Comparative toxicokinetics of Trans-resveratrol and its major metabolites in Harlan Sprague Dawley rats and B6C3F1/N mice following oral and intravenous administration.

ABSTRACT: Trans-resveratrol (RES) is a naturally occurring stilbene found in numerous plants and foods. Due to its widespread human exposure and lack of toxicity and carcinogenicity data, RES was nominated to the National Toxicology Program for testing. To aid the toxicology studies, the dose, sex, and species differences in RES toxicokinetics was investigated in Harlan Sprague Dawley rats and B6C3F1/N mice following single intravenous (IV) (10 mg/kg) or oral gavage administration (312.5, 625, and 1250 mg/kg and 625, 1250, and 2500 mg/kg in rats and mice, respectively). Following IV and gavage administration, systemic exposure of RES based on AUC was trans-resveratrol-3-O-β-D-glucuronide (R3G)> > trans-resveratrol-3-sulfate (R3S) > RES in both species. Following gavage administration T_{max_predi}
