kv7.4

ZTZ240 is a KCNQ2 channel activator used in the study of epilepsy.

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.

NC00075159 is an opener of human KCNQ4 (Kv7.4) potassium channel.

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.

ML213 (CID-3111211) is a selective activator of Kv7.2 (KCNQ2) and Kv7.4 (KCNQ4) channels, enhances Kv7.2 and Kv7.4 channels with EC50s of 230 and 510 nM, respectively.

ML 297 is a selective Kir3.1 3.2 (GIRK1 2) channel activator (IC50 values are 160, 887 and 914 nM for GIRK1 2, GIRK1 4 and GIRK1 3 respectively). ML 297 exhibits no effect on GIRK2, GIRK2 3, Kir2.1 and Kv7.4 channels, and has minimal effect on a panel of other ion channels, receptors and transporters.

Ssm Spooky Toxin, derived from Scolopendra mutilans, exhibits potent lethality affecting both hematological and respiratory systems primarily through the inhibition of KCNQ (voltage-gated potassium channel family 7) channels. It demonstrates IC50 values of 2.8 μM for Kv7.4, 5.26 μM for Kv1.3, and 0.1-0.3 M for the Shal channel, respectively. Additionally, this toxin impedes cytokine production by selectively targeting the KV1.3 channel in T cells and is crucial for the centipede's circulatory system functions [1] [2] [3].

Bimokalner (Bimokalnerum) is an activator of the voltage-gated potassium channel (Kv7.4).
