Total Synthesis of Xanthohumol

Journal of Natural Products, 2007
The total synthesis of xanthohumol (1) was accomplished in 10% overall yield from phloracetophenone after six steps. Insertion of a prenyl group onto the aryl ring was achieved by a para-Claisen rearrangement after using a Mitsunobu reaction to establish the key prenyl ether precursor.

Photochemical transformations of xanthohumol

Tetrahedron Letters, 2013
Abstract A photoinduced procedure for the addition of simple alcohols to xanthohumol, the major prenylated flavonoid of hop plants, has been developed. The reaction is regioselective, simple, and occurs in one pot to afford two new β adducts of xanthohumol.

Xanthohumol metabolites in faeces of rats

Phytochemistry, 2004
Xanthohumol (1), isolated from hop, was fed to rats in a dose of 1000 mg kg(-1) body weight. The faeces of the animals were collected after 24 and 48 h and analysed for metabolites of 1. Approximately 89% of the recovered flavonoid-compounds consisted of unchanged 1.

Zur Konstitution des Xanthohumols

Chemische Berichte, 1960
AbstractEs wird gezeigt, daß der aus Xanthohumol durch Alkali‐Abbau entstehende 2‐[γ.γ‐Dimethyl‐allyl]‐phloroglucin‐x‐methyläther mit dem 1‐Methyläther identisch sein dürfte. Die Synthese des Xanthohumol‐dimethyläthers (Kondensation von 3‐[γ.γ‐Dimethyl‐allyl]‐phloracetophenon‐4.6‐dimethyläther mit Anisaldehyd) steht in Einklang mit der Konstitution des

Xanthohumol, a New Natural Chalkone

Bulletin des Sociétés Chimiques Belges, 1957
AbstractXanthohumol is a yellow leaf pigment, present in all hop varieties. It is a chalkone and isomerizes into a flavanone on alkaline treatment. Xanthohumol has the molecular formula C21H22O3 contains three active hydrogen atoms, one methoxylgroup, one carbonylgroup and two double bonds. Alkaline hydrolysis of xanthohumol yields p.

Pitfalls in cell culture work with xanthohumol.

Die Pharmazie, 2012
Xanthohumol, the most abundant prenylated chalcone in hop (Humulus lupulus L.) cones, is well known to exert several promising pharmacological activities in vitro and in vivo. Among these, the chemopreventive, anti-inflammatory and anti-cancer effects are probably the most interesting.
