Biological Activity for PD 81723

PD 81723 is an allosteric potentiator at the adenosine A₁ receptor; acts via agonist-dependent and -independent mechanisms. Enhances agonist affinity for, and increased t_½ of dissociation from, the receptor. Also inhibits basal and forskolin-stimulated adenylyl cyclase (AC) activity in A₁ receptors expressed in CHO cells, possibly via direct potentiation of constitutive receptor activity or by direct inhibition of AC. Active in vivo.
