Description

IC₅₀ & Target

IC50: 0.26 μM (hGAT-1); 1.2 μM (rGAT-1); 297 μM (rGAT-2); 333 μM (hGAT-3); 1140 μM (rGAT-3); 300 μM (hBGT-3)^[1]

In Vitro

CI-966 hydrochloride functions by selectively inhibiting GABA reuptake in neurons and glial cells^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

CI-966 hydrochloride produces intermediate levels of Pentylenetetrazol (PTZ)-lever responding when administered to PTZ-trained rats^[4].
CI-966 hydrochloride enhances gamma-aminobutyric acid action in CA1 pyramidal layer in situ. CI-966 hydrochloride is administered systemically by i.p. injection (5 mg/kg) in Sprague-Dawley rats under urethane anaesthesia. Twenty to thirty minutes after injection there is a highly variable, but overall significant, enhancement of the inhibition of hippocampal population spikes by GABA applied by microiontophoresis in the CA1 region^[5].
CI-966 hydrochloride exhibits anticonvulsant properties in various animal models. Oral absorption of CI-966 hydrochloride in dogs given 1.39 mg/kg is rapid with a t_max of 0.7 hr. In rats given 5 mg/kg oral, a mean t_max of 4.0 hr is observed. Following i.v. administration of the same respective doses, elimination t_1/2 in dogs and rats averages 1.2 and 4.5 hr. Absolute oral bioavailability of CI-966 hydrochloride is 100% in both species^[6].

Animal Model:	Eight male Sprague-Dawley rats^[4]
Dosage:	0.3-30 mg/kg
Administration:	Injection IP in a volume of 1 mL/kg
Result:	Dose dependent decreases in rates of responding occurred following CI-966 administration.

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (4.90 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
