| Cell experiment [1]: | |
|
Cell lines |
Human osteosarcoma cell lineMG-63 |
|
Preparation method |
The solubility of this compound in DMSO is >19.6mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months. |
|
Reacting condition |
100 nM; 0-36 h |
|
Applications |
In human osteoblast-like cell lineMG-63, Dexamethasone (Dex) exhibited dose-dependently upregulating RhoB protein expression. Dex treatment for above 2 days could significantly inhibit the growth of MG-63 cells in a dose dependent way. |
| Animal experiment [2]: | |
|
Animal models |
LPS-induced neuroinflammation mice |
|
Dosage form |
0.25 mg/kg; intravenous (IV) or intranasal (IN). |
|
Application |
In LPS-induced neuroinflammation mice, IN administration of DX significantly reduced the level of IL-6 in the brain extracts and reduced the percentage of GFAP+ brain cells one day after treatment. Compared with IV route, higher levels of DX are observed in the cerebrovasculature of mice after IN administration. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
