产品描述 | Dexamethasone is a glucocorticoid receptor agonist and IL receptor modulator with anti-inflammatory, immunosuppressive, and apoptosis-inducing activities. It inhibits the production of inflammatory miRNA-155 exosomes in macrophages, significantly reduces inflammatory cytokine expression in neutrophils and monocytes, suppresses LPS-induced macrophage inflammation, and induces autophagy. It is commonly used to induce animal models of depression, muscle atrophy, and hypertension, and holds potential in COVID-19 research. |

体外活性 | 方法:人结直肠癌细胞 LoVo 和 HCT116 用 Dexamethasone (10-300 µM) 处理 72 h,使用 MTT 方法检测细胞生长抑制情况。 |
体内活性 | 方法:为研究抗炎作用,将 Dexamethasone (1-10 mg/kg) 单次腹腔注射给 LPS 诱导的炎症 C57Bl/6JBom 小鼠。 |
动物实验 | NAC was administered at three different doses (10, 100 and 500 mg/kg body weight). At the highest concentration, the acidic pH of the NAC solution was adjusted by adding NaOH. Dexamethasone was administered as a single injection of 1 or 10 mg/kg. Both drugs were dissolved in saline and 400 μl were injected intraperitoneally, either 1 h before or 1 h after LPS exposure. In one experiment, NAC (100 and 500 mg/kg) was injected successively every 4·5 h, starting 1 h before challenge (five injections in total). A control group of LPS-exposed animals were injected intraperitoneally with solvent alone (saline). Intratracheal administration was 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.) [4]. |
