General tips For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months.
We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months.
Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it.
About Packaging 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial.
2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial.
3. Try to avoid loss or contamination during the experiment.
Shipping Condition Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request.

Aldose reductase inhibitory compounds from Glycyrrhiza uralensis.[Pubmed:20460778]

Biol Pharm Bull. 2010;33(5):917-21.

We evaluated the inhibitory effects of components from the root of Glycyrrhiza uralensis (G. uralensis) on aldose reductase (AR) and sorbitol formation in rat lenses with high levels of glucose as part of our ongoing search of natural sources for therapeutic and preventive agents for diabetic complications. In order to identify the bioactive components of G. uralensis, 5 prenylated flavonoids (Semilicoisoflavone B, 7-O-methylluteone, dehydroglyasperin C, dehydroglyasperin D, and isoangustone A), three flavonoids (liquiritigenin, isoliquiritigenin, and licochalcone A), and two triterpenoids (glycyrrhizin and glycyrrhetinic acid) were isolated; their chemical structures were then elucidated on the basis of spectroscopic evidence and comparison with published data. The anti-diabetic complication activities of 10 G. uralensis-derived components were investigated via inhibitory assays using rat lens AR (rAR) and human recombinant AR (rhAR). From the 10 isolated compounds, Semilicoisoflavone B showed the most potent inhibition, with the IC(50) values of rAR and rhAR at 1.8 and 10.6microM, respectively. In the kinetic analyses using Lineweaver.Burk plots of 1/velocity and 1/concentration of substrate, Semilicoisoflavone B showed noncompetitive inhibition against rhAR. The results clearly indicated that the presence of a gamma,gamma-dimethylchromene ring is partly responsible for the AR inhibitory activity of isoprenoid-type flavonoids. Further, Semilicoisoflavone B inhibited sorbitol formation of rat lens incubated with a high concentration of glucose, indicating that this compound may be effective for preventing osmotic stress in hyperglycemia.

Description

Semilicoisoflavone B, an isoflavone, mainly derived from Glycyrrhiza uralensis Fisch.. Semilicoisoflavone B reduces amyloid β (Aβ) secretion by inhibiting β-secretase-1 (BACE1) expression and activity. Semilicoisoflavone B decreases BACE1 expression mainly through increasing PPARγ expression and inhibiting STAT3 phosphorylation.
