Biological Activity for Linopirdine dihydrochloride

Linopirdine dihydrochloride is a blocker of KV7 (KCNQ) voltage-gated potassium channels; blocks KV7.1 + 7.3 (KCNQ2 + 3) / M-currents (IC50 = 4 - 7 μM) and KV7.1 (KCNQ1) homomeric channels (IC50 = 8.9 μM). Augments hippocampal ACh release and is a cognitive enhancer following oral administration in vivo.

Linopirdine proved to be a high quality Kv7 blocker and improves release of several neurotransmitters.
By Sadequl Islam on 10/22/2018
Assay Type: In Vitro
Species: Human

Our lab is working with Voltage gated potassium channel for a while and I have used a few potent Kv channel blockers to measure out the % blocking showed by them. This product gave reproducible data, stable in biological lab conditions and the work was published. So overall very happy with the purchase of the compound.
