Description

[0001] The present invention relates to a pharmaceutical composition for preventing or treating obesity, which comprises an extract of soybean germinated embryo,

The present invention relates to a pharmaceutical composition for preventing or treating obesity, which comprises a soybean germinated embryo extract, and more specifically, to a pharmaceutical composition for preventing or treating obesity comprising a soybean germinated embryo extract or a fraction thereof, To a food composition for preventing or ameliorating obesity comprising a soybean germinated embryo extract or a fraction thereof, and a feed composition.

Obesity or obesity is a state in which excess fat is accumulated in the body and refers to a state in which the number of adipocytes in adipose tissue is increased or the size of adipocyte is increased and fat is increased. Although obesity itself may not be a problem, the resulting social impairment and secondary complications caused by excessive fat are serious. For example, obesity causes diseases such as hypertension, hyperlipidemia, heart disease, diabetes, atherosclerosis, fatty liver, joint disorders, arthritis, sexual dysfunction, and cancer. Particularly, since the fat cells once formed are reduced in size, they are not removed naturally and remain permanently in the body, so that interest in the prevention and treatment of obesity is increasing.

Balanced diet and regular exercise are necessary to prevent or treat obesity and maintain proper weight. Recently, there have been cases where obesity is treated by taking drugs that reduce fat absorption. Such diet drugs may cause side effects such as cardiovascular diseases such as hypertension and stroke, Occasionally. In the case of severe obesity, surgical procedures such as surgery to remove fat or gastroplasty or stomach band insertion to limit the amount of food that can digest the body are performed, but the side effects of the surgery or complications resulting therefrom are reported And even deaths have been reported.

Accordingly, it is urgently required to develop a therapeutic agent for obesity which has less toxicity and side effects. Recently, alternative therapies using various active ingredients derived from natural products such as herbal medicines and foods or methods for producing various extracts have been studied. Examples thereof include a composition for prevention and treatment of obesity including extracts of herbal medicines (Korean Patent Laid-Open Publication No. 2015-0105563) or a composition for improving, preventing or treating obesity including garlic and herbal extract (Korean Patent Laid- 0085543) have been developed. However, development of a natural pharmaceutical composition or a raw material thereof, which has superior therapeutic effects and less side effects than conventional synthetic pharmaceutical compositions for obesity, has not yet been developed.

Under these circumstances, the present inventors have made intensive research to develop a therapeutic agent for obesity using a natural-derived component, and as a result, it has been found that an extract of a soybean germinated embryo produced by germinating an abandoned soybean embryo in the process of producing a processed product using soybean, Inhibiting the differentiation, reducing the size of adipocytes, and converting white adipocytes into brown adipocytes, thereby inhibiting the accumulation of unnecessary fats in vivo. Thus, the present invention has been completed.

It is an object of the present invention to provide a pharmaceutical composition for preventing or treating obesity comprising a soybean germinated embryo extract or a fraction thereof.

It is another object of the present invention to provide a method of preventing or treating obesity comprising the step of administering the composition to a subject other than a human.

It is still another object of the present invention to provide a food composition for preventing or ameliorating obesity comprising a soybean germinated embryo extract or a fraction thereof.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example  1. Beans Germination embryo  Evaluation of cytotoxicity of extracts

In order to prepare the soybean germinated embryo extract, the soybean germinated embryo prepared according to the previous study of the present inventor was used. Specifically, the soybean embryo was immersed in running water and germinated. After about 24 hours, the soybean germinated embryo was harvested, lyophilized and powdered to obtain a soybean germinated embryo powder. The resulting soybean germinated embryo powder was extracted by adding a fermented syrup, followed by filtration to obtain a liquid component, and the liquid component was lyophilized to obtain a soybean germana extract.

Then, in order to confirm the safety of the soybean germinated embryo extract, cytotoxicity of the extract to the cells was evaluated. Specifically, the lipogenic precursor cell line 3T3-L1 was subcultured in a 96-well plate at a density of 2 × 10 2 cells / well, and seed extracts of 50, 100, 200, 300, 400 and 500 μg / And cultured for 24 hours or 72 hours. After the completion of the incubation, the water-insoluble formazan formed by the addition of the MTT solution was dissolved in a dimethyl sulfoxide solution, and the optical density (OD value) of the dissolved formazan at 595 nm was measured. The relative cell viability (%) was assessed by measurement.

As a result, as shown in Fig. 1, it was confirmed that the soybean germinated embryo extract did not show cytotoxicity at all concentrations. As a result, the soybean germinated embryo extract of the present invention was found to be a safe substance free from harm to human body.

Example  2. Soybean for fat cell differentiation Germination embryo  Analysis of the effect of extracts

Example  2-1. bean Germination embryo  Analysis of lipid-lowering activity of extracts

To examine the effect of the extract on obesity treatment, the effect of soybean germinated embryo extract on the degree of adipocyte differentiation was analyzed.

3T3-L1 cells (Korean Cell Line Bank, Korea) were purchased from a fetal bovine serum (FBS) and 1% antibiotics (100 U / ml penicillin and 0.1 mg / mL streptomycin) ) In DMEM (Dulbecco's modified eagle medium) medium at 37 ° C under 5% CO 2 (95% air).

The cultured 3T3-L1 cells were treated with soybean germinated embryo extracts at a concentration of 50, 100, 200, 300, 400 and 500 / / mL, and the differentiation inducers (FBS, IBMX, dexanmethasone and Insulin) for 72 hours to differentiate into adipocytes. At this time, adipocyte without any substance was used as a control group and adipocyte treated with the same concentration of CLA (conjugated linoleic acid) was used as a comparative group.

As a result, as shown in FIG. 2, differentially treated control adipocytes (control + insulin) treated with insulin compared to control non-differentiated control fat cells (control) showed an increase in accumulated fat in the cells. In addition, it was confirmed that the soybean germinated embryo extract reduced the fat content of the differentiated adipocytes to the extent similar to that of CLA (conjugated linoleic acid) Was found to be better as the concentration of the extract increased. In addition, the soybean germinated embryo extract of the present invention was superior to the extract obtained by germinating the soybean itself, in that the fat cell differentiation inhibition effect was superior and the fat accumulation inhibition effect was also superior.

Example  2-2. Soy bean for fat cell differentiation Germination embryo  Analysis of the effect of extracts

In order to analyze the effect of soybean germinated embryo extract on differentiation of adipocytes, the effect of the extract on the expression of biomarkers associated with adipocyte differentiation was examined.

Specifically, the degree of protein expression of PPARγ, SREBP-1c and CEBPα, genes promoting differentiation of adipocytes, was confirmed by Western blotting.

As a result, as shown in FIG. 3, the expression of PPARγ, SREBP-1c and CEBPα was decreased in the experimental group treated with the extract, as compared with control cells treated with DMSO. These results indicate that the soybean germinated embryo extract can inhibit fat cells from accumulating fat by inhibiting differentiation of adipocytes. In addition, when the soybean germinated embryo extract of the present invention was compared with the extract (SG) obtained by germination of the soybean itself, it was confirmed that the gene expression suppressing effect was superior and the fat accumulation inhibiting effect was also superior .

Example  3-1. Soybeans for fat cell size Germination embryo  Analysis of the effect of extracts

In order to evaluate the effect of the extract on obesity, the effect of soybean germinated embryo extract on the fat cell size of obesity - induced animal models was analyzed by surgically removing ovaries. After menopause, as the amount of hormone secretion decreases, the basal metabolic rate decreases, and as fat decomposition decreases, the likelihood of obesity increases.

Specifically, the ovaries were removed from the ovaries by using 8-week-old female C57BL / 6 mice. For ovariectomy, a 1-2 cm skin incision was made in the lower middle region of the abdomen and forceps were applied to the ovaries (ovary) and oviduct (oviduct). One week after ovariectomy, randomized grouping was divided into randomized groupings using body weight measurement. Sonde was orally administered with 0.1, 1 and 5 mg / kg of soybean germinated embryo extracts six times a week.

After the end of the administration, the adipose tissue surrounding adipose tissue was removed, fixed with 10% formalin, embedded in paraffin, and the adipose tissue was sectioned to 4 μm. Then, the specimens were stained with HE (Hematoxylin and Eosin) staining. Observation of adipocytes was performed at a magnification of 400 × under a microscope. The lengths of long and short axes were measured for 10 cells in one field of view. The mean value of the long axis and short axis observed at 3 fields per individual was calculated and the average value of the groups was calculated.

As a result, as shown in FIG. 4, it was confirmed that the short axis and the long axis length of the adipocyte were increased in the negative control group (OVX) caused by menopause due to obesity as compared with the normal control group (con). On the other hand, it was confirmed that the diameter of the adipocyte was decreased in the test group administered with the extract, and the higher the concentration of the extract was, the higher the concentration of the extract (5 mg / kg / day) In the experimental group, the size of adipocytes was decreased to a level similar to that of the normal control group.

Example  3-2. Beans for white adipocytes and brown fat cells Germination embryo  Analysis of the effect of extracts

Since white adipocytes are responsible for the development of adult diseases such as diabetes or obesity, brown adipocytes play a role in preventing obesity by burning fat as energy. Therefore, in order to evaluate the therapeutic effect of the extract on obesity, The effect of ovariectomy on white adipocytes or brown adipose cells in obesity - induced animal models was analyzed.

Specifically, the soybean germinated embryo extract was administered to an obesity-inducing animal model according to the method of Example 3-1, and the number of white adipocytes and brown adipocytes of the animal were examined. Immunohistochemistry using fatty acid oxidation-related UCP1 (mitochondrial uncoupling protein 1) protein was performed on adipose tissue cells, and brown adipocytes (UCP1) showing positive UCP1 response at three fields per subject at a microscope magnification of 200 times Were measured using LAS image analysis software.

As a result, as shown in FIG. 5, it was confirmed that the negative control group (OVX) and the normal control group (con) caused by obesity caused by menopause had fewer cells showing UCP1 positive reaction around and inside gonadal fat . On the other hand, in the test group administered with the extract, the number of UCP1-positive cells was increased compared to the negative and normal control groups, and at the same time, the size of white adipocytes decreased. This effect was better as the concentration of the extract was higher, and the number of brown adipocytes increased about 3.2 times in the experimental group administered with the high concentration of the extract (5 mg / kg / day) Respectively.

From the above results, it was found that the soybean germinated embryo extract showed a decrease in the size of white adipocytes and saturating the cells with brown adipocytes, thereby suppressing accumulation of adipocytes.
