In a previous paper we have reported that, unlike alloxan, the hyperglycemic action of 1-(p-chlorophenylsulfonyl)-2-imidazolidinone (CPSI) might be induced by its inhibitory effect on the releasing process of insulin from pancreatic β cells. In this paper, influences of CPSI on carbohydrate and lipid metabolism have been investigated comparatively with that of chlorpropamide (P-607). The results obtained were summarized as follows. 1) The muscular and liver glycogen levels in rats were both lowered by P-607 (100 mg/kg, p.o.), whereas CPSI (100 mg/kg, p.o.) increased the liver glycogen level and lowered the muscular glycogen level significantly. 2) The serum free fatty acids and triglycerides levels in the fasted rats were both lowered by P-607 (100 mg/kg, p.o.), whereas increased by CPSI (100 mg/kg, p.o.). These phenomenon were markedly manifested when a relatively large quantities of CPSI and P-607 (both 300 mg/kg, p.o.) were dosed to the fed rats. 3) The serum total cholesterol level in the fed rats were lowered by P-607 (300 mg/kg, p.o.), whereas increased by CPSI (300 mg/kg, p.o.). The results obtained seems to give a good explanation for the behavior of the peripheral blood insulin level toward to CPSI and P-607. They may support our suggestion strongly that CPSI have an inhibitory effect on the releasing process of insulin from pancreatic β cells and that P-607 have a stimulatory effect on the same process.
