Beschreibung

General description

A suramin analog that acts as a highly selective, competitive, and reversible ATP-antagonist of P2X receptor (IC₅₀/K_B ~1 µM in smooth muscle). Effectively discriminates between P2Y and P2X receptors with no discernible effects on α_1A adrenoceptors, adenosine A₁ and A_2B receptors, histamine H₁, muscarinic M₃ and neuronal nicotinic acetylcholine receptors. Displays a selectivity profile of P2X₁ >P2X₂ >P2X₃ >P2X₄ (IC₅₀ = 19 nM, 770 nM, 1.62 µM and >300 µM, respectively) in Xenopus oocytes pre-incubated with ATP. In rat and human tissues, exhibits a potency profile of rat P2X₁ > human P2X₁ » rat P2X₂ > rat P2X₃ ~human P2X₇ » human P2X₄. Not degraded by ecto-nucleotidases.
