The first naturally occurring form of vitamin B6 was isolated in 1938. It has the structure, confirmed by chemical synthesis (1939), of 3-hydroxy-4,5-bis(hydroxymethyl)-2-methylpyridine (I; R = -CHzOH). The trivial name “pyridoxine,” proposed for this compound by P. GyGrgy, came into general use as a synonym for “vitamin Be.” Two other natural compounds possessing vitamin B6 activity, detected ...

Pyridoxine dependent epilepsy (PDE) is caused by likely pathogenic variants in ALDH7A1 (PDE-ALDH7A1) and inherited autosomal recessively. Neurotoxic alpha-amino adipic semialdehyde (alpha-AASA), piperideine 6-carboxylate and pipecolic acid accumulate in body fluids. Neonatal or infantile onset seizures refractory to anti-epileptic medications are clinical features. Treatment with pyridoxine, ar...

Attempts have been made to clarify the effect of pyridoxine deficiency as well as its overdosis on growth of transplantable tumors in mouse and rat. The growth of transplantable solid tumor in pyridoxine deficient animals was remarkably suppressed while that of ascites tumor was not. The tumor bearing host was administered with a large amounts of pyridoxine and pyridoxal phosphate resulting in ...

Borax is one of the compounds boron (B), which widely used as an anti-fungal, wood preservative, and antiseptic in cosmetics. Boron can form complexes with biomolecules such pyridoxine, so it interesting to know interaction between borax pyridoxine. This study seeks investigate complexation boron, obtained from borax, pyridoxine under various conditions time, temperature, amount The resulting c...

MICROCYTIC hypochromic anemia induced by a diet deficient in pyridoxine is well documented in swine,’ monkeys,2 dogs,3 cats,4 ducks,5 and chicks.#{176}In man, pyridoxine deficiency anemia was first described in 1956 by Harris et al.;7 subsequently an increasing number of cases have been reported by others. In 1953, Synderman et al.8 produced pyridoxine deficiency in two infants with cerebral de...

The natural vitamin, pyridoxine, in the millimolar range is toxic to cultured rat hepatoma cells. A pyridoxine-resistant Fu5-5 rat hepatoma cell line was established by a stepwise increase in the concentration of pyridoxine in the medium. The newly established cell line, referred to as clone 10 (Cl.10), is resistant to killing by pyridoxine in concentrations up to 5 mM. Saturation kinetics for ...
