Biological Activity for Linopirdine dihydrochloride

Linopirdine dihydrochloride is a blocker of K_V7 (KCNQ) voltage-gated potassium channels; blocks K_V7.1 + 7.3 (KCNQ2 + 3) / M-currents (IC₅₀ = 4 - 7 μM) and K_V7.1 (KCNQ1) homomeric channels (IC₅₀ = 8.9 μM). Augments hippocampal ACh release and is a cognitive enhancer following oral administration in vivo.
