Description
(extracted from source data)
DESCRIPTION XE991 dihydrochloride, a Kv7 (KCNQ) channels blocker, potently inhibits Kv7.1 (KCNQ1), Kv7.2 (KCNQ2), Kv7.2 + Kv7.3 (KCNQ3) channel, and M-current with IC50s of 0.75 ¦ÌM, 0.71 ¦ÌM, 0.6 ¦ÌM, and 0.98 ¦ÌM, respectively[1].

DESCRIPTION XE 991 dihydrochloride is a Kv7 (KCNQ) channel blocker. XE 991 dihydrochloride potently inhibits Kv7.1 (KCNQ1), Kv7.2 (KCNQ2), Kv7.2 + Kv7.3 (KCNQ3) channel, and M-current (IC50s: 0.75 ??M, 0.71 ??M, 0.6 ??M, and 0.98 ??M, respectively).
DESCRIPTION XE 991 dihydrochloride is a potent and selective blocker of KV7 (KCNQ) voltage-gated potassium channels. XE 991 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). XE 991 increases hippocampal ACh release and enhances cognition following oral administration in vivo, suggesting to be beneficial for Alzheimer's disease therapy. (BOC Sciences Bioactive Compounds)
