteine. This catabolic route allows the elimination of L-methionine and the toxic metabolite L-homocysteine (PubMed:23981774, PubMed:20506325, PubMed:23974653). Also involved in the production of hydrogen sulfide, a gasotransmitter with signaling and cytoprotective effects on neurons (By similarity).
Gene Name:: CBS
Uniprot ID:: P35520
Molecular Weight:: 60586.05 Da

Target Details

3. Phosphoserine aminotransferase

General Function:: O-phospho-l-serine:2-oxoglutarate aminotransferase activity
Specific Function:: Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4-phosphonooxybutanoate to phosphohydroxythreonine.
Gene Name:: PSAT1
Uniprot ID:: Q9Y617
Molecular Weight:: 40422.355 Da

Target Details

4. Pyridoxal kinase

General Function:: Zinc ion binding
Specific Function:: Required for synthesis of pyridoxal-5-phosphate from vitamin B6.
Gene Name:: PDXK
Uniprot ID:: O00764
Molecular Weight:: 35102.105 Da

Target Details

5. Pyridoxal phosphate phosphatase

General Function:: Pyridoxal phosphatase activity
Specific Function:: Protein serine phosphatase that dephosphorylates 'Ser-3' in cofilin and probably also dephosphorylates phospho-serine residues in DSTN. Regulates cofilin-dependent actin cytoskeleton reorganization. Required for normal progress through mitosis and normal cytokinesis. Does not dephosphorylate phospho-threonines in LIMK1. Does not dephosphorylate peptides containing phospho-tyrosine. Pyridoxal phosphate phosphatase. Has some activity towards pyridoxal 5'-phosphate (PLP), pyridoxine 5'-phosphate (PMP) and pyridoxine 5'-phosphate (PNP), with a highest activity with PLP followed by PNP.
Gene Name:: PDXP
Uniprot ID:: Q96GD0
Molecular Weight:: 31697.735 Da

Target Details

6. Serum albumin

General Function:: Toxic substance binding
Specific Function:: Serum albumin, the main protein of plasma, has a good binding capacity for water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc.
Gene Name:: ALB
Uniprot ID:: P02768
Molecular Weight:: 69365.94 Da
