Product Introduction

Bioactivity

Description	SKA-111 is a selective calcium-activated potassium phannel (potassium phannel ) KCa3.1 activator that induces membrane hyperpolarization in porcine endothelial cells.SKA-111 binds to the interface between the CaM N-valve and the S4-S5 junction and ameliorates Bradykinin-induced dilation of coronary arteries in the isolated rat heart, which can be used for the study of cardiovascular diseases. study of cardiovascular diseases.
In vitro	SKA-111 (1 μM; 5 min) causes KCa3.1 membrane hyperpolarization in porcine endothelial cells. SKA-111 induces significantly enhanced Bradykinin-induced endothelium-derived hyperpolarization (EDH)-type relaxation in porcine large coronary arteries (PCA).[1]
In vivo	SKA-111 (1 μM; Cardiac perfusion; Langendorff in rat hearts; ) improves Bradykinin-induced coronary artery dilation in isolated rat hearts. SKA-111 potentiated significantly the fall in coronary perfusion pressure (CPP) induced by 1 nM BK in the presence of the vasoconstrictor in isolated rat hearts.[1]
Synonyms	SKA111, SKA 111

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

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.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
