Adenosine A1 receptors in the brain are believed to play an important role in brain functioning. We have discovered a novel adenosine A1 receptor antagonist, FR194921 (2-(1-methyl-4-piperidinyl)-6-(2-phenylpyrazolo[1,5-a]pyridin-3-yl)-3(2H)-pyridazinone),

A depletable pool of adenosine in area CA1 of the rat hippocampus [PDF]
Adenosine plays a major modulatory and neuroprotective role in the mammalian CNS. During cerebral metabolic stress, such as hypoxia or ischemia, the increase in extracellular adenosine inhibits excitatory synaptic transmission onto vulnerable neurons via

Stimulation of endothelial adenosine Al receptors enhances adhesion of neutrophils in the intact guinea pig coronary system [PDF]
Objective: The primary aim was to determine the action of pathophysiologically relevant adenosine concentrations (0.1-1 μM) on adhesion of neutrophils to coronary endothelium.

Transient and selective blockade of adenosine A1-receptors by 8-cyclopentyl-1,3-dipropylxanthine (DPCPX) causes sustained epileptiform activity in hippocampal CA3 neurons of guinea pigs [PDF]
The effects of endogenously released adenosine on the excitability of hippocampal neurons were studied using the novel and highly selective adenosine A1-receptor antagonist 8-cyclopentyl-1,3-dipropylxanthine (DPCPX).

Degranulation of rat omental mast cells by A1 receptor agonists in vitro
The haemodynamic effects of adenosine are thought to result in part from a release of mast cell amines via A3 receptor stimulation. To investigate the nature of the receptors involved in adenosine-induced mast cell degranulation in the rat isolated ...

Laser irradiation activates spinal adenosine A1 receptor to alleviate osteoarthritis pain in monosodium iodoacetate injected rats [PDF]
The analgesic role of the adenosine A1 receptor is thought to involve the modulation of the spinal N-methyl D-aspartate receptor-mediated nociceptive pathway, which is suggested to be an underlying mechanism in chronic pain.

Allosteric interactions at adenosine A1 and A3 receptors: new insights into the role of small molecules and receptor dimerization [PDF]
Keywords:adenosine;allosterism;receptor;GPCR;dimerization;biased signalling The purine nucleoside adenosine is present in all cells in tightly regulated concentrations. It is released under a variety of physiological and pathophysiological conditions to

The Pl(A2) polymorphism of integrin beta(3) enhances outside-in signaling and adhesive functions. [PDF]
Genetic factors are believed to influence the development of arterial thromboses. Because integrin alpha(IIb)beta(3) plays a crucial role in thrombus formation, we analyzed receptor adhesive properties using Chinese hamster ovary and human kidney ...
