Phytochemistry and Biological Activities

Anthocyanins are a group of bioactive compounds present in plant foods. Although they have consistently shown an anti-inflammatory effect both in vitro and in vivo, their mechanisms of action are not fully understood and have only recently begun to be elucidated. The aim of this review is to highlight the anti-inflammatory activity of anthocyanins, including their effect on the expression of several genes involved in inflammation. The available evidence suggests that their anti-inflammatory action can be attributed primarily to their antioxidant properties, which result in downregulation of the redox-sensitive nuclear factor-κB signaling pathway. Other pathways at least partly involved in the inflammatory response, particularly the mitogen-activated protein kinase pathways, also appear to play a role. A discussion is presented on the most effective dose of anthocyanins, the differential contribution of specific compounds, the comparative effects of anthocyanins versus other anti-inflammatory phenolic compounds, and the extent to which the observed biological activities are exerted by anthocyanins themselves or their metabolites.
