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

Biological Activity
Norfluoxetine (0.1-10 μM; 12-24 h) oxalate 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) oxalate 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) oxalate significantly attenuates nitric oxide and TNF release from lipopolysaccharide-activated primary rat microglia[2].
Norfluoxetine (10-30 μM) oxalate reduces protein levels in non-activated primary rat microglia in a dose-dependent manner[2].
Norfluoxetine (10-30 μM) oxalate reduces viability of non-activated primary rat microglia in a dose-dependent manner[2].
Norfluoxetine (10 μM) oxalate significantly increases the number of dead non-activated primary rat microglia, as measured by live/dead nuclear staining[2].
Norfluoxetine (10 μM) oxalate significantly increases the percentage of non-activated primary rat microglia expressing the apoptotic marker cleaved-caspase 3[2].
Norfluoxetine (10-20 μM; 24 h) oxalate 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) oxalate concentration-dependently inhibits voltage-gated Ca2+ channel-mediated Ba2+ currents in isolated rat cochlear neurons with an EC50 of 20.4 μM[3].
