Adenosine A1 receptors and erythropoietin production

American Journal of Physiology-Cell Physiology, 1993
N6-cyclopentyladenosine (CPA), a selective adenosine A1 receptor agonist, in a concentration range of 10(-9) to 10(-7) M, produced a significant decrease in erythropoietin (EPO) levels in a human hepatocellular carcinoma (Hep G2) cell culture (medium levels of EPO, 91.81 +/- 1.61 and 94.36 +/- 0.97% of control, respectively) after 24 h incubation in a

Adenosine receptor modelling. A1/A2a selectivity

European Journal of Medicinal Chemistry, 2006
Three-dimensional models of the A(1) and A(2a) adenosine receptors (AR) were constructed by means of a homology procedure, using bovine rhodopsin as a template. In order to validate the two models, a docking analysis of selective agonists was carried out.

Allosteric modulators for the A1 adenosine receptor

Expert Opinion on Therapeutic Patents, 2004
A review. Allosteric modulators of endogenous adenosine represent an alternative to direct acting adenosine agonists and nucleoside uptake blockers. These compds. can selectively enhance the response to adenosine in only those organs or localized areas of a given organ in which prodn. of adenosine is increased. The present article is an overview of the

Adenosine A1 receptor antagonists and the kidney

Current Opinion in Nephrology and Hypertension, 2003
This review will examine the most recent evidence that adenosine receptors in the kidney can alter kidney function. Adenosine A(1)-receptors located in the afferent arteriole and proximal tubule can contribute to fluid retaining disorders by mediating tubuloglomerular feedback, afferent arteriole vasoconstriction or direct sodium absorption.

Medicinal Chemistry of Adenosine A1 Receptor Ligands

Current Topics in Medicinal Chemistry, 2003
In this review the latest developments in ligand design for the adenosine A(1) receptor are summarized. Novel series of agonists and antagonists are discussed, leading to the conclusion that ligands truly selective for the human adenosine A(1) receptor are still scarce.

Allosteric Enhancers for A1 Adenosine Receptor

Mini-Reviews in Medicinal Chemistry, 2007
Allosteric enhancers at the adenosine A(1) receptor have received attention as anti-arrhythmic cardiac agents, and, more recently, as anti-lipolytic agents. In addition, allosteric modulators at the adenosine A(1) receptor have therapeutic potential as analgesics and neuroprotective agents.

Binding of an adenosine A1 receptor agonist and adenosine A1 receptor antagonist to sheep pineal membranes

European Journal of Pharmacology, 1997
The pineal organ of vertebrates produces melatonin and adenosine. In lower vertebrates, adenosine modulates melatonin production. We report herein that 2-chloro-cyclopentyl-[3H]-adenosine ([3H]CCPA: adenosine A1 receptor agonist) and [3H]-cyclopentyl-1,3-dipropylxanthine ([3H]DPCPX: adenosine A1 receptor antagonist), bind specifically to sheep pineal ...
