• Verwenden

  Pyridoxine is one of the vitamins of the B6 complex; present in many foodstuffs (yeast, liver and cereals). Pyridoxine has a role in transporting protein Bsu1, Pyridoxine contributes to thiamine uptak e; characterization of thiamine (vitamin B1) transporter Thi9 from Schizosaccharomyces pombe.

• Application

  Pyridoxine hydrochloride has been used:
  As a vitamin component in a chemically defined diet with balanced metal content for metal depletion studies;
  As a component of chemically defined medium (CDM) to culture Staphylococcus aureus WSPPA;
  As analytical reference standards for the determination of analytes in pharmaceutical preparations by chromatography and spectrophotometric techniques;
  As a vitamin to study the impact of protein expression and post-translational modifications specifically charge heterogeneity;
  As a medicine, it is used to prevent or treat certain neurological disorders (peripheral neuropathy) caused by certain drugs (e.g. isoniazid). It is also used in the treatment of certain hereditary disorders (e.g. flavoururic aciduria, hyperoxaluria, homocystinuria).

• Sicherheitsprofil

  Poison by intravenous route. Moderately toxic by ingestion, intramuscular, and subcutaneous routes. Human reproductive effects by ingestion and intramuscular routes: postpartum changes. Experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and HCl.

• Stoffwechsel

  Pyridoxine is metabolised to its active form pyridoxamine phosphate. It is stored mainly in the liver where there is oxidation to 4-pyridoxic acid and other inactive metabolites which are excreted in the urine.

• läuterung methode

  Purify the vitamin by recrystallisation from EtOH/Me2CO, n-BuOH or MeOH/Et2O. Its solubility in H2O is 22%, and in EtOH it is 1.1%. It is insoluble in Et2O and CHCl3. Acidic aqueous solutions are stable at 120o/30minute. The free base has m 159-160o after recrystallisation from Me2CO and sublimation at 140-145o/0.0001mm. It has UV max at 290nm ( 84,000), 253 and 325nm ( 3,700 and 7,100) in 0.1N aqueous HCl. [Khua & Wendt Chem Ber 71 780 1938, 72 311 1939, Harris & Folkers J Am Chem Soc 61 1242 1939, Harris et al.
