Diabetes is the third most dangerous disease worldwide and is the fifth leading cause of death in Korea.

Diabetes is not a single disease but a metabolic disorder that shares features of hyperglycemia. In diabetes, hyperglycemia is caused by insulin secretion, defects in insulin activity, or both.

Diabetes mellitus is divided into type 1 and type 2 diabetes, characterized by the deficiency of insulin secretion by pancreatic beta cell destruction caused by autoimmune attack, accounting for about 10%. Type 2 diabetes is caused by inadequate compensatory responses to insulin secretion by the pancreatic beta cells and terminal resistance to insulin activity, accounting for 80-90% of the cases.

Insulin therapy and oral hypoglycemic agents are the most commonly used methods for the treatment of diabetes.

Higher blood sugar levels lead to various complications, so blood glucose should be lowered to prevent complications. The first principle in the treatment of diabetes is to maintain normal blood sugar, which requires insulin to play a normal role.

Orally administered diabetes drugs can be divided into two groups: promoting insulin secretion prior to their action, increasing the activity of insulin, making less glucose in the body, controlling insulin production and promoting the use of glucose. In addition, insulin is administered mainly as an injection. Recently, studies on insulin that is attached to the body have been carried out.

Example 1. Preparation of fractionated mushroom of Great king

50 g of dried mushroom ( Pleurotus nebrodensis ) was extracted twice with 80% (w / w) ethanol in a reflux condenser at 80 ° C to obtain 24.11 g (yield: 48.22%) of mushroom extract. 15 g of the thus obtained mushroom extract was dissolved in 150 ml of water and then the chloroform (CHCl 3 ) layer was separated three times. The resulting chloroform layers were combined and concentrated under reduced pressure to obtain 0.17 g (yield: 1.13%) of the fraction of chloroform of Dae-Wang Mushroom in powder form. Ethyl acetate (CH 3 COOC 2 H 5 ) and water (H 2 O) were sequentially added to the remaining water layer and fractionated in the same manner as above. The mixture was concentrated under reduced pressure and lyophilized to obtain 1.19 g (yield: 7.93%) and water fraction (12.23 g, yield: 81.53%).

Example 2. a-glucosidase inhibition

α-glucosidase is an enzyme that induces glucose degradation in the body and is most directly involved in the increase of blood glucose by decomposing the disaccharide into monosaccharides. Therefore, in order to confirm the anti-diabetic function of the fraction of mushroom, the following experiment was conducted.

First, the? -Glucosidase inhibitory activity was measured by applying a nitrophenol assay. 50 μl of 0.3 U / ml yeast α-glucosidase enzyme solution and 100 μl of 10 mM p-nitrophenyl-α-D-glucopyranoside were added to the chloroform fraction, ethyl acetate fraction and water fraction 2 , 10, 50 μg / ml and 0.2 M phosphate buffer (pH 7.0), and incubated at 37 ° C. for 20 minutes. Then, 100 μl of 0.1 M Na 2 CO 3 was added to stop the reaction and the absorbance was measured at 405 nm. At this time, acarbos (10 mM) was used for the activity comparison. The inhibition rate of enzyme activity was calculated by the following equation. The results are shown in Fig.

? -glucosidase inhibitory activity (%) = {1- (absorbance of sample-treated group / absorbance of control group)} x 100

As shown in Fig. 1, it was confirmed that the group treated with the Chloroform fraction and the fraction containing the ethyl acetate fraction of manganese chloride had excellent inhibitory effect on the enzyme α-glucosidase.

Example 3 Inhibition of Protein Tyrosine Phosphatase (protein-tyrosine phosphatase 1B, PTP-1B)

When insulin binds to its receptor, it induces glucose metabolism and glycogen synthesis through IRS-1 (Insulin receptor substrate-1) and PI3K (Phosphoinositide 3-kinase) pathway. At this time, the enzyme that interferes with the insulin-receptor binding is PTP-1B, and inhibiting the activation of PTP-1B induces insulin action. Thus, in the present Example, the following experiment was conducted to confirm antidiabetic function through inhibition of PTP-1B of the fraction of Daehwang mushroom.

PTP1B enzyme activity was measured using para-nitrophenyl phosphate (p-NPP) as a substrate. To the buffer solution containing 50 mM citrate buffer (pH 6.0), 0.1 M NaCl, 1 mM EDTA and 1 mM DTT, 20 mM p-NPP, PTP1B (0.05 g) and the ethanol extract of Daehwang mushroom, chloroform fraction, ethyl Acetate and water fractions were added at a concentration of 0.8 and 4 μg / ml, respectively, and incubated at 37 ° C. for 30 minutes. Then, 10 μl of 10 N NaOH was added to terminate the reaction. At this time, guava leaf extract (4 ㎍ / ml) was used as a control. The absorbance of p-nitrophenol was measured at 405 nm. The enzyme inhibition rate (%) was calculated by adding only the enzyme and the substrate to the buffer solution, measuring the value obtained by adding 100% to the enzyme solution, and calculating the value as 0%. The results are shown in Fig.

As shown in FIG. 2, it can be confirmed that the fraction of the mushroom of the invention, which is an active ingredient of the present invention, inhibits the PTP-1B enzyme more effectively in a concentration-dependent manner compared to the extract of the mushroom of the great king. In particular, it was confirmed that the fraction of Chloroform fraction of Dae-Wang Mushroom showed more than 2-fold inhibition of PTP-1B enzyme activity at a concentration of 4 μg / ml compared with other fractions. In addition, it was confirmed that the PTP-1B enzyme inhibitory activity was significantly superior to the control group treated with Guava leaf extract at a concentration of 4 / / ml in the chloroform fraction and the ethyl acetate fraction treated group.

Example 4. Cell viability

In order to analyze the cell viability of the mushroom fraction prepared in Example 1, an experiment was conducted using MTT (3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyl tetrazolium bromide) assay.

Rin-m5F (rat insulinoma β-cell) cells were purchased from ATCC and cultured in RPMI-1640 medium supplemented with 10% fetal bovine serum (FBS) and 1% penicillin at 37 ° C and 5% CO 2 . The cultured RIN-m5F cells were inoculated into a 24-well plate at a concentration of 3 × 10 5 cells / well and cultured in an incubator for 24 hours. The extracts of the mushroom and its fractions prepared in Example 1 4, 20, and 100 μg / ml, and measured using MTT buffer after 24 hours. The results are shown in Fig.

As shown in FIG. 3, it was confirmed that the cells were survived up to 100 μg / ml in the ethanol extract of Dae-Wang Mushroom, the chloroform fraction, the ethyl acetate fraction and the water fraction.

Example 5. Insulin secretion ability

As a result of the cell viability test of Example 4, the cell viability was excellent at the whole concentration of Dae-Wang mushroom fraction. Therefore, the medium concentration value (4, 20 占 퐂 / ml) Respectively.

First, Rin-m5F (rat insulinoma β-cell) cells were seeded in a 6-well plate at 3.0 × 10 5 per well and cultured in complete medium for 3 days. Krebs-Ringer bicarbonate KRB) buffer. Then, the KRB buffer was added and the mixture was incubated at 37 ° C for 40 minutes. Then, the buffer was removed, and a normal control vehicle (Vehicle), a glucose control (Glucose 16.7 mM), KCL 25 mM, 20 / / ml) were added and incubated for 1 hour. The supernatant was then centrifuged at 4 ° C for 10 min and the supernatant was collected and stored at -20 ° C. The amount of insulin secreted from the cells was measured with an insulin RIA kit, and the concentration of the cell protein in each well was measured to calculate the amount of insulin secreted per each unit of gram protein. The results are shown in FIG.

As shown in FIG. 4, it was confirmed that the insulin secretion level in the group treated with the extract of Chloroform fraction of Dae-Wang mushroom of the present invention was excellent at the concentrations of 4 / / ml and 20 / / ml. Particularly, in the case of the concentration of 20 / / ml, it was confirmed that the treated group of Chloroform fraction of Dae-Wang mushroom showed insulin secretion improved by 1.5 times or more as compared with the group treated with the extract of Dae-Woo mushroom. It was predicted that the chloroform fraction could be effectively used for prevention, improvement and treatment of diabetes.
