Biological Data

Biological description

PPADS tetrasodium salt is a non-selective purinergic P2 receptor antagonist (IC50 values are 1-4 µM at recombinant P2X1, P2X2, P2X3, and P2X5, P2X7 and 28 µM at P2X4 receptors).

PPADS also blocks P2Y1-like and P2Y1 receptors coupled to PLC (pA2 = 6), some P2Y2-like and P2Y4 receptors (IC50 values are 0.9 and 15 µM respectively).

PPADS shows a variety of biological actions. Active in vivo.
