Resveratrol is a phytoalexin produced naturally by several plants with anti-cancer, anti-inflammatory, blood-sugar-lowering and other beneficial cardiovascular effects.
Cell lines
primary neuronal cultures; the neuroblastoma SH-SY5Y cell line
Preparation method
The solubility of this compound in DMSO is >9.7 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months.
Reacting condition
0.1, 1, and 10 μM; 50 μM
Applications
In primary neuronal cultures, resveratrol (0.1, 1, and 10 μM) inhibited OGD/reperfusion-induced apoptosis and inhibited the overexpression of caspase-3 and caspase-12 mRNA in a concentration-dependent way. In the neuroblastoma SH-SY5Y cell line, resveratrol (50 μM) inhibited excess dopamine-induced cell death by ameliorating intracellular oxidative stress and increasing the activity of prosurvival gene Bcl-2.
Animal models
rats subjected to myocardial ischemia
Dosage form
2.5, 5.0, 25 or 50 mg/kg; fed for 14 days by gavaging
Application
In rats subjected to myocardial ischemia, resveratrol (2.5, 5.0 mg/kg) exhibited cardioprotection by improved post-ischemic ventricular recovery and reduction of myocardial infarct size and cardiomyocyte apoptosis. However, 25 or 50 mg/kg dose of resveratrol inhibited cardiac function and increased myocardial infarct size and number of apoptotic cells.
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.
