Cardioprotective actions of adenosine and adenosine analogs
1996Adenosine contributes to the physiological regulation of cardiovascular function and it clearly plays important roles under pathophysiological conditions. The nucleoside functions intracellularly as a major contributor to the general cellular economy and extracellularly as an important signalling molecule.

Sleep Medicine Reviews, 2002
Adenosine is directly linked to the energy metabolism of cells. In the central nervous system an increase in neuronal activity enhances energy consumption as well as extracellular adenosine concentrations. In most brain areas high extracellular adenosine concentrations, through A(1) adenosine receptors, decrease neuronal activity and thus the need for ...

Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy, 1990
Adenosine is a purine nucleoside present in every cell of the human body. It is released into the extracellular space under physiologic and pathophysiologic conditions characterized by increased oxygen demand: supply ratio. Adenosine can exert a wide spectrum of effects in various organs and tissues.

Adenosine, adenosine A2A antagonists, and Parkinson's disease
Parkinsonism & Related Disorders, 2009Adenosine derived from the degradation of ATP/AMP functions as a signalling molecule in the nervous system through the occupation of A1, A2, and A3 adenosine receptors. Adenosine A(2A) receptors have a selective localization to the basal ganglia and specifically to the indirect output pathway, and as a consequence offer a unique opportunity to modulate

The classic endogenous somnogen adenosine promotes sleep via A1 and A2A receptors. In this chapter, we present an overview of the current knowledge regarding the regulation of adenosine levels, adenosine receptors, and available pharmacologic and genetic tools to manipulate the adenosine system. This is followed by a summary of current knowledge of the

Regulation of adenosine kinase by adenosine analogs.
Molecular Pharmacology, 1988The regulation of adenosine phosphorylation by adenosine analogs was studied using highly purified human placental adenosine kinase [ATP: adenosine 5'-phosphotransferase (EC 2.7.1.20)]. Our observations lead us to classify the analogs into three groups as follows: type I, 5'-N-ethylcarboxamidoadenosine and 5'-methylthioadenosine; type II, N6 ...

Adenosine Diphosphate, Adenosine Triphosphate
1955The increasing importance for animals and bacteria of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) in energy-transfer mechanisms involving such widely diverse processes as muscular contraction, nerve conduction, fire fly luminescence, coenzyme syntheses, tumor growth, polysaccharide synthesis and many other key reactions (McElroy and ...

Immunohistochemistry of Adenosine Deaminase: Implications for Adenosine Neurotransmission
Science, 1984Immunohistochemical analysis of adenosine deaminase in rat brain revealed an extensive plexus of adenosine deaminase-containing neurons in the basal hypothalamus. These neurons converged on and were most numerous in three major centers, namely, the tuberal, caudal, and postmammillary caudal magnocellular nuclei.

Adenosine, adenosine receptors and glaucoma: An updated overview
Biochimica et Biophysica Acta (BBA) - General Subjects, 2013Glaucoma, a leading cause of blindness worldwide, is an optic neuropathy commonly associated with elevated intraocular pressure (IOP). The major goals of glaucoma treatments are to lower IOP and protect retinal ganglion cells. It has been revealed recently that adenosine and adenosine receptors (ARs) have important roles in IOP modulation and ...
