Product Introduction

Bioactivity

Description	Formoterol fumarate (Eformoterol Hemifumarate), an effective, specific and long-acting β2-adrenoceptor agonist, is utilized in the treatment of chronic obstructive pulmonary disease(COPD) and asthma.
In vitro	In guinea pig lungs, Formoterol at a concentration of 100 mg/mL inhibits Platelet-Activating Factor (PAF)-induced eosinophil aggregation and suppresses Porcine Pancreatic Elastase (PPE) activity for 2-4 hours. In conscious guinea pigs, Formoterol dose-dependently inhibits histamine-induced plasma protein leakage and bronchoconstriction. Significant inhibition of histamine-induced effects was observed at doses of 10 mg/mL and 100 mg/mL. Additionally, a higher concentration of Formoterol is required to inhibit neutrophil aggregation (induced by Lipopolysaccharides) compared to its ability to suppress granulocyte-independent PPE (induced by histamine).
In vivo	Formoterol is a high-affinity, selective β2-adrenergic receptor agonist that effectively relaxes airway smooth muscles. Similar to salbutamol and salmeterol, it relaxes guinea pig trachea and human bronchi in vitro in a concentration-dependent manner and inhibits the release of antigen-induced inflammatory mediators in human lung slices.

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.
