Introduction and objectives:

oxidative stress is considered one of the main mechanisms of genotoxicity and carcinogenicity of heavy metals. In contrast, resveratrol has antioxidant properties and is one of the most studied polyphenols due to its wide variety of beneficial health effects. However, there are no systematic reviews of the scientific literature in which the effects of resveratrol on oxidative stress induced by heavy metals are analyzed.

Methods:

in this review, articles were searched using the PubMed® and ScienceDirect® databases (1996-2018). After applying various filters, eleven in vivo and in vitro researches were considered, in which the effects of resveratrol on oxidative stress as induced by arsenic (As), cadmium (Cd), copper (Cu), chromium (Cr) and iron (Fe) were studied.

Results:

this review presents an analysis of the chemical effects of resveratrol on the oxidative stress associated with exposure to metal compounds. The interaction of resveratrol with the production of reactive oxygen species (ERO), the endogenous antioxidant system, and the effects on DNA damage are discussed. From these studies a diagram that shows the proposed interactions for resveratrol, heavy metals As, Cd, Cu, Cr and Fe, and oxidative stress is generated.

Conclusions:

the studies analyzed show that resveratrol is able to modulate the oxidative stress generated by different heavy metal compounds such as As, Cd, Cu, Cr and Fe.
