Description

A method of separation to sulforaphene from Raphanus sativus L and the use of sulforaphene}

The present invention relates to a process for the preparation of sulfolafens isolated from radish and uses thereof.

The gastric mucosal layer that protects the stomach is susceptible to damage from a variety of factors. Bacteria [Suzuki, such as a typical attack factor NSAIDs (NSAID), such as acid, alcohol, aspirin, Helicobacter pylori (Helicobacter pylori). M. and S. Miura, Nippon Rinsho, 15 (12), 3154-3158, 1993], stress-induced microcirculation disorders and hypotension of gastric mucosa [Tadaoki Mizuno, Yokohama Med. Bull. , 38 (3,4), 87-97, 1987]. Due to these factors, when the mucosal layer is damaged, inflammation is accompanied by erosion, redness, bleeding, and edema. In addition, the duodenum, which is directly connected to the stomach, may cause inflammation and duodenal ulcer by similar factors.

On the other hand, in order to treat inflammation and ulcers of the stomach and duodenum caused by these attack factors, a drug having the effects of inhibiting gastric acid secretion, inhibiting proliferation of Helicobacter pylori, promoting mucus secretion, promoting epithelial cell regeneration, and anti-inflammatory . Currently, the most representative gastritis and gastric ulcer drugs are H2 antagonists and proton pump inhibitors, which have the effect of inhibiting gastric acid secretion, and have proven excellent effects in clinical practice. [J Int Med Res 17 (suppl) 9A, 1989 Meth Find Exp Clin Pharmacol 11 (suppl 1) 87, 1989; N Eng J Med 323: 1672, 1990. However, these gastric acid secretion inhibitors are problematic for high recurrence rate after the end of the administration (Drug Intell Clin Pharm 21: 493, 1987, Gut 30: 449, 1989 Yale J Biol Med 65: 649, 1992).

Mucosal protective agents, such as promoting normal regeneration of mucosal tissues to resist the re-attack of gastritis-inducing factors to reduce the high gastritis recurrence rate, a disadvantage of fast-acting gastric acid secretion inhibitors, are an important part of the treatment of gastritis . Currently, drugs such as rebamipide and sofalcone have been developed as gastric mucosa protective agents, but generally have shortcomings, high doses, and need to be taken for a relatively long time.

On the other hand, isothiocyanates of cruciferous crops are already well known sulfforaphane (sulforaphane) isolated from broccoli, and the sulforaphane has been reported through many documents.

However, there is no report on a study that separates sulfolafen (Formula 1) structurally different from sulforaphane (Formula 2) from radish as in the present invention.

[Formula 1]

[Formula 2]

Accordingly, the present inventors have succeeded in separating the sulforaphene, which is an isothiocyanate material different from sulforaphane, from radish for the first time, and it is also confirmed that the sulforaphene does not decrease its content as the growth is extended, unlike sulforaphane. Thus, the present invention has been completed. In addition, the sulfolafen has been shown to inhibit the production and growth of Helicobacter bacteria.

Accordingly, an object of the present invention is to provide a method for separating sulfolafen from radish.

Another object of the present invention is to provide a composition for preventing and treating diseases related to Helicobacter infection, which contains sulfolafen as an active ingredient.

Another object of the present invention is to provide a health food containing sulfolafen as an active ingredient.

In order to solve the above problems, the present invention

Hereinafter, the present invention will be described in detail.

The present invention is to isolate the sulforaphene (sulforaphene) from radish, by revealing the effect of inhibiting the production and growth of Helicobacter pyroli bacteria involved in causing gastritis, gastric ulcer and gastric cancer A method for separating sulfolafen from radish and the use of sulfolafen.

The method for extracting sulfolafen from radish according to the present invention will be described in detail below.

First, the radish is homogenized with distilled water, and then hydrolyzed at 35 to 40 ° C. for 1 to 5 hours. The radish includes all of the roots, the maturation of the leaves or the shoots, but attempts to extract each part by performing a sampling. At this time, the state of the solution is the most common chemical structure of isothiocyanates form known to have anti-cancer effects in neutral conditions by hydrolysis of glucosinolates in which nothing is hydrolyzed under neutral conditions. It is preferable for the production, and if the hydrolysis temperature and time is out of the above range, the yield of the material to be separated is insufficient, and when the hydrolysis is prolonged for a long time, the anti-cancer property is not revealed or the effect of nitrile or epitionitrile is not effective. There is a problem that the recovery rate of isothiocyanate, which is decomposed by or the like and is known for its anticancer effect, is drastically reduced.

The hydrolyzate is centrifuged at 6000-10000 rpm for 20-30 minutes to obtain a supernatant, followed by liquid-liquid extraction with a solvent having a very low affinity for water. As the extraction solvent of the target material, dichloromethane or chloroform is preferable.

Water of the solvent extract is removed by adding sodium sulfate and then concentrated under reduced pressure at 30 ~ 40 ℃ using a nitrogen pressure reducer.

In addition, in order to fractionate sulfolafen and such nonpolar substances for easy analysis, the extract eluted with methanol is concentrated under reduced pressure at 40 to 50 ° C. through a solid phase extraction method. The hydrolyzate was extracted with an organic solvent and then collected through a solid phase extraction method to obtain a very pale yellow green or pale yellow substance, which was identified as sulfolafen.

It was confirmed that the isolated sulfolafen inhibits the production of Helicobacter bacteria, it can be prepared a drug for the prevention and treatment of diseases related to Helicobacter infection containing it as an active ingredient. The disease associated with Helicobacter infection may include gastritis, gastric ulcer, gastric cancer, and the like.

The medicament is prepared by a conventional manufacturing method and formulated into tablets, capsules, etc. Among them, a combination of lactose, microcrystalline cellulose, magnesium stearate, and the like, which are used as bases in the manufacture of tablets, and sulfolafen 2 to 10: 1 When used in proportions of the present invention, a tablet having an activity for preventing and treating diseases related to Helicobacter infection can be prepared.

In the manufacture of such a drug, it can be used as an active substance itself, but can also be prepared as a powder, granules, capsules, etc. by mixing with a pharmaceutically acceptable carrier, forming agent, diluent, etc. Do. In addition, the sulfolafen according to the present invention can be changed according to body absorption, weight, age of the patient, sex, health status diet, administration time, administration method, excretion rate, severity of the disease and the like. In general, it is preferable to administer about 0.05 to 1 mg of sulfolafen per 1 kg of body weight. In addition, the formulated unit dosage form may be administered several times at regular intervals or by using a specialized dosage method according to the judgment of an expert who monitors or observes the administration of the drug as needed and the needs of the individual.

In addition, the present invention includes a health food containing sulfolafen as an active ingredient.

A health food is a food prepared by adding sulfolafen to food materials such as beverages, teas, spices, gums, confectionery, or encapsulated, powdered, or suspension, and when ingested, has a specific health effect. Meaning, unlike the general medicine has the advantage that there is no side effect that can occur when taking a long-term use of the drug as a food raw material.

Since sulfolafen according to the present invention has an excellent effect of inhibiting the production of Helicobacter bacteria, it is very useful for preventing and treating related diseases such as gastritis, gastric ulcer or gastric cancer.

Hereinafter, the present invention will be described in more detail based on the following examples, but the present invention is not limited thereto.

Example 1 Separation and Structure Verification of Sulforaphene

To 5 g of radish, 30 ml of distilled water was added, homogenization was performed for 1 minute, hydrolysis at 37 ° C. for 3 hours, and the supernatant obtained by centrifugation at 8000 rpm for 20 minutes was extracted, extracted three times with dichloromethane, and water was removed with sodium sulfate. It removed and the extract was obtained. The resulting solution was concentrated under reduced pressure at 2O < 0 > C at 35 [deg.] C. using a nitrogen depressurizer, followed by solid phase extraction using a sep-pak silica cartridge and eluted with 3 ml of methanol. 0.3 ml was used for analysis by concentration under reduced pressure at 45 ℃ using a nitrogen pressure reducer.

The extract was quantitatively and qualitatively analyzed using HPLC and GC-Mass equipped with an evarporative light scattering detector (ELSD). The conditions of the equipment are as follows.

First, HPLC was used for Gilson's 305 series, and the analytical column was equipped with Nucleosil 100-5C18 (150 ㅧ 4.6 mm) from Macherey-nagel. The isocratic mobile phase solvent method was used and the composition of the solvent was determined by weight ratio of water: acetonitrile: tert-butyl alcohol = 8: 1: 1 with 5 mM ammonium acetate. . The flow rate of the HPLC pump was 1 mL / min and the temperature of the column oven was maintained at 40 ° C. The condition of the detector was that the gas flow rate was 2 mL / min, and the temperature of the detector was maintained at 50 ° C., so that the gain was adjusted to 1.

GC-Mass assay conditions for qualitative analysis were adjusted using an HP5970 detector mounted on the HP5890. The column was equipped with a silica capillary column (DB-5, 0.25 mm 30 mm) and the oven temperature of GC was raised by 10 ° C. per minute from 50 ° C. to 250 ° C. The temperature of the injector was maintained at 250 ° C. and the mobile phase flowed helium gas at 0.8 mL / min. E.I. ranged from 70 eV and mass scan ranged from 40 to 500 m / z.

In particular, 5 g of samples collected only from cotyledons and hypocotyls from 7 to 11 days after sowing were grown to obtain 650 µg (yield 13%) of light green or pale yellow substance containing sulfolafen. As a result of structural analysis by HPLC and GC-MS, the material was analyzed by sulfolafen represented by the following Chemical Formula 1 by confirming that it is consistent with the standard material [FIG. 1 and FIG. 2].

[Formula 1]

Comparative Example 1: Separation of Sulforaphane

From broccoli Vertelli et al [Davide V., Maria P., Daniela B. and Agar M. 1998. Separation by solid phase extraction and quantification by reverse phase hplc of sulforaphane in broccoli., Food Chem. 63: 417-421.] Was isolated from the formula 2 120 ㎍ (yield 12%) per gram of sulforaphane in vivo.

[Formula 2]

Test Example 1: Comparison of Contents

The purpose of this study was to determine the growth days with the highest yields by comparing the sulforaphane and sulforaphene contents of each plant growth stage.

First, the radish and broccoli seeds were grown on a container containing wet tissue, and irrigated twice daily at 25 ° C. and 15 hours light conditions. Sampling was carried out by dividing the growth days of five shoots from 5th, 7th, 9th, 11th, and 14th day from the day of tooth densities.

The sulfolafen obtained by this extraction was an average of 145 µg.

The following Table 1 and Figures 3 to 6 show the change in the content of isothiocyanate material during the growth of broccoli, radish buds, young plants, matures.

TABLE 1

As shown in Figures 3 to 6 and Table 1, the sulforaphane separated from broccoli was confirmed that the content is reduced during the growth of the plant, the sulfolafens isolated from radish did not decrease during the growth of the plant .

This is in contrast to the tendency of sulforaphane, which is produced by the valueless plant individual to overcome external disturbances such as pests and herbivore attacks depending on the growth stage, as the content of sulforaphane decreases like the broccoli. In terms of antioxidant intake, it means that the extraction yield and potency of the material is very good.

Test Example 2: Confirmation of the inhibitory effect of the production of Helicobacter bacteria

In order to know the efficacy of sulforaphene that inhibits or inhibits the growth of Helicobacter pylori, an experiment was conducted to compare the antibiotic ability of sulforaphene with a known sulforaphane with an antibiotic, metronidazole, which inhibits the growth of Helicobacter pylori. Table 2 compares the antibiotic activity of sulfolafen and other treatments in the inhibition of growth of Helicobacter pylori specific strains. Table 2 demonstrates that the pylori strain-specific sulfolafens have efficacy equivalent to or greater than existing antibiotics.

TABLE 2

Test Example 3

Helicobacter pylori strains were grown in broth liquid medium at 37 ° C. in mass, and then the bacteria were collected and resuspended in PBS. Rats were treated with food (food) and water intake for 12 hours and then treated with pylori 10 ⁹ CFU / ml by administering 40 μl of Helicobacter pylori dissolved in PBS. Animals were anesthetized with metapan and sacrificed to directly culture the infection of the gastric membrane, followed by urease test [Y. Tokunaga et al, J Gastroenterol hepatol (2000) 12: 617-621] confirmed the infection of Helicobacter pylori. After confirmation, the extracted sulfolafen and other antibiotics were orally administered 20 mg twice a day. The following table 3 shows that rats infected with sulfofen penetrate the actual Helicobacter pylori improvement of gastric mucosa infection by urease test, and sulfofen is more effective than antibiotics in animals infected with Helicobacter pylori. Demonstrates or similar.

[Table 3]

Test Example 5: Oral Administration of Rats Acute Toxicity Test

Acute toxicity test was performed using 6-week-old SPF SD rats as follows.

Sulforaphene was dissolved in two animals per group and administered orally at a 400 mg / kg dose. After administration of the test substance, mortality, clinical symptoms, and changes in body weight were observed, and hematological and hematological examinations were performed. As a result, no significant clinical symptoms or dead animals were noted in all animals treated with the test substance, and no toxic changes were observed in weight changes, blood tests, blood biochemical tests, and autopsy findings. Therefore, sulfolafen according to the present invention did not show a toxic change to 400 mg / kg in all rats and the minimum lethal dose (LD ₅₀ ) of oral administration was determined to be a safe substance more than 400 mg / kg.

Formulation Example 1 Preparation of Tablet
