Isoxanthohumol is a prenylflavonoid, and it is a phytoestrogen. It is abbreviated as IX or IXN.

8-Prenylnaringenin can be produced from isoxanthohumol by flora in the human intestine,[1] and by fungi in cell cultures.[2]

This prenylflavonoid is found in hops and beer. It has limited estrogenic activity. At the concentration found in beer, it is unlikely to have an estrogenic effect in breast tissue.[3]

Derivatives of isoxanthohumol are: 7,4′-Di-O-methylisoxanthohumol; 7-O-methylisoxanthohumol; 7-O-n-pentylisoxanthohumol; 7,4′-di-O-n-pentyl-8-isoxanthohumol; 7,4′-Di-O-allylisoxanthohumol; 7,4′-Di-O-acetylisoxanthohumol; and 7,4′-Di-O-palmitoylisoxanthohumol.[4]
