TNP-ATP (tetrasodium)
TNP-ATP is an antagonist of purinergic P2Y1, P2X3, and P2X2/3 receptors (IC50 = 6, 0.9, and 7 nM, respectively, in HEK293 cells expressing human receptors) . TNP-ATP reduces acetate-induced calcium flux in 1321N1 cells expressing P2X3 and P2X2/3 receptors (IC50 = 100 and 62 nM, respectively) . TNP-ATP dose-dependently attenuates acetate-induced abdominal contractions in a mouse visceral pain model (ED50 = 6.35 µmol/kg) [1][2].
