摘要

Gallic acid is an organic acid known for its antioxidant and anticancer properties. The present study is focused on evaluating the role of gallic acid in providing better therapeutic outcomes against arsenic-induced toxicity. Animals pre-exposed to arsenic were treated with monoisoamyl meso-2,3-dimercaptosuccinic acid (MiADMSA), a new chelating drug, alone and in combination with gallic acid, consecutively for 10 days. The study suggests that (1) gallic acid in presence of MiADMSA is only moderately beneficial against arsenic, (2) monotherapy with gallic acid is more effective than in combination with MiADMSA after arsenic exposure in reducing oxidative injury, and (3) MiADMSA monotherapy as reported previously provides significant therapeutic efficacy against arsenic. Thus, based on the present results, we conclude that gallic acid is effective against arsenic-induced oxidative stress but provides limited additional beneficial effects when administered in combination with MiADMSA. We still recommend that lower doses of gallic acid be evaluated both individually and in combination with MiADMSA, as it might not exhibit the shortcomings we observed with higher doses in this study.
