Xanthohumol is one of the principal flavonoids isolated from hops, the inhibitor of diacylglycerol acetyltransferase (DGAT), COX-1 and COX-2, and shows anti-cancer and anti-angiogenic activities. Xanthohumol also has antiviral activity against bovine viral diarrhea virus (BVDV), rhinovirus, HSV-1, HSV-2 and cytomegalovirus (CMV).

Xanthohumol significantly attenuates ADP-induced blood platelet aggregation, and significantly reduces the expression of fibrinogen receptor (activated form of GPIIbIIIa) on platelets surface.Xanthohumol (5-50 nM) reduces the frequency of spontaneously occurring Ca sparks and Ca waves in control myocytes and in cells subjected to Ca overload caused by: (1) exposure to low K solutions, (2) periods of high frequency electrical stimulation, (3) exposures to isoproterenol or (4) caffeine. Xanthohumol (50-100 nM) reduces the rate of relaxation of electrically- or caffeine-triggered Ca transients, without suppressing ICa, but this effect is small and reversed by isoproterenol at physiological temperatures. Xanthohumol also suppresses the Ca content of the SR, and its rate of recirculation. Treatment of endothelial cells with Xanthohumol leads to increased AMPK ph
