Esreboxetine
Esreboxetine ((S,S)-Reboxetine) is a selective norepinephrine transporter (NET) inhibitor, with a pIC50 of 9.6 and a pKi of 9.2 in rats, and it can cross the blood-brain barrier. Esreboxetine increases urethral closure pressure and urethral resistance in rats. Esreboxetine is applicable to research related to inflammatory pain and stress urinary incontinence.

In Vitro
Esreboxetine (10 pM-100 μM; 6 h) exhibits 20,000-fold higher selectivity for the rat norepinephrine transporter over the serotonin transporter in in vitro radioligand binding assays, with a pKi of 9.2 for rat NET and 5.6 for rat SERT[1].
Esreboxetine (10 pM-100 μM; 30 min pre-incubation, 6 min incubation) potently and selectively inhibits norepinephrine uptake in rat cortical synaptosomes, with a pIC50 of 9.6 for rat NET and a pIC50 of 5.3 for rat SERT, representing a 20,000-fold selectivity for NET over SERT[1].

-
Animal Model:Sprague-Dawley (adult male, 150-220 g, formalin-induced inflammatory pain model)[1]
-
Dosage:10 mg/kg (esreboxetine); 1 mg/kg (Fluoxetine)
-
Administration:i.p.; single dose
-
Result:Produced 24% inhibition of flinching behavior in the rat formalin model.
Achieved 78% NET and 55% SERT ex vivo transporter occupancy at 75 minutes post-dose.
Shifted the morphine dose-response curve leftward, reducing the morphine ED50 to 0.3 mg/kg, consistent with potentiation of morphine's antinociceptive effect.
