Product Introduction

Bioactivity
Description
Vernakalant Hydrochloride (RSD1235 hydrochloride) is a mixed voltage- and frequency-dependent Na+ and atria-preferred K+ channel blocker.
Targets&IC50
Kv1.5 channel (T479A):1.63±0.09 μM, I508F:0.61±0.03 μM, Kv1.5 channel (WT):13.35±0.93 μM
In vitro
Block of Kv1.5 by Vernakalant Hydrochloride occurs after channel activation, as Vernakalant induces a rapid block of channel current upon depolarization with minimal resting or “tonic” block. The most significant effect is the reduction in potency at I502A, with an IC50 of 329±19 μM (n=4-10) compared to a control IC50 of 13.4±0.9 μM (n=5-23), reflecting a 25-fold potency decrease. Lesser reductions in potency, between 3- and 4-fold, were noted for V505A, I508A, T480A, and C500A. For wild-type and mutant Kv1.5 channels, IC50 for Vernakalant block are 13.35±0.93 μM, 0.61±0.03 μM, and 1.63±0.09 μM for Kv1.5 channels, Kv1.5 channelI508F, and Kv1.5 channelT479A, respectively [1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
