The effect of KCD-232, a new compound with a structure of 4-(4-chlorobenzyloxy)benzyl nicotinate, on fructose-induced hypertriglyceridemia and fatty liver was studied in rats refed experimental diets for 3 days after having been starved for 2 days. In younger or older rats refed 7% corn oil-containing diets, both the serum and livertriglyceride (TG) levels were higher in the fructose (F) group than in the glucose (G) group, and those of the F group were higher in the older rats than the younger rats. KCD-232effectively inhibited fructose-induced hypertriglyceridemia and fatty liver in both the younger and older rats. In older rats refed 7% corn oil diets, an increase in hepatic fatty acid (FA) synthesis and decreases in the activities of hepatic TG lipase (HTGL) and adipose tissue lipoprotein lipase (LPL) were found in the F group, while the serum free FA level and hepatic FA oxidative activity of the F group were equal to those of the G group. KCD-232 strongly inhibited the fructose-enhanced FA synthesis, slightly repressed the fructose-suppressed HTGLactivity and had no effect on LPL activity and FA oxidation. These results suggest that fructose-induced hypertriglyceridemia and fatty liver are due to an enhanced hepatic FA synthesis and decreased hydrolytic activities required for TG clearance from the circulation system and that KCD-232 prevents them by inhibiting enhanced FA synthesis.
