Isoxanthohumol is a bioactive prenylflavonoid primarily derived from hops (Humulus lupulus) and beer. This potent compound exhibits significant antiproliferative effects against multiple human cancer cell lines and inhibits metastatic tumor development in vivo. It also demonstrates broad-spectrum antiviral activity against herpes viruses (HSV1/HSV2) and bovine viral diarrhea virus (BVDV), making it a valuable candidate for pharmaceutical and nutraceutical research.
