Fenoterol (Th-1165a; Phenoterol hydrobromide), a potent β2 adrenergic agonist designed to open up the airways to the lungs, is classed as sympathomimetic beta agonist and asthma medication.
| Targets |
β2 adrenoreceptor
|
|---|---|
| ln Vitro |
Fenoterol (1 μM; pre-incubated 30 minutes) treatment significantly downregulates the elevated phosphorylation levels of AMPK and reduces AICAR-induced NF-κB activation, TNF-α release, and AMPK activation[2].
Fenoterol suppresses the production of inflammatory cytokines and AMPK activation caused by lipopolysaccharide (LPS) in THP-1 cells[2]. Fenoterol is also a strong inducer of exosome biogenesis and/or secretion in PC cells[4]. |
| ln Vivo |
Fenoterol (0.7 mg/kg; intraperitoneal injection; twice a day; for 3 weeks) suppresses mechanical allodynia during chronic treatment[3].

| Additional Infomation |
Fenoterol belongs to the resorcinol class of compounds. Its chemical name is 5-(1-hydroxyethyl)benzene-1,3-diol, in which one methyl hydrogen atom is replaced by 1-(4-hydroxyphenyl)prop-2-amino. It is a β2-adrenergic agonist, used as a bronchodilator in the form of hydrobromide for the treatment of reversible airway obstruction. It has multiple effects as a bronchodilator, sympathomimetic agent, β-adrenergic agonist, and tocolytic. It is a secondary amino compound, a secondary alcohol, and also a resorcinol. Fenoterol is a β2-adrenergic agonist that can be used as a bronchodilator and tocolytic. Fenoterol is a short-acting sympathomimetic agent with bronchodilatory effects. Fenoterol stimulates β2-adrenergic receptors in the lungs, thereby activating adenylate cyclase, an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic adenosine monophosphate (cAMP). Increased cAMP levels can relax bronchial smooth muscle, relieve bronchospasm, and reduce the release of inflammatory cytokines, especially those from mast cells. Fennoterol is a synthetic β2-adrenergic agonist used as a bronchodilator and a tocolytic. Drug Indications: Fennoterol is used to treat asthma. Mechanism of Action: Pulmonary β2-receptor agonists cause bronchial smooth muscle relaxation, bronchodilation, and increased bronchial airflow. Pharmacodynamics: Fennoterol is a β-receptor agonist designed to open lung airways by reducing bronchial constriction.

| Solubility (In Vitro) |
DMSO: ~100 mg/mL (~329.7 mM)

|---|---|
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (8.24 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (8.24 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.3296 mL | 1.6482 mL | 3.2964 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
