Pharmacological selectivity of AF-792

Receptor n pIC50 ± SEM
Rat P2X3 13 8.20 ± 0.06
Human P2X2/3 15 7.94 ± 0.08
Human P2X1 3 <5
Human P2X2 3 <5
Human P2X4 3 <5
Rat P2X5 3 <5
Human P2X7 3 <5

pIC50 values for all of the P2X channels were obtained from αβmeATP or ATP-evoked intracellular calcium flux in recombinant cell lines in the presence of AF-792.
