生物活性

Levalbuterol ((R)-Albuterol) hydrochloride is a short-acting β2-adrenergic receptor agonist and the active (R)-enantiomer of Salbutamol. Levalbuterol hydrochloride is a more potent bronchodilator than Salbutamol and has the potential for the treatment of COPD[1].

體外研究
(In Vitro)

Levalbuterol (10 μM; 24 hours) hydrochloride induces 11β-HSD1 mRNA expression, however, it does not influence 11β-HSD2expression in airway epithelial cells[1].
Levalbuterol (10 μM; 24 hours) hydrochloride significantly reduces both LPS- and TNF-α-induced NF-κB activity while increasing GRE activation in an 11β-HSD1 dependent manner in a transformed mouse airway epithelial cell line[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

RT-PCR[1]

Cell Line: Murine Club (MTCC) cells
Concentration: 10 μM
Incubation Time: 24 hours
Result: Increased 11β-HSD1 mRNA expression selectively.
體內(nèi)研究
(In Vivo)

Levalbuterol (subcutaneous injection; 1 mg/kg; 14 days) hydrochloride significantly decreases pulmonary inflammation in OVA mice, demonstrated a decrease in eosinophilia and IgE[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6 female mice with a pulmonary allergic model[2]
Dosage: 1 mg/kg
Administration: Subcutaneous injection; 1 mg/kg; 14 days
Result: Decreased pulmonary inflammation after OVA sensitization.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
