DMPX

DMPX (3,7-dimethyl-1-propargylxanthine) is a caffeine analog which displays affinity for A₂ adenosine 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 agonist NECA. The locomotor stimulation caused by DMPX (ED₅₀ 10 μmol/kg) was similarly higher than caffeine.^[1]
