The effects of 8-phenyl and 8-cycloalkyl substituents on the activity of theophylline, caffeine, 1,3-dipropylxanthine, 1,3-dipropyl-7-methylxanthine, 3-propylxanthine, and 1-propylxanthine at A1 adenosine receptors of rat brain and fat cells and at A2 adenosine receptors of rat pheochromocytoma PC12 cells and human

Human rTNF-alpha (greater than or equal to U/ml) decreased PMN nondirected and directed migration to FMLP to approximately 50% of control. Adenosine (100 microM) almost completely restored hrTNF-inhibited migration (nondirected from 54 to 92% and directed migration to from 54

Much evidence has accumulated supporting the hypothesis that the purine nucleoside adenosine may indeed function as a neuromodulator in the mammalian retina, but to date no reports have directly illustrated a physiological role for this nucleoside. In other regions of
The reactivity of retinal arterioles and venules to exogenous and endogenous adenosine was investigated in the newborn piglet eye in vivo. The retinal microcirculation of isoflurane-anesthetized newborn pigs was observed at 310x using videomicroscopy, and changes in the diameter of

Caffeine, a nonselective adenosine receptor antagonist, 7-methyl-1,3-dipropylxanthine, a purported A2 selective antagonist and a 1,3-dipropyl-8-phenylxanthine amine congener (XAC), an A1 selective antagonist, were evaluated for their in vivo selectivity at A1 vs. A2 adenosine receptors. Blockade of the negative chronotropic
