Flavonoid compounds from the red marine alga Alsidium corallinum protect against potassium bromate‐induced nephrotoxicity in adult mice
Potassium bromate (KBrO 3 ), an environmental pollutant, is a well‐known human carcinogen and a potent nephrotoxic agent. Currently, natural products have built a well‐recognized role in the management of many diseases induced by pollutants. As potent natural sources of bioactive compounds, marine algae have been demonstrated to be rich in novel secondary metabolites with a broad range of biological functions. In this study, adults male mice were orally treated for 15 days with KBrO 3 (0.5 g/L) associated or not with extract of Alsidium corallinum , a red Mediterranean alga. In vitro study demonstrated that algal extract has antioxidant efficacy attributable to the presence of flavonoids and polyphenols. Among these, Liquid chromatography–mass spectrometry analysis showed A. corallinum is rich in kaempferol, apigenin, catechin, and quercetin flavonoids. In vivo study showed that supplementation with the alga significantly prevented KBrO 3 ‐induced nephrotoxicity as indicated by plasma biomarkers (urea, uric acid, and creatinin levels) and oxidative stress related parameters (malondialdehyde, superoxide dismutase, catalase, glutathione peroxidase, reduced glutathione, vitamin C, hydrogen peroxide, protein oxidation products) in kidney tissue. The corrective effect of A. corallinum on KBrO 3 ‐induced kidney injury was also supported by molecular and histopathological observations. In conclusion, it was established that the red alga, thanks to its bioactive compounds, effectively counteracts toxic effects of KBrO 3 and could be a useful coadjuvant agent for treatment of this pollutant poisonings. © 2016 Wiley Periodicals, Inc.
