Used primarily in research as a selective antagonist of adenosine A1 receptors, this compound helps investigate the role of adenosine signaling in physiological processes such as cardiac function, renal blood flow, and central nervous system activity. It is commonly employed in experimental models to study receptor binding, signal transduction, and the effects of adenosine modulation on cell function. Due to its selectivity, it serves as a pharmacological tool to differentiate A1 receptor-mediated effects from those involving other adenosine receptor subtypes.
