Abstract
When isolated rat adipocytes were incubated with increasing concentrations of levamisole (0.5–5 mM), basal glucose oxidation decreased by almost 50% and insulin-stimulated glucose oxidation decreased by 90%. The decrease in glucose oxidation correlated with an inhibition of glucose transport, since levamisole at 5.0 mM decreased basal 3-O-methylglucose transport by 60% and insulin-stimulated transport by 80%. Diamide-stimulated glucose transport was also inhibited approximately 80% by 5.0 mM levamisole. Levamisole at concentrations up to 5.0 mM had no effect on phosphofructokinase activity. The present results suggest that levamisole inhibits glucose utilization by inhibiting glucose transport in a concentration-dependent manner.Key words: insulin, levamisole, glucose transport, adipocytes.
