  • the mice were bred with powdered feed “CE-2” (Clea Japan) five days before the start of the test. Fasting was performed from 9:00 am to 1:00 pm on the first day of the test, and then heparin was collected (50 L) from the tail vein and weighed. Blood was kept in ice, and after centrifugation (10000 rpm, 5 minutes), the glucose and triglyceride concentrations in the obtained plasma were measured using glucose C-II Test Co. and triglyceride E Test Co. (Wako Pure Chemical Industries, Ltd.).
  • a group bred on a feed not containing the compound of the present invention was used as a control group, and pioglitazone represented by the formula (0) (mixing ratio: 0.020%) was used as a positive control compound.
  • the rate of change (%) in blood glucose and blood triglyceride value in each group was calculated by the following formula. The results are as shown in Table 1.
  • SSOmgZkg The compound of the present invention, shown in Table 1 was intraperitoneally administered and observed for one week. All of them survived.
  • the compound of the present invention showed an excellent blood glucose lowering effect and blood triglyceride lowering effect even when compared with the positive control compound.
  • the compound of the present invention did not cause lactic acidosis and did not cause excessive hypoglycemia. From this, the compound of the present invention is useful not only for the treatment of diabetes but also for various complications of diabetes and as a blood lipid lowering agent. In addition, all of these compounds are less toxic and safer than the effective dose.
