产品详情
Levalbuterol ((R)-Albuterol) hydrochloride 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 hydrochloride 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。
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.

Solid
体外研究(In Vitro)
Levalbuterol (10 μM; 24 hours) hydrochloride induces 11β-HSD1 mRNA expression, however, it does not influence 11β-HSD2 expression in airway epithelial cells.
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. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(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. has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model:

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
