Effect of adenosine deaminase on cardiac interstitial adenosine
American Journal of Physiology-Heart and Circulatory Physiology, 1992Adenosine deaminase was infused into isolated perfused guinea pig hearts to determine its effect on myocardial adenosine levels. The enzyme was administered during constant coronary flow perfusion at 6.11 +/- 0.36 ml.min-1.g-1. Venous adenosine was measured in samples of pulmonary artery effluent; epicardial and endocardial adenosine were measured ...

Adenosine Metabolism, Adenosine Kinase, and Evolution
2012The enzyme adenosine kinase (AdK, ADK, or AK) plays an important role in regulating the intracellular as well as extracellular concentrations of adenosine and hence its diverse physiological actions. In view of the enormous pharmacological potential of adenosine, there has been much interest in studying adenosine kinase over the past few decades.

Adenosine, Adenosine Receptors and the Actions of Caffeine *
Pharmacology & Toxicology, 1995Abstract:Of the known biochemical actions of caffeine, only inhibition of adenosine receptors occurs at concentrations achieved during normal human consumption of the drug. Under normal physiological conditions, adenosine is present in sufficient concentrations to activate A1and A2areceptors.
