生物活性

Dexamethasone phosphate (Dexamethasone 21-phosphate) disodium is an orally active Glucocorticoid receptor agonist[1].

IC50 & Target

Glucocorticoid receptor[1]

体外研究
(In Vitro)

Dexamethasone phosphate disodium 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 phosphate disodium 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 phosphate disodium (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 phosphate disodium (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]

体内研究
(In Vivo)

用 2×5 mg/kg 剂量的 Dexamethasone phosphate disodium 处理可有效抑制脂多糖 (LPS) 诱导的炎症。在我们的实验系统中,与暴露于 LPS 并单独注射溶剂 (盐水) 的动物相比,单剂量 Dexamethasone phosphate disodium 10 mg/kg (ip) 处理显著减少了粒细胞的募集以及氧自由基的自发产生。在吸入 LPS 前 1 小时和吸入后 1 小时给药时,效果具有统计学意义。BALF 中的粒细胞数量下降到与健康动物相当的水平 (给予水气溶胶)[3]。用 Dexamethasone phosphate disodium 处理的大鼠比对照大鼠消耗更少的食物并且体重更轻。尽管它们的食物摄入量相似,但经过处理的大鼠的体重也低于配对喂养的动物。注射 Dexamethasone phosphate disodium 五天导致肝脏质量 (+42%) 和肝脏与体重的比率 (+65%) 显著增加。处理 5 天后腓肠肌湿重下降 20%,但相对于体重 (g/100 g 体重) 仍未受影响,表明肌肉减重与体重减轻同步[4]

Animal Administration
[3][4]

Rats: 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. Control rats receive 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[4].

Mice: 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 anaesthetized with 15 mg/kg Rapinovet (i.v.)[3].

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.
