Levalbuterol ((R)-Albuterol; (R)-Salbutamol) 是短效 β2-肾上腺素受体 (β2-adrenergic receptor) 激动剂和 Salbutamol 的活性 R 型对映异构体。Levalbuterol 是一种比 Salbutamol 更有效的支气管扩张试剂，可用于哮喘和慢性阻塞性肺疾病 (COPD) 的研究。
Levalbuterol (10 μM; 24 hours) induces 11β-HSD1 mRNA expression, however, it does not influence 11β-HSD2 expression in airway epithelial cells.Levalbuterol (10 μM; 24 hours) 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.
RT-PCR
| Cell Line: | Murine Club (MTCC) cells |
| Concentration: | 10 μM |
| Incubation Time: | 24 hours |
| Result: | Increased 11β-HSD1 mRNA expression selectively. |
Levalbuterol (subcutaneous injection; 1 mg/kg; 14 days) significantly decreases pulmonary inflammation in OVA mice, demonstrated a decrease in eosinophilia and IgE.
| Animal Model: | C57BL/6 female mice with a pulmonary allergic model |
| Dosage: | 1 mg/kg |
| Administration: | Subcutaneous injection; 1 mg/kg; 14 days |
| Result: | Decreased pulmonary inflammation after OVA sensitization. |
