Product Introduction

Bioactivity
Description
Istaroxime hydrochloride (PST2744 hydrochloride) is a Na+/K+-ATPase inhibitor and sarcoplasmic/endoplasmic reticulum calcium ATPase 2 (SERCA 2) activator, a novel positive inotropic compound that can be used to study acute heart failure.
Targets&IC50
Na+, K+-ATPase:0.11 μM, Na+/K+-ATPase (dog kidney):0.43 μM, Na+/K+-ATPase (guinea-pig kidney):8.5 μM
In vitro
Istaroxime hydrochloride acts as a positive inotropic drug by inhibiting Na+,K+-ATPase. [1]
The IC50 value of Istaroxime hydrochloride for inhibition of Na+/K+-ATPase activity in dog kidney was 0.43 μM. In guinea-pig kidney tissue preparations, the potency of Istaroxime hydrochloride for inhibition of Na+/K+-ATPase activity was 8.5 μM. [2]
In vivo
Istaroxime hydrochloride progressively elevated +dP/dtmax throughout the infusion period, achieving an 80% effect at a cumulative dose of 1.89 ± 0.37 mg/kg (ED80) and reaching a peak effect of 140 ± 3.5% at a dose increase to 4.88 ± 0.6 mg/kg (EDmax). [2]

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.
