Biological Activity for PSB 36

PSB 36 is a potent and selective A1 adenosine receptor antagonist. PSB 36 displays binding affinities of 0.12, 187, 552, 6500 and 2300 nM for rA1, hA2B, rA2A, rA3 and hA3 receptors respectively. PSB 36 demonstrates greater selectivity than DPCPX (Cat. No. 0439). PSB 36 reduces atrial fibrillation in rat isolated beating heart preparations.
