|Description:||1. Echinatin disturb the mitochondrial energy transfer reactions and membrane permeability, at a low concentration cause deterioration of respiratory control and oxidative phosphorylation of isolated rat liver mitochondria, inhibits DNP-ATPase activity while stimulating range latent ATPase activity. |
2. Echinatin has significant antioxidant activities, it shows strong scavenging activity toward the ABTS + radical, it also dose-dependently inhibits LPS induced reactive oxygen species (ROS) production in RAW 264.7 cells and inhibits the production of nitric oxide (NO), interleukin-6 (IL-6) and prostaglandin E2 (PGE2) in LPS-induced macrophage cells.
|Targets:||ATPase | ROS | NO | PGE | IL Receptor|
|Source:||The root of Glycyrrhiza glabra L.|
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

|The effects of echinatin and its related compounds on the mitochondrial energy transfer reaction.[Pubmed: 6221118]|
|To investigate the mechanism by which various biological action of licorice root are brought about, the effects of Echinatin as a small constituent of Glycyrrhiza echinata and several related compounds on mitochondrial energy transfer reactions were examined. The results obtained were as follows: 1) Echinatin, 4'-hydroxychalcone, chalcone and 3,4'-dihydroxychalcone at a low concentration cause deterioration of respiratory control and oxidative phosphorylation of isolated rat liver mitochondria. 2) Chalcone and 4'-hydroxychalcone stimulate both latent and DNP-ATPase activity of mitochondria. Echinatin inhibits DNP-ATPase activity while stimulating range latent ATPase activity in the low concentration. 3) Chalcone and 4'-hydroxychalcone induce a rapid potassium release from mitochondrial vesicles, while Echinatin and 3,4'-dihydroxychalcone have lesser effect than the former two substances. From these results, it can be concluded that Echinatin and several related compounds disturb the mitochondrial energy transfer reactions and membrane permeability.|

|Antioxidant and anti-inflammatory activities of six flavonoids separated from licorice.[Pubmed: 23790887]|
|In this work, six flavonoids, 5-(1,1-dimethylallyl)-3,4,4'-trihydroxy-2-methoxychalcone (1), licochalcone B (2), licochalcone A (3), Echinatin (4), glycycoumarin (5) and glyurallin B (6), were isolated from the extracts of licorice (Glycyrrhiza inflata and Glycyrrhiza uralensis). Their structures were elucidated using various spectroscopic methods. To our knowledge, compound 1 was isolated from natural plants for the first time. All the isolates were tested by antioxidant and anti-inflammatory assays. Compounds 2, 4 and 5 showed strong scavenging activity toward the ABTS(+) radical, and compounds 1, 2, 3, 5 and 6 exhibited potent inhibition of lipid peroxidation in rat liver microsomes compared with the reference controls. Compounds 1-4 dose-dependently inhibited LPS induced reactive oxygen species (ROS) production in RAW 264.7 cells. Furthermore, compounds 1-5 were demonstrated to inhibit the production of nitric oxide (NO), interleukin-6 (IL-6) and prostaglandin E2 (PGE2) in LPS-induced macrophage cells.|

|Determination of antioxidant activity in licorice vitro metabolites by DPPH spiking coupled with HPLC-Q-TOF MS/MS[Reference: WebLink]|
|Objective: To investigate the antioxidant activity of liver microsomal metabolites from six flavonoids in licorice by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) spiking coupled with HPLC-Q-TOF MS/MS. Methods: The six flavonoids were incubated with rat liver microsomes and the resultant metabolites were identified by HPLC-Q-TOF MS/MS. The antioxidant activity of the metabolites was calculated by comparing the peak area changes before and after incubation with DPPH. Results: The peak area of the metabolites significantly decreased or even disappeared after incubation with DPPH. Besides the metabolites Lico A-M1 and Lico A-M2 of licochalcone A, more than 90% of other metabolites of flavonoids were oxidized. Conclusion: Liver microsomal metabolites of Echinatin, licochalcone B, licochalcone A, 5-(1, 1-dimethylally)-3, 4, 4'-trihydroxy-2-methoxychalcone, glycycourmarin and glyurallin B still have significant antioxidant activities.|
