Antiobesity and antidiabetic actions of the alpha-glucosidase inhibitor AO-128 were examined using genetically obese-diabetic rats, Wistar fatty. Ten-week-old, male fatty rats were kept on CE-2 diet containing 10 or 25 ppm of AO-128 for 4 weeks. The average drug intake was calculated to be 0.74 or 1.78 mg/kg/day from the average food intake, respectively. The intestinal maltase and sucrase activities were decreased by AO-128 in a dose-related fashion. Food intake of fatty rats treated with AO-128 was decreased throughout the experiment. This decrease in food intake could hardly be explained only by diarrhea which occurred for the first 5 days of the administration of AO-128. AO-128 normalized hyperglycemia and markedly reduced hypertriglyceridemia and hyperinsulinemia in fatty rats. In addition, AO-128 decreased body weight gain, food efficiency, epididymal adipose tissue weight, carcass weight, and body fat deposition. These findings indicate that AO-128 may be useful for treating human obesity and diabetes.

L-Arabinose is a natural, poorly absorbed pentose that selectively inhibits intestinal sucrase activity. To investigate the effects of L-arabinose feeding on lipogenesis due to its inhibition of sucrase, rats were fed 0-30 g sucrose/100 g diets containing 0-1 g L-arabinose/100 g for 10 d. Lipogenic enzyme activities and triacylglycerol concentrations in the liver were significantly increased by dietary sucrose, and arabinose significantly prevented these increases. Arabinose feeding reduced the weights of epididymal adipose tissue. Moreover, plasma insulin and triacylglycerol concentrations were significantly reduced by dietary L-arabinose. These findings suggest that L-arabinose inhibits intestinal sucrase activity, thereby reducing sucrose utilization, and consequently decreasing lipogenesis.
