XE991 is a novel and selective Kv7 (KCNQ) channel blocker.XE 991 dihydrochloride inhibits Kv7.1 (KCNQ1), Kv7.2 (KCNQ2), Kv7.2 + Kv7.3 (KCNQ3) channels, and M-current, and can be used for the study of neurological diseases.

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 μM, 0.71 μM, 0.6 μM, and 0.98 μM, respectively).

Linopirdine (DuP 996) is a TRPV1 agonist. Linopirdine is an orally active and selective M-type K+ current (IM; Kv7; KCNQ Channels) inhibitor (IC50: 2.4 μM). Linopirdine is a cognitive enhancer. It acts by stimulating release of acetylcholine and other neurotransmitters.Linopirdine is a putative cognition-enhancing drug that increases acetylcholine release in rat brain tissue.

Flindokalner (BMS-204352) is a potassium channel modulator and a positive modulator of all neuronal Kv7 channel subtypes expressed in HEK293 cells. It is also a positive modulator of large conductance calcium-activated K channels (BKca) and displays negative modulatory activity at Kv7.1 channels (Ki = 3.7 μM). Additionally, Flindokalner acts as a negative modulator of GABAA receptors and demonstrates anxiolytic efficacy in vivo.

PF05020182 is novel potent and selective Kv7.2/4 potassium channel opener. PF-05020182 (2) significantly inhibits convulsions in the MES assay at doses tested, consistent with in vitro activity measure. The physiochemical properties, in vitro and in vivo activities of PF-05020182 support further development as an adjunctive treatment of refractory epilepsy. Facilitating activation, or delaying inactivation, of the native Kv7 channel reduces neuronal excitability, which may be beneficial in controlling spontaneous electrical activity during epileptic seizures.

QO-58 is a Kv7 channel opener with EC50 values of 7.0, 1.0, 5.2, 0.6 μM for Kv7.1, Kv7.2, Kv7.3/7.5, Kv7.4 respectively. QO-58 increases the pain threshold of neuropathic pain in a sciatic nerve CCI in vivo.

KV7 (KCNQ) voltage-gated potassium channels blocker

DMP-543 (XR-543) is a KV7 channel blocker that enhances neurotransmitter release.
