|Biological Activity or Inhibitors:||1. Licoisoflavone A is a potential MRP inhibitor.
2. Licoisoflavone A and licoisoflavone B show inhibitory effects on copper-induced protein oxidative modification of mice brain homogenate in vitro.
|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.

|After receiving:||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.|

|Monitoring of MRP-like activity in human erythrocytes: inhibitory effect of isoflavones.[Pubmed: 11783953]|
|A method to fluorometrically monitor efflux of 2',7'-bis-(carboxypropyl)-5(6)-carboxyfluorescein (BCPCF) from human erythrocytes was developed. Genistein, daidzein, sophoraisoflavone A, and Licoisoflavone A induced 50% inhibition (IC(50)) of BCPCF efflux at 15-70 microM. The IC(50) value of the most efficient isoflavone, Licoisoflavone A (15-25 microM), was comparable to that of indomethacin (approximately 10 microM) and markedly lower than for probenecid (100-200 microM), both known MRP1 inhibitors. Our results indicate that the human erythrocyte is a useful cell model in screening potential MRP inhibitors, that BCPCF is a good substrate for MRP, and that some isoflavones at low concentrations inhibit MRP-mediated efflux.|

|Inhibitory effects of licoisoflavones A and B and sophoraisoflavone A of Sophra mooracroftiana Beth ex Baker on copper-ion-induced protein oxidative modification of mice brain homogenate, in vitro.[Pubmed: 11554397]|
|We present the results of an in vitro investigation of the inhibitory effects of Licoisoflavone A and licoisoflavone B and sophoraisoflavone A isolated from Sophra mooracroftiana BETH ex BAKER on copper-induced protein oxidative modification of mice brain homogenate in vitro. Although inhibitory effect of sophoraisoflavone A was stronger than those of Licoisoflavone A and licoisoflavone B, genistein as a related isoflavone, and mannitol as a hydroxy radical scavenger, inhibitory effects of Licoisoflavone A and licoisoflavone B were weaker than those of genistein and mannitol. These results demonstrated that the difference of inhibitory effects are dependent on the relation between chemical structures of these isoflavones, such as hydroxy group or benzopyran, and oxidative stress.|
