JP5080011B2 - Composition for increasing glutathione peroxidase activity - Google Patents

Description

  The present invention relates to a composition for increasing glutathione peroxidase activity containing one or two selected from pantethine and folic acid.

  Humans obtain energy from oxygen by breathing, but a few percent of the oxygen they take is converted into active oxygen and free radicals in the body. In recent years, it has been clarified that oxidative stress through the generation of these reactive oxygen species works disorganously in the living body and is associated with many diseases such as carcinogenesis, inflammation, arteriosclerosis, diabetes and obesity. Reactive oxygen species generated in tissues and cells due to various oxidative stresses are affected by the endogenous antioxidant defense system of the living body and exogenous antioxidants taken from outside the body. Erasing and protecting herself. These active oxygen species include superoxide, hydroxy radicals, hydrogen peroxide, singlet oxygen and the like. Superoxide is decomposed into hydrogen peroxide by superoxide dismutase (SOD), and hydrogen peroxide is further decomposed into water by glutathione peroxidase (GPx) and catalase (see, for example, Non-Patent Document 1).

  If this series of detoxification processes is not sufficiently performed due to aging or other causes, some of the superoxide radicals and hydrogen peroxide combine with intracellular copper and iron to oxidize the strongest active oxygen. Hydroxyl radicals that are extremely harmful to a living organism with power are generated. This detoxification is done by GPx and antioxidants. Hydroxyl radicals are also known as the cause of degeneration, aging, carcinogenesis and arteriosclerosis of biological membranes by oxidizing lipids in the body to produce lipid peroxides. GPx and antioxidants are also responsible for lipid peroxide detoxification (see, for example, Non-Patent Document 1).

  It is also known that hydrogen peroxide is a weak carcinogen or promoter (Non-Patent Document 2).

  On the other hand, exposure to ultraviolet rays (UV) such as sunburn also generates superoxide, singlet oxygen, hydroxyl radicals by UV-B exposure, and hydrogen peroxide by UV-A exposure, causing wrinkles, pigmentation, DNA damage, and skin cancer induction. Cause non-patent document 3 (Non-patent Document 3). Further, it has been found that catalase is inactivated by UV-A irradiation (Non-Patent Document 4), suggesting an important role of GPx in the suppression of skin damage caused by ultraviolet exposure.

In addition, there are the following reports on GPx and diseases.
1) As a result of investigating the risk of cardiovascular events related to GPx and SOD activity in 636 patients suspected of having coronary artery disease, this shows a negative correlation with GPx activity, but may not be related to SOD activity It has been reported (Non-Patent Document 5).
2) GPx not only protects the host directly from active oxygen, but also protects the host from disease by preventing the virus from being toxic by active oxygen even in non-toxic virus infection (Non-patent Document 6).
3) GPx has a stronger protection against oxidative damage than SOD and catalase. When a myocardial infarction was produced in a GPx gene overexpressing mouse, remodeling and heart failure were suppressed and the survival rate was improved (Non-patent Document 7).
4) It is said that GPx activity is reduced under conditions such as selenium deficiency, malignant tumor, artificial dialysis, liver damage, and decreased immunity (Non-patent Document 8).
5) It is said that patients with cancer, ischemic heart disease and cerebrovascular disorder have lower GPx activity than those who do not (Non-patent Document 9).

On the other hand, there are the following reports on the efficacy of pantethine.
1) Serum cholesterol and triglyceride lowering action and experimental atherosclerosis progression inhibiting action are known (Non-patent Document 10).
2) Lipid peroxide lowering action as an antioxidant is known (Non-patent Document 11).

  As for folic acid, a blood homocysteine lowering action and an antioxidant action independent of this action (LDL oxidation inhibiting action) have been reported (Non-patent Document 12).

  As described above, panthetin is known to have an anti-arteriosclerotic effect based on blood lipid lowering action, and folic acid is known to have an anti-arteriosclerotic action based on blood homocysteine lowering action and lipid peroxide lowering action. Furthermore, both pantethine and folic acid appear to be recognized as antioxidant vitamins.

However, there are currently no reports that pantethine or folic acid improved GPx activity. Furthermore, there is no report or suggestion that pantethine or folic acid was effective in eliminating or inhibiting the hydrogen peroxide, hydroxy radical, and lipid peroxide, which are GPx-like actions.
