生物活性

Tulobuterol hydrochloride (C-78) is a long-acting β2-adrenoceptor agonist, which reduces the frequency of exacerbations of chronic obstructive pulmonary disease and bronchial asthma. Tulobuterol hydrochloride is also a sympathomimetic agent used as a transdermal patch, increases normal diaphragm muscle strength[1]. Tulobuterol hydrochloride inhibit rhinovirus replication and modulate airway inflammation[2].

IC50 & Target

β2-adrenoceptor[1]

体外研究
(In Vitro)

Tulobuterol (0.1 μM; 24 hours or 72 hours; human tracheal epithelial cells) treatment decreases the RV14 RNA levels at 1 day and at 3 days after infection. The concentrations of sICAM-1 in the supernatants of the cells treated with tulobutero are significantly lower than those in the cells treated with vehicle before RV14 infection. Treatment with tulobuterol reduces the number of acidic endosomes with green fluorescence in the cells and the fluorescence intensity of acidic endosomes in the cells. Also reduces the RV14 infection-induced secretion of IL-1β, IL-6, and IL-8. Tulobuterol treatment produces a small but significant reduction in the amount of p50, p65, and c-Rel of NF-κB induced by RV14 infection[1].

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

RT-PCR[1]

Cell Line: Human tracheal epithelial cells infected with RV14
Concentration: 0.1 μM
Incubation Time: 24 hours or 72 hours
Result: Decreased the RV14 RNA levels at 1 day and at 3 days after infection. The concentrations of sICAM-1 in the supernatants of the cells were significantly lower. Reduced the number of acidic endosomes with green fluorescence in the cells and the fluorescence intensity of acidic endosomes in the cells. Also reduced the RV14 infection-induced secretion of IL-1β, IL-6, and IL-8. And produced a small but significant reduction in the amount of p50, p65, and c-Rel of NF-κB induced by RV14 infection.
体内研究
(In Vivo)

In vivo effect of Tulobuterol is examined the on the contractility of diaphragm muscles prepared from mice (BALBs/c mice; 21.7 ± 0.2 g) treated with Endotoxin. Contractile parameters of force-frequency curves and twitch kinetics using untreated or treated diaphragm muscles at 0 (E0) and 4 (E4) hours after E. coli endotoxin (20 mg/kg) administration are measured. E0 and E4 diaphragm muscles are analyzed at 0, 12, and 24 h after transdermal Tulobuterol treatment. The force-frequency curves of E0 and E4 diaphragm muscles at three time points are not significantly changed each other, indicating that Tulobuterol patch restores the muscle contractility. Thus, diaphragm muscle contractility is maintained during 4 h of endotoxin administration with Tulobuterol patch for over 24 h[3].

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.46 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

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.
