Abstract

Hesperidin methyl chalcone (HMC) is a safe flavonoid used to treat chronic venous diseases, but its effects and mechanisms on UVB irradiation-induced inflammation and oxidative stress have never been described in vivo. Thus, the purpose of this study was to evaluate the effects of systemic administration of HMC in skin oxidative stress and inflammation induced by UVB irradiation. To induce skin damage, hairless mice were exposed to an acute UVB irradiation dose of 4.14 J/cm(2), and the dorsal skin samples were collected to evaluate oxidative stress and inflammatory response. The intraperitoneal treatment with HMC at the dose of 300 mg/kg inhibited UVB irradiation-induced skin edema, neutrophil recruitment, and matrix metalloproteinase-9 activity. HMC also protected the skin from UVB irradiation-induced oxidative stress by maintaining ferric reducing antioxidant power (FRAP), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS) scavenging ability and antioxidant levels (reduced glutathione and catalase). Corroborating, HMC inhibited UVB irradiation-induced superoxide anion generation and gp91phox (NADPH oxidase subunit) mRNA expression. Furthermore, the antioxidant effect of HMC resulted in lower production of inflammatory mediators, including lipid hydroperoxides and a wide range of cytokines. Taken together, these results unveil a novel applicability of HMC in the treatment of UVB irradiation-induced skin inflammation and oxidative stress.
