Biological effects of xanthohumol. Xanthohumol (XN) has been shown to have wide spectrum of biological effects, by which it may also affect different pathophysiological mechanisms involved in the development and progression of chronic liver disease. Studies have shown that XN acts anti-angiogenic (Albini et al., 2006; Shamoto et al., 2013), anti-carcinogenic (Dorn et al., 2010a,b,c; Araujo et al., 2011), chemopreventive (Miranda et al., 2000c; Gerhauser et al., 2002; Dorn et al., 2010a), anti-microbial (Gerhauser and Frank, 2005; Rozalski et al., 2013; Kramer et al., 2015), anti-viral (Buckwold et al., 2004; Zhang et al., 2009, 2010; Lou et al., 2014), anti-inflammatoric (Dorn et al., 2010a, 2013; Jongthawin et al., 2012), as a ROS scavenger (Gerhauser et al., 2002), anti-diabetic (Legette et al., 2013), and anti-oxidative (Gerhauser et al., 2002). In regard to liver fibrogenesis, it was shown that XN has anti-fibrogenic potential (Dorn et al., 2010a, 2013; Yang et al., 2013) and inhibits HSC activation and proliferation (Dorn et al., 2010a). Moreover, XN improves the metabolic syndrome (Legette et al., 2013).
