Lea Madi et al.
Experimental dermatology, 22(1), 74-77 (2012-10-24)
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
Vijay B Urmaliya et al.
Journal of cardiovascular pharmacology, 53(5), 424-433 (2009-04-01)
Extracellular adenosine concentrations increase within the heart during ischemia, and any exogenous adenosine receptor agonists therefore work in the context of significant local agonist concentrations. We evaluated the interactions between A1, A2A, A2B, and A3 receptors in the presence and
Michal Hofer et al.

Research areas of 'post-exposure treatment' and 'cytokines and growth factors' have top priority among studies aimed at radiological nuclear threat countermeasures. The experiments were aimed at testing the ability of N(6)-(3-iodobenzyl)adenosine-5'-N-methyluronamide (IB-MECA), an adenosine A(3) receptor agonist, to modulate hematopoiesis
Jorge Guzman et al.
Inflammatory bowel diseases, 12(8), 766-789 (2006-08-19)
Adenosine A3 receptors (ADOA3Rs) are emerging as novel purinergic targets for treatment of inflammatory diseases. Our goal was to assess the protective effect of the ADOA3R agonist N(6)-(3-iodobenzyl)-adenosine-5-N-methyluronamide (IB-MECA) on gene dysregulation and injury in a rat chronic model of

Neoplasia (New York, N.Y.), 11(11), 1132-1145 (2009-11-03)
Prostate cancer is the most commonly diagnosed and second most lethal malignancy in men, due mainly to a lack of effective treatment for the metastatic disease. A number of recent studies have shown that activation of the purine nucleoside receptor
