生物活性 for XE 991 dihydrochloride
XE 991 dihydrochloride is a potent and selective blocker of KV7 (KCNQ) voltage-gated potassium channels. Blocks KV7.2+7.3 (KCNQ2+3) / M-currents (IC50 = 0.6 - 0.98 μM) and KV7.1 (KCNQ1) homomeric channels (IC50 = 0.75 μM) but is less potent against KV7.1/minK channels (IC50 = 11.1 μM). Augments hippocampal ACh release and is a cognitive enhancer following oral administration in vivo.

XE 991 is a potent Kv7 channel blocker.My study focused on to finding out whether it shows the same blocking effect on Kv11.1 channels. The product worked ideally in lab coditions, produced reproducible data. Would purchase again.
