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

How to use

In Vitro:

Flindokalner (BMS-204352) (10 μM) inhibits Kv7.4and Kv7.5 with Kis of 230 and 605 μM, respectively. Flindokalner (1-10 μM) causes inhibition of the Ca2+ current in a dose-dependent manner, with a Kd of 6 μM and a Hill coefficient of 1.33. Flindokalnerinhibits cardiac L-type Ca2+ channels in a direct manner, without affecting BKCa channels or intracellular signal transduction, in freshly isolated rat ventricular myocytes.

In Vivo:

Flindokalner (BMS-204352) (3-30 mg/kg; i.p.) induces a dose-dependent anxiolytic effect. In shock-based conditioned model of anxiety in male Wistar rats, Flindokalner (3-60 mg/kg; i.p.) engenderes an anxiolytic profile.
