DMPX (3,7-dimethyl-1-propargylxanthine) is acaffeineanalog which displays affinity for A2adenosine receptors, in contrast to the A1 subtype receptors.[1] DMPX had 28 times and 15 times higher potency than caffeine in blocking, respectively, the peripheral and central effects of the adenosine agonistNECA. The locomotor stimulation caused by DMPX (ED50 10μmol/kg) was similarly higher than caffeine.[1]
