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.

The glycoprotein nature of A1 adenosine receptors [PDF]

open access: possibleBiochemical and Biophysical Research Communications, 1986
A1 adenosine receptors from different tissues and species were photoaffinity labelled and then the carbohydrate content was examined by both enzymatic and chemical treatment. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the labelled membrane receptors shows that neuraminidase treatment alters the electrophoretic mobility of the receptor

Allosteric modulators for the A1 adenosine receptor

Expert Opinion on Therapeutic Patents, 2004
The present invention provides compounds of formula (I) wherein R1, R2, R3, R4 and Q have a meaning as defined herein in the specification. The compounds of formula (I) are allosteric modulators of the A1 adenosine receptor and, thus, may be employed for the treatment of conditions mediated by the A1 adenosine receptor.

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

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 ...

Binding thermodynamics at A1 and A2a adenosine receptors

Life Sciences, 1996
Only recently the binding equilibrium of a number of ligands at adenosine A1 and A2a receptors has been analyzed from a thermodynamic point of view. This approach presents the advantage, with respect to usual affinity constant measurements, of a greater capability to give information about the molecular mechanisms underlying the binding process.

The role of adenosine A1 receptor on immune cells

Inflammation Research, 2022
Adenosine, acting as a regulator by mediating the activation of G protein-coupled adenosine receptor families (A1, A2A, A2B, and A3), plays an important role under physiological and pathological conditions. As the receptor with the highest affinity for adenosine, the role of adenosine A1 receptor (A1R)-mediated adenosine signaling pathway in the ...
