|Description:||1. Xanthohumol and xanthohumol D are potent inducers of quinone reductase, suggests that they could be used as chemoprevention agents.|
|Targets:||IFN-γ | NO|
|Source:||The herbs of Humulus lupulus|
|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.|

|Fungal metabolites of xanthohumol with potent antiproliferative activity on human cancer cell lines in vitro.[Pubmed: 23434138]|
|Xanthohumol (1) and Xanthohumol D (2) were isolated from spent hops. Isoxanthohumol (3) was obtained from xanthohumol by isomerisation in alkaline solution. Six metabolites were obtained as a result of transformation of xanthohumol (1) by selected fungal cultures. Their structures were established on the basis of their spectral data. One of them: 2″-(2'''-hydroxyisopropyl)-dihydrofurano-[4″,5″:3',4']-4',2-dihydroxy-6'-methoxy-α,β-dihydrochalcone (6) has not been previously reported in the literature. The antioxidant properties of hops flavonoids and Xanthohumol Derivatives were investigated using the 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.|

|Screening method for the discovery of potential cancer chemoprevention agents based on mass spectrometric detection of alkylated Keap1.[Pubmed: 16194107]|
|Two of these electrophilic hops constituents were identified as xanthohumol and Xanthohumol D. In a subsequent cell-based assay, xanthohumol and Xanthohumol D were confirmed to be potent inducers of quinone reductase, and reaction with Keap1 was also confirmed. Therefore, this new mass spectrometric screening assay was demonstrated to facilitate the discovery of chemoprevention agents in complex natural product mixtures.|
