Caffeine

Caffeine is a methylxanthine alkaloid naturally found in various plant parts that acts as an antagonist at central adenosine receptors at relevant physiological concentrations (IC50 = ~30 µM). It alters fatigue, mood, alertness, motor reaction time, vascular hemodynamics, and pain sensation. Caffeine has also been implicated in carcinogenesis, although the concentrations used to affect cell cycling and apoptosis in the laboratory may not be commonly achieved in vivo.Formal Name: 3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione.
