| Description | 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. |

| In vitro | METHODS: Human colorectal cancer cells LoVo and HCT116 were treated with Dexamethasone (10-300 µM) for 72 h. Cell growth inhibition was detected by MTT. RESULTS: Dexamethasone dose-dependently inhibited the growth of LoVo and HCT116 cells, and the inhibition rates of 300 µM Dexamethasone were 52.6% and 58.8%, respectively. [1] METHODS: Acute lymphoblastic leukemia cells RS4;11 were treated with Dexamethasone (100 nM) for 24-36 h. Cell morphology was examined using electron microscopy. RESULTS: In cells treated with Dexamethasone for 24 h, vesicles were surrounded by double membranes, which are characteristic of autophagosomes, and contained membrane structures and/or part of the endoplasmic reticulum or a large amount of cytoplasm. In addition to the appearance of autophagosomes, the nucleus and cell morphology were initially intact, suggesting that autophagosome formation preceded cell death. Dexamethasone induces autophagy. [2] METHODS: Activated mouse and human T cells were treated with Dexamethasone (0.001-10 μM) for 48 h, and PD-1 expression was detected by Flow Cytometry. RESULTS: Dexamethasone enhanced the expression of PD-1 in mouse and human activated T cells. [3] |
| In vivo | METHODS: To investigate the anti-inflammatory effects, Dexamethasone (1-10 mg/kg) was administered as a single intraperitoneal injection to LPS-induced inflammation in C57Bl/6JBom mice. RESULTS: 10 mg/kg Dexamethasone significantly reduced neutrophils in bronchoalveolar lavage fluid.Dexamethasone treatment significantly down-regulated the levels of TNF-α, IL-1α, IL-1β, IL-6, IL-12p40 and MIP-1α mRNA. Dexamethasone exerts anti-inflammatory and antioxidant functions in acute airway inflammation. [4] METHODS: To detect anti-tumor activity in vivo, Dexamethasone (1 mg/kg) was intraperitoneally injected into SCID mice harboring the human myeloma tumor OPM2 five days per week for three weeks. RESULTS: Dexamethasone treatment significantly inhibited the growth of OPM2 tumors, indicating antitumor activity in vivo. [5] |

| Animal Research | 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]. |

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 µL Tween 80 and mix well until fully clarified.
3) Add 450 µL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
