MRS1523 is a selective adenosine A3 receptor antagonist (Kis = 18.9 and 113 nM for human and rat A3 receptors, respectively, versus Kis = 15.6 and 2.05 μM for rat A1 and A2A receptors, respectively). As activation of the A3 receptor is linked to several second messenger systems for signaling pathways involving inflammatory, asthmatic, and ischemic responses, this selective antagonist may be useful in characterizing the various functions of the receptor.
