Xanthohumol lowers body weight and fasting plasma glucose in obese male Zucker fa/fa rats.

Obesity contributes to increased risk for several chronic diseases including cardiovascular disease and type 2 diabetes. Xanthohumol, a prenylated flavonoid from hops (Humulus lupulus), was tested for efficacy on biomarkers of metabolic syndrome in 4 week old Zucker fa/fa rats, a rodent model of obesity. Rats received daily oral doses of xanthohumol at 0, 1.

Xanthohumol and related prenylated flavonoids inhibit inflammatory cytokine production in LPS-activated THP-1 monocytes: structure-activity relationships and in silico binding to myeloid differentiation protein-2 (MD-2).

Xanthohumol (XN) is a prenylated chalcone-type flavonoid found in hops and beer. Our objective of this study was to determine the anti-inflammatory activities of XN, isoxanthohumol (IX), and 15 related prenylated chalcones and flavanones, as well as their structure-activity relationships. The anti-inflammatory activities of the flavonoids were measured by their ability to inhibit lipopolysaccharide (LPS)-induced cytokine production in human monocytic THP-1 cells.
