Iso-PPADS tetrasodium salt is a specific P2 purinoceptors antagonist [3].
P2 purinoceptors mediate the actions of adenosine 5'-tri- phosphate (ATP) on many physiological systems including most vascular and visceral smooth muscles and certain neur- ones in the peripheral and central nervous systems
IsoPPADS (10 uM) depressed alpha, beta-Me-ATP-evoked depolarizations but did not alter depolarizations evoked by UTP. So it is concluded that IsoPPADS is antagonist at P2x-purinoceptor but not at the receptor that mediate UTP-evoked depolarization of the rat superior cervical ganglion [1]. In functional studies, iso-PPADS identified two populations of [3H]alpha,beta-meATP binding sites, 26.4% of these having low affinity (pKi of 4.4 +/- 0.2), and 73.6% having high affinity (pKi of 6.5 +/- 0.02) for iso-PPADS [2]. Iso-PPADS (1 X 10-6 -1 X 10-5 M) produced a concentration-related depression in the maxima of the concentration-effect curves to alpha,beta-methylene ATP. The antagonistic effect of iso-PPADS (1 x 10-5 M) was partially attenuated by suramin (1 x 10-4 M) and this interaction reflects a slow dissociation of iso-PPADS from the receptor with which suramin and alpha, beta-methylene ATP interact [3].
