A. Cal27 cells transfected with GFP-LC3 plasmid were treated with different concentration of DHM for 24 h. The formation of GFP-LC3 puncta were examined using immunofluorescence and quantified. Scale bar 50 μm.
Oncotarget, 2016.. Dihydromyricetin purchased from Selleck.
ADH and ALDH expressions in 40% ethanol loaded mice for three hours. Group 1, 500 lM taraxerone; Group 2, 1 mM taraxerone; Group 3, 3 mM DHM (positive control); Group 4, DMSO (control); Group 5, saline. Taraxerone and DHM were dissolved in DMSO, and all treated samples (ethanol, taraxerone, DHM, DMSO, and saline) were administered orally (5 mL/kg body weight). The same letters denote significant differences at p < 0.05, and the error bar represents standard deviation.

|Description||Dihydromyricetin (Ampelopsin, Ampeloptin) is a natural antioxidant flavonoid from Ampelopsis grossedentata.|
Dihydromyricetin shows antioxidant activity as an effective scavenger of 1,1-diphenyl-2-picrylhydrazyl radical (DPPH). It also inhibits the increase of lipid peroxidation (LPO) values in linolei acid system catalyzed by FeSO4-edetic acid.  DHM (1 μM) as a novel anti-alcohol intoxication medication antagonizes both acute EtOH-induced potentiation of GABA(A)Rs and EtOH exposure/withdrawal-induced GABA(A)R plasticity and increases in GABA(A)R alpha4 subunit expression in hippocampus and cultured neurons. 
|In vivo||Dihydromyricetin (1 mg/kg, i.p.) counteracts acute alcohol (EtOH) intoxication, and also withdrawals signs in rats including tolerance, increased anxiety, and seizure susceptibity.  LD50: Mice 1.41g/kg (i.p.) |
|In vitro||DMSO||64 mg/mL (199.84 mM)|
|Ethanol||64 mg/mL (199.84 mM)|
|Water||slightly soluble or insoluble|
|In vivo||Add solvents individually and in order:
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
