NCIt definition : A methylxanthine alkaloid found in the seeds, nuts, or leaves of a number of plants
native to South America and East Asia that is structurally related to adenosine and
acts primarily as an adenosine receptor antagonist with psychotropic and anti-inflammatory
activities. Upon ingestion, caffeine binds to adenosine receptors in the central nervous
system (CNS), which inhibits adenosine binding. This inhibits the adenosine-mediated
downregulation of CNS activity; thus, stimulating the activity of the medullary, vagal,
vasomotor, and respiratory centers in the brain. This agent also promotes neurotransmitter
release that further stimulates the CNS. The anti-inflammatory effects of caffeine
are due the nonselective competitive inhibition of phosphodiesterases (PDEs). Inhibition
of PDEs raises the intracellular concentration of cyclic AMP (cAMP), activates protein
kinase A, and inhibits leukotriene synthesis, which leads to reduced inflammation
and innate immunity.;
Alternative definition : CRCH: An alkaloid stimulant having a purine double-ring structure composed of eight
carbons and four nitrogen atoms with methyl groups attached to the nitrogen atoms
at the 1, 3, and 7 positions and having double bonds at the carbons in positions 2
and 6.; NCI-GLOSS: A substance found in the leaves and beans of the coffee tree, in tea, yerba
mate, guarana berries, and in small amounts in cocoa. It can also be made in the laboratory,
and is added to some soft drinks, foods, and medicines. Caffeine increases brain activity,
alertness, attention, and energy. It may also increase blood pressure, heart rate,
breathing rate, and the loss of water from the body in urine.;
