Sigma Aldrich Fine Chemicals Biosciences Caffeine powder ReagentPlu500G
Caffeine is a widely ingested pharmacologically active substance. It belongs to the class of methylxanthines. It is a naturally occurring alkaloid found in coffee cocoa and other plants. Caffeine might be associated with osteoporosis cardiovascular risk arrhythmia and gastrointestinal disturbances. Caffeine is used to treat orthostatic hypotension bronchopulmonary dysplasia and apnea of prematurity (AOP).
Sigma Aldrich Fine Chemicals Biosciences Xanthine 9910G
Xanthine is synthesized from guanine in the presence of guanine deaminase. Xanthine oxidase catalyzes the production of xanthine from hypoxanthine and its subsequent breakdown to uric acid. Xanthine derivatives are present in coffee tea and cocoa seeds. Xanthine has been proposed as a lead for the generation of pharmacologically active compounds.
