Description
Adenosine is a purine nucleoside comprising a molecule of adenine attached to a ribose sugar molecule moiety via a β-N9-glycosidic bond. It plays an important role in energy transfer. It is an endogenous purine nucleoside that modulates physiological process wherein cellular signaling by adenosine occurs through four known adenosine receptor subtypes (A1, A2A, A2B, and A3) Adenosine is an anti-inflammatory agent at the A(2A) receptor. Cardioprotective effects may relate to activation of A1 adenosine receptors.
