Adenosine receptor down-regulation and insulin resistance following prolonged incubation of adipocytes with an A1 adenosine receptor agonist.
Adenosine, via interaction with A1 adenosine receptors, increases insulin sensitivity and inhibits lipolysis in adipocytes. To investigate regulation of this system, adipocytes were incubated for up to 72 h with the nonmetabolizable adenosine receptor agonist, N6-phenylisopropyl adenosine (PIA). Adenosine receptors were measured by the binding of 125I-hydroxyphenylisopropyl adenosine to membran...
متن کاملAdenosine A1/A2a receptor agonist AMP-579 induces acute and delayed preconditioning against in vivo myocardial stunning.
The purpose of this study was to determine whether the adenosine A1/A2a receptor agonist AMP-579 induces acute and delayed preconditioning against in vivo myocardial stunning. Regional stunning was produced by 15 min of coronary artery occlusion and 3 h of reperfusion (RP) in anesthetized open-chest pigs. In acute protection studies, animals were pretreated with saline, low-dose AMP-579 (15 mic...
متن کاملAdenosine A1 receptors mediate chronic ethanol-induced increases in receptor-stimulated cyclic AMP in cultured hepatocytes.
Cellular responses to adenosine depend on the distribution of the two adenosine receptor subclasses. In primary cultures of rat hepatocytes, adenosine receptors were coupled to adenylate cyclase via A1 and A2 receptors which inhibit and stimulate cyclic AMP production respectively. R-(-)-N6-(2-phenylisopropyl)-adenosine (R-PIA), the adenosine A1 receptor-selective agonist, inhibited glucagon-st...
متن کاملPartial A1 adenosine receptor agonist regulates cardiac substrate utilization in insulin-resistant rats in vivo.
Reducing the availability and uptake of fatty acids is a plausible pharmaceutical target to ameliorate glucose intolerance and insulin resistance. CVT-3619 [2-{6-[((1R,2R)-2-hydroxycyclopentyl) amino]purin-9-yl(4S,5S,2R,3R)-5-[(2-fluorophenylthio)methyl]oxolane-3,4-diol] is a partial A(1) adenosine receptor agonist with antilipolytic properties. Aims of the present study were to examine the acu...
متن کاملAgonist-independent effect of an allosteric enhancer of the A1 adenosine receptor in CHO cells stably expressing the recombinant human A1 receptor.
The allosteric enhancer PD 81,723, a 2-amino-3-benzoylthiophene derivative, has been shown to potentiate agonist binding to A1 adenosine receptors (A1AdoRs) and to enhance the functional effects of adenosine and adenosine analogs. The objective of this study was to determine whether the apparent agonist-independent effect of PD 81,723 observed in CHO cells stably expressing the recombinant huma...
