Disclosed are novel methods of antagonizing the A3 adenosine receptor in a mammal, comprising administering to a mammal in need thereof a therapeutically effective dose of a compound of the formula: wherein R is hydrogen or acyl; R1 is hydrogen, halo, optionally substituted C1-4 alkyl, optionally substituted alkenyl, optionally substituted aryl, or optionally substituted heteroaryl; R2 is optionally substituted C1-4 alkyl; Y is C1-4 alkylene; and Z is phenyl, optionally substituted with halo, optionally substituted C1-4 alkyl, or C1-4 alkoxy. The A3 adenosine receptors may be antagonized in order to treat a disease state is chosen from renal failure, nephritis, hypertension, oedemas, Alzheimers disease, stress, depression, cardiac arrhythmia, restoration of cardiac function, asthma, respiratory disorders, ischemia-induced injury of the brain, heart and kidney, and diarrhea. Preferred compounds selectively antagonize A3 adenosine receptors over A1 adenosine receptors, A2A adenosine receptors and A2B adenosine receptors.
