OBJECTIVE
To investigate the preventative activity of benzyl isothiocyante and S-carvone against high-fat diet-induced obesity and metabolic complications.
METHODS
Ten-week-old C57BL/6 male mice were fed a high-fat diet and injected intraperitoneally twice per week with benzyl isothiocyante, S-carvone, or vehicle for 8 weeks. The body weight, food intake, and body composition were monitored, and glucose tolerance and insulin tolerance tests were performed at the end of the experiment. Serum and tissue samples were studied using serum biochemistry, histological, and gene expression analysis to define the effects of benzyl isothiocyante and S-carvone treatments on lipid and glucose metabolism and inflammatory responses.
RESULTS
Benzyl isothiocyante and S-carvone blocked high-fat diet-induced weight gain, fat accumulation in the liver, and insulin resistance. The beneficial effects were found to be associated with an improvement of expression of macrophage marker genes in white adipose tissue, including F4/80, Cd11b, Cd11c, Cd206, and Tnf-α, and reduced expression of genes (Pparγ2, Scd1, Cd36) responsible for lipid synthesis and transport in the liver.
CONCLUSIONS
Benzyl isothiocyante and S-carvone block high-fat diet-induced obesity and metabolism disorders and can be considered for management of the obesity epidemic that affects approximately 36% of adults and 17% of children in the USA.
