Biological Activity

Description Reboxetine (PNU 155950E) is a norepinephrine reuptake inhibitor with Ki of 8.2 nM.
Targets
norepinephrine reuptake [1]
8.2 nM(Ki)
In vitro
In vitro Reboxetine dose-dependently and completely inhibits [3H]-dopamine uptake to the human norepinephrine transporters (hNET) with Ki value of 11 nM in Madin–Darby canine kidney (MDCK) cells. [1]
In Vivo
In vivo Reboxetine dose-dependently and potently inhibits locus coeruleus neuronal firing in rats with ED50 of 191 μg/kg. Reboxetine inhibition of the locus coeruleus neurons is reversible by the α2 antagonist piperoxan (1.5 mg/kg, IV). Reboxetine dose-dependently reverses reserpine-induced blepharospasm and hypothermia in the mouse. Reboxetine is also found to antagonize clonidine-induced hypothermia dose-dependently in mice. Reboxetine reverses reserpine-induced blepharospasm and hypothermia in rats with ED50 of 10 mg/kg and 3 mg/kg (p.o.), respectively. [1] Reboxetine results in a significant reduction in the mean number of panic attacks and phobic symptoms in patients with DSM-III-R panic disorder. Reboxetine also results in improvement in Hamilton Rating Scale for Depression, Hopkins Symptom Checklist-90, and Sheehan Disability Scale scores. [2] Reboxetine is associated with a markedly lower relapse rate than placebo (22% vs. 56%) and a greater cumulative probability of a maintained response during long-term treatment in patients with recurrent DSM-III-R major depression. Reboxetine effectively prevents recurrence of depressive symptoms following episode resolution. [3] Acute systemic administration of Reboxetine (0.3 mg/kg-20 mg/kg) dose-dependently increases extracellular norepinephrine in the rat frontal cortex while having no effect on extracellular serotonin. Reboxetine (20 mg/kg) also increases extracellular dopamine in the rat frontal cortex. Chronic administration of Reboxetine for 14 days results in elevated basal concentrations of extracellular norepinephrine and dopamine and a greater net increase of extracellular norepinephrine and dopamine, but not serotonin in the rat frontal cortex. [4] Reboxetine dose dependently decreases nicotine self-administration by ~60%. Repeated administration of Reboxetine (5.6 mg/kg) decreases nicotine self-administration and sucrose-maintained responding across the 14 sessions. [5]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
