Flindokalner
Based on 1 Customer Validation
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.

Biological Activity
Ki: 3.7 μM (Kv7.1), 230 μM (Kv7.4), 605 μM (Kv7.5)[1]
Flindokalner (BMS-204352) (10 μM) inhibits Kv7.4and Kv7.5 with Kis of 230 and 605 μM, respectively[1].
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[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In shock-based conditioned model of anxiety in male Wistar rats, Flindokalner (3-60 mg/kg; i.p.) engenderes an anxiolytic profile[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Female NMRI or male C57 mice (20-25 g) (Anxiolytic Models)[1]
-
Dosage:i.p.
-
Administration:3, 10, 30 mg/kg
-
Result:Significantly and dose dependently increased time spent in the open areas, reduced latency to enter an open area, and increased the number of entries in to the open areas in Zero Maze.

Solvent & Solubility
DMSO : 100 mg/mL (278.01 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.5 mg/mL (6.95 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Please enter the basic information of animal experiments:

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
