- Rat feed F2 manufactured by Funabashi Collins Co., Ltd. was fed orally and freely fed for 8 weeks to rats of 4 to 6 rats in each group. 17.3 g). The control group received only feed. Blood was collected every two weeks and its blood glucose, plasma lactate, and plasma triglyceride levels were measured.
- the measurement was performed by a potential measurement method using a glucose oxidase-immobilized electrode using a Darco Roda-G XT (manufactured by A & T), an absorbance measurement method using a lactate reagent (Lactate Reagent, manufactured by Sigma), and The test was performed by an absorbance measurement method using a coat triglyceride E test.
- the glycated hemoglobin ratio was also measured with DCA-200000 (manufactured by Bayer Medical) at the end of the administration and at the time of blood collection two weeks after the drug was stopped.
- the blood glucose level of the control group began to increase at the age of 10 weeks (4 weeks after the start of dosing), and was 30 Omg / d 1 or more at the age of 12 to 14 weeks (6 to 8 weeks of the start of dosing). Reached the point where diabetes had developed.
- the increase in blood glucose level was suppressed in a dose-dependent manner.
- the administration of Compound A was stopped, the blood sugar level that had been suppressed increased, the blood sugar level became as high as that of the control group, and diabetes occurred. Therefore, it was shown that the administration of Compound A clearly suppressed the onset of diabetes in GK rats. From Fig.
- the diabetes mellitus suppression effect of compound A is an indicator of glycemic control. It was also expressed by the value of glycated hemoglobin. That is, the ratio of glycated hemoglobin in the compound A-administered group decreased in a dose-dependent manner of compound A, indicating that the onset of diabetes was prevented.
- Glucogenesis is controlled by several rate-limiting enzymes, and one of these rate-limiting enzymes, FBPase, is localized in fF kidney and kidney and is an essential enzyme for gluconeogenesis. In other words, it is thought that there is a close relationship between diabetes and FBPase activity in the liver.
- an FBPase inhibitor when administered orally, it is first exposed to the liver at a high concentration through the portal vein.Therefore, the FBPase inhibitor strongly suppresses hepatic gluconeogenesis and prevents diabetes. It is considered that the effect was exhibited. In addition, the results show that FBPase inhibitors are also effective in suppressing metabolic diseases associated with hyperlipidemia—macrovascular disorders.
- the lactic acid value was almost constant during the test period, and there was no difference between the control group and the compound A administration group.
- Compound A is considered to be safe to use without the side effects that increase lactic acid found in metformin.
- no gastrointestinal symptoms, such as diarrhea, were observed in any group throughout the observation period. Therefore, Compound A is considered to have no gastrointestinal side effects such as metformin.
- metformin is likely to cause gastrointestinal symptoms because it has a tendency to accumulate in the digestive tract.
- One hour after administration of A a 50% glucose solution is orally administered so as to be 2 g / kg.
- Blood is collected from the tail vein 1 hour before glucose administration, immediately before administration, and 30, 60, 120, and 240 minutes after administration. The blood glucose level is measured by a potential measurement method using a glucose oxidase-immobilized electrode using a Darco Roda GXT (manufactured by A & T).

- a 50% glucose solution manufactured by Otsuka Pharmaceutical Factory
- the control group was orally administered only with a 50% dalcose solution to give 2 gZkg.
- Blood was collected from the tail vein just before glucose administration, 0.5, 1, 2, and 4 hours after administration, and blood glucose was measured using a Darco Roda GXT (manufactured by A & T) potential measurement method using a glucose oxidase-immobilized electrode. Measured.
- the time after the administration of Compound A was plotted on the horizontal axis, and the blood glucose level of each individual was plotted on the vertical axis, and the area under the curve of the graph obtained by connecting each point with a straight line was calculated. From the calculated area under the blood glucose curve, the average value and standard error were calculated for each group, and are shown in FIG. From Fig.
- compound A which is an FBPase inhibitor, is useful as a therapeutic or prophylactic agent for IgG.
- a 6-week-old GK rat (Nippon Charles River), a non-diabetic IGT, was fasted overnight, and then compound B (10 OmgZkg or 30 OmgZkg) was orally administered, and compound B administration 1 After an hour, a 50% glucose solution (manufactured by Otsuka Pharmaceutical Factory Co., Ltd.) was orally administered so as to be 2 gZkg. To the control group, only a 50% glucose solution was orally administered to 2 gZ kg. Blood was collected from the tail vein immediately before, 0.5, 1 and 2 hours after glucose administration, and the blood glucose level was measured by Darcoloda GXT (A & T). Was measured by a potential measurement method using a glucose oxidase-immobilized electrode.
- compound B which is an FBPase inhibitor, is useful as a therapeutic or prophylactic agent for IgG.
- glucose intolerance in the diabetic state there are roughly three forms. Specifically, these include the promotion of sugar utilization in the living body, the promotion of sugar excretion from the living body, and the suppression of sugar production in the liver. Furthermore, hepatic gluconeogenesis is involved in gluconeogenesis, and FBPase inhibitors are thought to suppress hepatic gluconeogenesis by inhibiting its rate-limiting enzyme, FBPase. Therefore, it is considered that inhibition of FBPa se suppresses saccharide production in the liver, and as a result, IGT is improved.
- the powders of the above components are mixed well and compressed into tablets each weighing 15 Omg. If desired, these tablets may be coated with a sugar or film.
- the powder of each component shown above is mixed well, moistened with pure water, granulated by a basket granulator, and dried to obtain granules.
- the medicament containing the FBPase inhibitor of the present invention has an excellent preventive effect on the onset of diabetes, and further has no side effects (increased lactate level, gastrointestinal symptoms, etc.) as seen with metformin. It is useful as a safe and long-lasting diabetes prevention drug.
- the medicament containing the FBPase inhibitor of the present invention is also useful for the treatment and Z or prevention of IGT (particularly, IGT which is widely seen in the process of progressing to diabetes). And, the medicament containing the FBPase inhibitor of the present invention is also useful for preventing IGT-related diseases (eg, diabetes, diabetic complications, hypertension, arteriosclerosis, macrovascular disorders, etc.).
- IGT-related diseases eg, diabetes, diabetic complications, hypertension, arteriosclerosis, macrovascular disorders, etc.
- hyperlipidemia main symptoms include, for example, hypertriglyceridemia and hypercholesterolemia
- main symptoms include, for example, hypertriglyceridemia and hypercholesterolemia
- hyperlipidemia Is also a risk factor, and it is also useful as a prophylactic for diseases such as macrovascular disease.
