Product Introduction

Bioactivity
Description
Clamikalant sodium (HMR 1098) is an ATP-dependent potassium channel (KATP) cardiac-selective blocker, used in the study of arrhythmias.
Targets&IC50
sK (ATP):0.36 mM
In vitro
Clamikalant sodium is a selective sarcosine K (ATP) channel inhibitor. It blocks the sK (ATP) current (IC (50) =0.36 mM) induced by the K (ATP) opener pinacidil. [1]
In mouse atrial myocytes, both spontaneous activation and diazine-activated K (ATP) currents were effectively inhibited by 10 μM Clamikalant sodium. In contrast, in ventricular myocytes, high concentrations of Clamikalant sodium (100 μM) inhibited the K (ATP) current activated by the pinate, but low concentrations (10 μM) did not. Consistent with this finding, in COSm6 cells, Clamikalant sodium inhibits (86) Rb (+) efflux through Kir6.2/SUR1 more effectively than the Kir6.2/SUR2A channel. [2]
In vivo
Clamikalant sodium treatment (3 mg/kg push followed by continuous intravenous injection at 17 μg/kg/min throughout the study) did not prevent the shortening of HRA-ERP and the flattening or inversion of ERP rate adaptation in dogs. [3]

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.
