Biosynthetic14C-labelling of xanthohumol in hop cones

Molecular Nutrition & Food Research, 2005
Xanthohumol (Xn) has well-established chemopreventive potential in vitro. In order to carry out in vivo bioavailability and tissue distribution studies,( 14)C-labelled Xn was produced by biolabelling. Supplying hop sprouts with 5 mCi [U-(14)C]glucose led to incorporation of (14)C into Xn. Delivering the radioactive precursor at once resulted in Xn with

Roasting of malt and xanthohumol enrichment in beer

European Food Research and Technology, 2013
The use of commercial roasted malts increases the content of the hop polyphenol xanthohumol (XN) in beer. This carrier effect is caused by high molecular melanoidins from roasted malt. Three roasting trials with different malts were performed in order to study the development of XN enrichment of wort and beer in laboratory and brewing trials. Different

Structural and electronic properties of xanthohumol metabolite

Journal of Molecular Structure: THEOCHEM, 2002
The structural and electronic properties of xanthohumol metabolite (M2) have been investigated theoretically by performing semi-empirical molecular orbital theory at the level of MNDO/3 calculations. The optimized structure and the electronic properties of the isolated molecule are obtained.

Acid–Base Properties of Xanthohumol: A Computational and Experimental Investigation

Journal of Natural Products, 2017
UV-vis spectrophotometry has been applied to determine acid dissociation constants of the prenylated chalcone xanthohumol. The pKa values were compared with those derived from pH-metric titrations. The order of the deprotonation site in the xanthohumol molecule was estimated by quantum mechanical calculations as 2'-OH, 4'-OH, and 4-OH. Furthermore, the

Xanthohumol inflammatory factor production and angiogenesis are inhibited by xanthohumol in breast cancer xenografts.

2008
Xanthohumol (XN), a natural polyphenol present in beer, is known to exert anti-cancer effects. However, its precise mechanisms are not yet clearly defined. The aim of this study was to investigate the effect of oral administration of XN in breast cancer xenografts in nude mice. Proliferation and apoptosis were first examined in MCF7 cell cultures after
