PD 81,723 is an allosteric potentiator that increases the functional effects of adenosine and adenosine analogs.

Allosteric potentiator at the adenosine A 1 receptor; acts via agonist-dependent and -independent mechanisms. Enhances agonist affinity for, and increased t 1/2 of dissociation from, the receptor. Also inhibits basal and forskolin-stimulated adenylyl cyclase (AC) activity in A 1 receptors expressed in CHO cells, possibly via direct potentiation of constitutive receptor activity or by direct inhibition of AC. Active in vivo .
