5-BDBD inhibits 10 μM ATP-induced currents of rP2X4R-expressing HEK293 cells in a concentration-dependent manner, with an IC50 of 0.75 μM.
5-BDBD displaces rightward the ATP concentration-response curve, with an EC50 of 4.7 to 15.9 μM.
5-BDBD could be specifically used to discriminate between P2X1R, P2X2aR, P2X2bR, P2X3R, P2X4R, and P2X7R.
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
