Application
XE-991 has been used as a KCNQ (Kv7.2/7.3) inhibitor to examine whether M-current inhibition affects oxytocin receptor (TGOT) mediated depolarization. It has also been used as an KCNQ inhibitor to study the ionic mechanism responsible for the overshoot/undershoot in membrane potential in mouse cholinergic interneurons (ChIs) in the presence of tetrodotoxin (TTX).
Biochem/physiol Actions
XE-991 is a KCNQ channel blocker.
XE-991 is a KCNQ channel blocker; which is more potent than linopiridine (Cat. No. L-134).
