We examined the effect of the A3 adenosine receptor (AR) agonist IB-MECA on infarct size in an open-chest anesthetized dog model of myocardial ischemia-reperfusion injury. Dogs were subjected to 60 min of left anterior descending (LAD) coronary artery occlusion and
Multivalent dendrimeric conjugates of GPCR ligands may have increased potency or selectivity in comparison to monomeric ligands, a phenomenon that was tested in a model of cytoprotection in mouse HL-1 cardiomyocytes. Quantitative RT-PCR indicated high expression levels of endogenous A(1)
The sensitivity of cancer cells which exhibit multi-drug resistance phenotype to A3 adenosine receptor (A3AR) agonist N(6)-(3-iodobenzyl)-adenosine-5'-N-methylcarboxamide (IB-MECA) was studied. To establish direct relationship between P-glycoprotein (P-gp, ABCB1 and MDR1) expression and IB-MECA induced cell death, a straightforward method for

The adenosine A(3) receptor plays an important role in ischemic preconditioning. Activation of the adenosine A(3) receptor with its agonists induces both early and late pharmacological preconditioning through various mechanisms. As the first potent and selective adenosine A(3) receptor agonist
A3 adenosine receptor, A3AR, belongs to the Gi proteins coupled receptors. Activation of A3AR by its agonist, IB-MECA, decreases cAMP and was expected to reduce melanin level. Unexpectedly, B16 melanoma cells exposed to IB-MECA increased melanin levels in a dose-dependent
