Vancomycin is a glycopeptide antibiotic widely used to treat infections caused by methicillin-resistant Staphylococcus aureus. However, nephrotoxicity is a major adverse side effect, and the development of effective nephroprotective agents remains a priority in antimicrobial chemotherapy. In this study, we investigated the cell protective effects of the flavonol glycoside rutin against vancomycin-induced toxicity. Vancomycin added to porcine renal tubular LLC-PK1 cells caused an increase of production of intracellular reactive oxygen species and subsequent apoptotic cell death. Pretreatment of LLC-PK1 cells with rutin at 5, 10, and 20 μM for 2 hr prior to 2-mM vancomycin exposure for 24 hr significantly decreased intracellular reactive oxygen species and increased superoxide dismutase and catalase activities. Rutin pretreatment also protected cells from vancomycin-induced caspase activation, mitochondrial membrane depolarization, and subsequent apoptosis. This study demonstrates a protective effect of rutin and suggests that rutin coadministration is an alternative therapy for treatment of vancomycin-induced nephrotoxicity.
