15 [0002]
With an increase of people who lead a life with excess energy intake that is more than the amount necessary for vital activities and that is due to factors, such as intake of high• calorie meals and beverages, a reduced amount of daily exercise,
20 and reduced basal metabolism associated with muscle weakness, the
number of young people as well as middle-aged and elderly people who develop diabetes or exhibit insulin resistance is increasing. The aging of fat cells is also known to cause insulin resistance. Elderly people with reduced basal metabolism and a reduced
25 exercise amount also have a high risk of developing diabetes.
[0003]
In this way, changes in everyday life and a shift towards older societies tend to lead to an explosive increase in diabetic patients every year, and the number of people with
30 abnormal blood sugar metabolism, who are people with pre-diabetes, is also considered to be several times larger than the number of diabetic patients. In fact, similar trends are also apparent from the National Health and Nutrition Examination Survey and Diabetes Survey. An increased diabetic population in Japan is considered
35 to be a serious problem. Under these circumstances, efforts "not
to exacerbate an existing pathological condition in diabetic patients" and "not to develop diabetes in insulin-resistant people" are important, because diabetes is a disease that cannot be fundamentally cured.

As such efforts, there are "methods for preventing the onset of diabetes or treating diabetes by controlling the blood sugar level within a normal range." Specifically, there are methods such as diet therapy, exercise therapy, and
10 pharmacotherapy. Methods using one or a combination of these therapies are actually performed according to the circumstances and condition of the target patient. อย่างไรก็ตาม, it is often difficult to continue diet therapy that restricts calorie intake or exercise therapy that requires performing exercise for a
15 certain period of time or longer. In particular, there are more and more cases in which it is difficult, with the above therapies alone, to treat elderly people who not only have reduced basal metabolism, but also a significantly reduced amount of exercise with significantly reduced exercise capacity. On the other hand,
20 pharmacotherapy also cannot be a satisfactory combating method from the viewpoint of preventing healthcare cost increase, and is difficult to be used as a method for preventing the onset of diabetes.
(0005]
25 Accordingly, with a focus on sugar metabolism in skeletal muscle that severely affects blood sugar metabolism, attempts have been made to develop means for dramatically enhancing diabetes onset-preventing effects and diabetes pathology-improving effects by being used alone or together with
30 conventional therapeutic or preventive methods.
[0006]
One of the physiological functions that lower blood sugar level is a "metabolism function through uptake of blood sugar from blood vessels (blood) into skeletal muscle." The
35 following action is known as a mechanism of this function:
"skeletal muscle contraction stimulates phosphorylation (activation) of intracellular AMP kinase, which causes translocation of glucose transporter 4 in the cytoplasm into the cell membrane, thus resulting in blood sugar uptake into skeletal
5 muscle cells." It has also been revealed that that sugar uptake
into skeletal muscle cells does not necessarily require skeletal muscle contraction, but is caused by activation of AMP kinase. Accordingly, even when exercise cannot contract skeletal muscle, the function of blood sugar uptake into skeletal muscle is
10 potentially achievable just like exercise is performed. In recent years, while focusing on this point, several "attempts to reduce blood sugar concentration by oral intake of a substance that activates AMP kinase" have been proposed (Patent Literature (PTL)
1 and Patent Literature (PTL) 2).
