Norfluoxetine
Based on 1 Customer Validation
Norfluoxetine is the active metabolite of the antidepressant Fluoxetine (HY-B0102); it is also a TREK-2 K2P potassium channel inhibitor. Norfluoxetine exhibits neuroimmunological activity, induces apoptosis in primary microglial cells, and inhibits the release of pro-inflammatory factors. Norfluoxetine inhibits high-threshold voltage-gated Ca2+ currents in neurons with an EC50 of 20.4 μM. Norfluoxetine can be used in research related to depression, ischemic stroke, and epilepsy.

Norfluoxetine (0.1-10 μM; 12-24 h) inhibits full-length human TREK-2 channels expressed in Xenopus laevis oocytes with an IC50 of 2.7 μM at +40 mV; inhibition is reduced by TPA and ML335 but not by tetraethylammonium or 2-APB[1].
Norfluoxetine (10-100 μM) reduces single-channel open probability, current amplitude, mean open time, and mean short closed time of truncated human TREK-2 channels reconstituted in lipid bilayers, with increased inhibitory efficacy at voltages above +60 mV, and exhibits similar inhibitory efficacy in high-Po and standard gating modes[1].
Norfluoxetine (10 μM) significantly attenuates nitric oxide and TNF release from lipopolysaccharide-activated primary rat microglia[2].
Norfluoxetine (10-30 μM) reduces protein levels in non-activated primary rat microglia in a dose-dependent manner[2].
Norfluoxetine (10-30 μM) reduces viability of non-activated primary rat microglia in a dose-dependent manner[2].
Norfluoxetine (10 μM) significantly increases the number of dead non-activated primary rat microglia, as measured by live/dead nuclear staining[2].
Norfluoxetine (10 μM) significantly increases the percentage of non-activated primary rat microglia expressing the apoptotic marker cleaved-caspase 3[2].
Norfluoxetine (10-20 μM; 24 h) induces apoptosis in non-activated primary rat microglia by increasing cleaved-caspase 3 and decreasing full-length caspase 3, without altering caspase 8 levels[2].
Norfluoxetine (1-100 μM; 30 s) concentration-dependently inhibits voltage-gated Ca2+ channel-mediated Ba2+ currents in isolated rat cochlear neurons with an EC50 of 20.4 μM[3].

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 (8.47 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.
