Product Introduction

Bioactivity

Description	NS3623 is an activator of human ether-a-go-go-related gene (hERG) potassium channels with a dual mode of action, also acting as an inhibitor of hERG1 channels. It activates the IKr and Ito currents and exhibits an antiarrhythmic effect.
In vitro	Administering NS3623 (5 μM) significantly enhances the tail current magnitude in isolated canine cardiomyocytes, corroborating earlier evidence that this compound augments IKr. Specifically, NS3623 boosts IKr tail currents by 60% in normal Mid cells and by 68% in cells cultured for 48 hours, at a +50 mV activating pulse. Furthermore, although the baseline IKr in cells cultured for 48 hours markedly declines compared to freshly isolated cells—from 0.47 ± 0.08 pA/pF to 0.28 ± 0.06 pA/pF—NS3623 application elevates IKr in these cultured Mid cells. An analysis of the current-voltage (I-V) relationship for IKr tail current reveals that NS3623 increases current density in Mid cells cultured for both one and two days.
In vivo	NS3623 (30 mg/kg; i.v.; lasting for 3 minutes) shortens the corrected QT interval by 25 ± 4% in anaesthetized guinea pigs. At 50 mg/kg, NS3623 immediately reduces the QTcF interval and remains significantly shortened for approximately 30 minutes, also shortening the QT interval by 30 ± 6% in conscious guinea pigs [1].

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
