Inhibition of xanthine oxidase and related enzymes by 6-pteridyl aldehyde.
We have recently reported’ the inhibition of xanthopterin oxidase and xanthine oxidase by synthetic pteroylglutamic acid (PGA). However, since an exceptionally pure sample2 of PGA, which was later examined, possessed less than one-sixth of the inhibitory power previously observed, it appears possible that the effect is due to traces of a contaminant. The observation by Lowry and Bessey3 that 2-...
متن کاملIn vitro study of 6-mercaptopurine oxidation catalysed by aldehyde oxidase and xanthine oxidase.
In spite of over 40 years of clinical use of 6-mercaptopurine, many aspects of complex pharmacology and metabolism of this drug remain unclear. It is thought that 6-mercaptopurine is oxidized to 6-thiouric acid through 6-thioxanthine or 8-oxo-6-mercaptopurine by one of two molybdenum hydroxylases, xanthine oxidase (XO), however, the role of other molybdenum hydroxylase, aldehyde oxidase (AO), i...
متن کاملThe inhibition of xanthine oxidase by flavonoids and related compounds.
Investigations of the inhibition of the activity of xanthine oxidase in vitro have yielded a number of substances which have been reported to exert marked inhibitory actions at low concentrations. Among these are p-aminophenol in its oxidized form (l), pyrogallol (a), bromoacetophenone (3)) 6-pteridylaldehyde (4)) and 6-hydroxymethylpterin (5). An examination of the structures of these compound...
متن کاملRole of Aldehyde Oxidase and Xanthine Oxidase in the Metabolism of Purine-Related Drugs
Purines are natural compounds that are found in all of the body's cells. They are the most widely distributed kind of N-heterocyclic substances in nature. Purines provide part of the chemical structure of some important co-enzymes and the genes of plants and animals. These compounds also participate in membrane signal transduction, translation and protein synthesis and in the form of purine nuc...
