Inhibition of inositol trisphosphate-induced calcium release by caffeine is prevented by ATP.
Biochem. J. 300 , 81-84, (1994) We have investigated the effect of various methylxanthines on the basal and InsP3-stimulated unidirectional 45Ca2+ efflux from permeabilized A7r5 cells under different experimental conditions. We report that caffeine and theophylline inhibit the InsP3-induced... |

Determination of caffeine and its metabolites in urine by high-performance liquid chromatography and capillary electrophoresis.
Scand. J. Clin. Lab. Invest. 54 , 305-315, (1994) Caffeine (CA) and its 14 main metabolites were determined in urine by reversed-phase high-performance liquid chromatography (RP-HPLC) and capillary electrophoresis (CE). After addition of 1,3,9-trimethylxanthine, uracil and beta-hydroxyethyltheophylline as in... |

Computational study of the binding modes of caffeine to the adenosine A2A receptor.
J. Phys. Chem. B 115(47) , 13880-90, (2011) Using the recently solved crystal structure of the human adenosine A(2A) receptor, we applied MM/PBSA to compare the binding modes of caffeine with those of the high-affinity selective antagonist ZM241385. MD simulations were performed in the environment of t... |
