Uses
Xanthohumol D, isolated from hops, is an inhibitor of quinone reductase-2 (QR-2) with the IC50 value of 110 μM, and binds to the active site of QR-2. Xanthohumol D shows antiproliferative activity on human cancer cell lines in vitro[1][2].
Definition
ChEBI: Xanthohumol D is a member of the class of chalcones that is trans-chalcone substituted by hydroxy groups at positions 4, 2' and 4', a methoxy group at position 6' and a 2-hydroxy-3-methylbut-3-en-1-yl group at position 3'. It has been isolated as a racemate from Humulus lupulus and has been shown to exhibit inhibitory activity against NO production. It has a role as a metabolite and an EC 1.14.13.39 (nitric oxide synthase) inhibitor. It is a member of chalcones, a polyphenol, an aromatic ether and a secondary alcohol.
