    生物活性

    Dexamethasone (Hexadecadrol) is a glucocorticoid receptor agonist, apoptosis inducer, and common disease inducer in experimental animals, constructing models of muscle atrophy, hypertension, and depression. Dexamethasone can inhibit the production of inflammatory miRNA-155 exosomes in macrophages and significantly reduce the expression of inflammatory factors in neutrophils and monocytes. Dexamethasone also has potential for use in COVID-19 research[1][2][3][4].

    IC50 & Target

    Glucocorticoid receptor[1]
    体外研究
    (In Vitro)

    Dexamethasone (Hexadecadrol) 调节多种转录因子，包括激活蛋白-1、核因子-AT 和核因子-kB，从而激活和抑制参与炎症反应的关键基因[1]。
    Dexamethasone 有效抑制 A549 细胞释放粒细胞-巨噬细胞集落刺激因子 (GM-CSF)，EC50 为 2.2 nM。Dexamethasone (EC50=36 nM) 诱导 β2 受体的转录被发现与糖皮质激素受体 (GR) DNA 结合相关，发生率高 10-100 倍浓度高于抑制 GM-CSF 释放。Dexamethasone (IC50=0.5 nM) 抑制 3×κB (NF-κB、IκBα 和 I-κBβ)，这与抑制 GM-CSF 释放有关[2]。

    Animal Administration
    [3][4]

    Mice[3]
    Female C57Bl/6JBom mice (age 10-12 weeks) are used in all experiments. Dexamethasone is administered as a single injection of 1 or 10 mg/kg. Dexamethasone is dissolved in saline and 400 μL are injected intraperitoneally, either 1 h before or 1 h after LPS exposure. In one experiment, N-acetylcysteine (NAC) (100 and 500 mg/kg) is injected successively every 4•5 h, starting 1 h before challenge (five injections in total). A control group of LPS-exposed animals are injected intraperitoneally with solvent alone (saline). Intratracheal administration is performed by instillation of 100 μL NAC (50, 100 or 500 mg/kg) or Dexamethasone (10 mg/kg) into the lungs of mice.
    Rats[4]
    Male Sprague-Dawley rats are used.Dexamethasone-treated rats are injected intraperitoneally once daily with Dexamethasone (1.5 mg/kg body weight) for 5 days and are allowed to feed ad libitum. The Dexamethasone dose (1.5 mg/kg/day) and the duration of treatment (5 days) are specifically chosen as this treatment induced a reproducible and marked catabolic state. Control rats received no treatment and are fed ad libitum. In order to take into account the decrease in food intake induced by Dexamethasone treatment, a third group of pair-fed rats are used. These rats are provided with the same amount of food as Dexamethasone-injected rats and are treated with a daily isovolumic intraperitoneal injection of NaCl (0.9%) for 5 days. After the final injection of Dexamethasone or NaCl, the animals are fasted overnight prior to being killed by decapitation.

    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.
