PSB 36 is a potent and selective Adenosine A1-R antagonist. PSB 36 displays binding affinities of 0.12, 187, 552, 6500 and 2300 nM for rat Adenosine A1-R, human Adenosine A2B-H, rat Adenosine A2A-R, rat Adenosine A3-R and human Adenosine A3-H, respectively. This compound demonstrates greater selectivity than DPCPX.
