Chalconoids

Chalcone is the organic compound C6H5C(O)CH=CHC6H5. It is an α,β-unsaturated ketone. A variety of important biological compounds are known collectively as chalcones or chalconoids. They are widely known bioactive substances, fluorescent materials, and chemical intermediates.

Xanthohumol is a natural product found in the female inflorescences of Humulus lupulus, also known as hops. This compound is also found in beer and belongs to a class of compounds that contribute to the bitterness and flavor of hops. Xanthohumol is a prenylated chalconoid, biosynthesized by a type III polyketide synthase (PKS) and subsequent modifying enzymes.

Butein is a chalcone of the chalconoids. It can be found in Toxicodendron vernicifluum (or formerly Rhus verniciflua), Dahlia, Butea (Butea monosperma) and Coreopsis. It has antioxidative, aldose reductase and advanced glycation endproducts inhibitory effects. It is also a sirtuin-activating compound, a chemical compound having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. Buteins possess a high ability to inhibit aromatase process in the human body, for this reason, the use of these compounds in the treatment of breast cancer on the estrogen gr

Isoliquiritigenin is a chalcone found in the roots of several Glycyrrhiza species, such as liquorice, studied for its activity as a tyrosinase inhibitor, NMDA receptor antagonist, GABA modulator, and its potential antineoplastic and geroprotective effects.

Cardamomin (also known as cardamonin) is a chalconoid that has been isolated from several plants including Alpinia katsumadai and Alpinia conchigera. It has received growing attention from the scientific community due to the expectations toward its benefits to human health.
