Mode of Action of Desoxypyridoxine

Abstract
Using tyrosine decarboxylase it was demonstrated that desoxypyridoxine, an antimetabolite for the vit. B6 group, exerts its inhibitory effect by being first converted into desoxypyridoxine phosphate. This compound competes with pyridoxal phosphate for the apoenzyme but has little or no effect once the latter has combined with the apoenzyme.
