An adenosine A3 receptor agonist (Ki = 1.7 nM); selective for adenosine A3 over A1 and A2 receptors (Kis = 55.3 and 3,099 nM, respectively); reduces wall thickening in a rabbit model of ischemia-reperfusion injury induced by coronary artery occlusion at 100 UG/kg; reduces hepatocellular tumor growth, liver inflammation, and neuropathy in a rat model of bone-residing breast cancer and the number of lung metastases in a model of metastatic murine melanoma; reduces colonic inflammatory cell infiltration and damage in a mouse model of DSS-induced colitis and in in IL-10-/- mice at 1 and 3 mg/kg
