PPADS (pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid) is a selective purinergic P2X antagonist.^[2] It is able to block contractions of rabbit vas deferens induced by ATP or α,β,methylene-ATP. It appears to be relatively selective for P2X receptors, having no appreciable activity at α₁ adrenergic, muscarinic M₂ and M₃, histamine H₁, and adenosine A₁ receptors.^[3]
