Part Descriptions
LP15953-0 Xanthine
A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed)

LP15953-0 Xanthine
Xanthine is a product on the pathway of purine degradation and is converted to uric acid by the action of the xanthine oxidase (xanthine dehydrogenase) enzyme. Some people lack sufficient xanthine oxidase, and thus xanthine cannot be converted to uric acid. This rare genetic disorder is called xanthinuria results from excessive excretion of xanthine into the urine. This disorder can result in urolithiasis and sometimes myopathy from xanthine deposition. Elevated xanthine can also result from allopurinol treatment. Xanthine is also the core chemical component of a group of alkaloids that are commonly used for their effects as mild stimulants and as bronchodilators, notably in treating the symptoms of asthma. Their effects, however, are widespread and their therapeutic range is narrow and so they are not the drug of choice in asthma treatment. Methylated xanthine derivatives include caffeine, theophylline, and theobromine (found mainly in chocolate). These drugs inhibit phosphodiesterase and antagonise adenoine.
