The present invention relates to a method for purifying bee venom comprising a virus clearance process and a composition for preventing or treating inflammatory diseases using the same.

Bee venom is known to have a strong antibacterial and anti-inflammatory effect, and has been used in diseases such as arthritis and gout in folk and oriental medicine. The main component of such bee venom is melittine, which is a peptide component and is known to play a role in inflammation, antibacterial action, strong analgesic action, and immune enhancement. In order to use such bee venom as a medicine, during the purification process of bee venom, Virus clearance is a must.

In the case of animal-derived medicines, the reason why verification of the virus clearance process is essential is to experimentally demonstrate whether it is designed to effectively remove or fluoride infectious viruses that may be present in animal organs or tissues. This is because the virus does not die in the process of producing animal-derived drugs, and it is intended to eliminate the virus infection and potential risks caused by entering the body.

According to animal-derived drug virus safety evaluation guidelines, the virus clearance process can be divided into a method of physically isolating the virus and a method of reducing the infectivity by chemically or physically treating the virus. Methods for physically separating viruses include ultra-filtration, chromatography, cold ethanol fractions, etc., and methods for reducing the sensitivity of viruses by chemical or physical treatment are strong acid treatment, gamma ray irradiation, heat treatment, and S/D.

virus Clearance Fair including Bee venom Purification method

The present invention (a) preparing a bee venom solution containing bee venom; (b) first inactivating the virus by adjusting the pH of the bee venom prepared in step (a) to 2.0 to 4.0 through acid treatment; And (c) filtering the pH-adjusted bee venom in step (b) through a nano filter of 10 to 20 nm to remove the virus secondarily. .

As used herein, "viral clearance" is a concept that includes both inactivation and removal of a virus, and inactivation of the virus means that the viral infectivity is reduced by chemical or physical treatment, and removal of the virus is an animal-derived raw material. It means physically removing the virus particles that may be present in the.

On the other hand, the virus is divided according to the host of the animal-derived host, the presence or absence of the envelope, the size of the virus, and the type of nucleic acid. Examples of the virus targeted for the virus clearance are bovine viral diarrhea virus (BVDV) and zika virus (Zika virus; ZIKV), Porcine Parvovirus (PPV), and Baculovirus (BACV).

Virus name and Nature coat Size (nm) Nucleic acid Bovine Viral Diarrhea Virus
(BVDV) Toga small has exist 40-60 RNA Zika virus (ZIKV) Flavivirus mosquito has exist 40 RNA Porcine Parvovirus (PPV) Parvoviridae pig none 18-24 DNA Baculovirus (BACV) Baculoviridae silkworm has exist 280-385 DNA

As shown in Table 1, BVDV is an enveloped, medium-sized (about 40-60 nm), single-stranded RNA virus that exhibits an average degree of resistance to physico-chemical inactivation. BVDV is relatively heat resistant, susceptible to organic solvents, and unstable in acids, but stable in bases. In addition, ZIKV is spherical with a diameter of about 50 nm, and the nucleocapsid of the icosahedron is surrounded by an envelope from the endoplasmic reticulum of the host cell. Two types of proteins are expressed in the envelope: M (membrane) and E (envelope), and have a positive single-stranded RNA of about 11-kb. On the other hand, PPV is a type of non-lipid enveloped DNA virus (icosahedral) and belongs to the parvovirus family (18-24 nm in diameter). This family of parvoviruses can withstand extreme high temperatures, is stable in oily solvents, and is relatively acid-resistant. In addition, BACV can be said to be a virus unique to some invertebrates, especially insects, but this type of virus also appears in crustaceans. The virus particles are double-stranded DNA with a molecular weight (30~110)×10 ⁶ daltons. One or more nucleocapsids are enclosed encapsulated viruses, the size of which is about (200~400)×(30~90) )nm.

First, the purification method of bee venom comprising the virus clearance process according to the present invention includes the step of preparing a bee venom solution containing bee venom (step (a)).

Specifically, the bee venom solution can be prepared by completely dissolving the bee venom into 0.01 to 20.0 wt% by adding bee venom to purified water or a buffer solution. When the content of bee venom (raw material) in the bee venom solution is less than 0.01% by weight, there is a problem that the physiological activity effect by bee venom (table bee venom) corresponding to the final product is too small, and the content of bee venom in the bee venom solution is 20.0% by weight If it exceeds, there is a problem that the purification efficiency of bee venom is lowered.

In addition, by adding at least one carbon-based adsorbent selected from the group consisting of activated carbon carbon nanotubes and carbon fibers in the bee venom, additional impurities and the like can be removed.

Then, optionally, the bee venom can be filtered through a sterilizing filter of 0.1 to 1 μm under reduced pressure filtration conditions.

Next, the method for purifying bee venom comprising the virus clearance process according to the present invention is a step of first inactivating the virus by adjusting the pH of the bee venom prepared in step (a) to 2.0 to 4.0 through acid treatment [ (b) step.

Specifically, the acid treatment process does not affect the content of the main bioactive substance (melittin, phospholipase A2, etc.) of bee venom, and through this, bovine viral diarrhea virus (BVDV) or zika virus (ZIKV) It can be seen as a process for primarily inactivating the virus containing. Therefore, through the acid treatment, the pH of the bee venom can be adjusted to 2.0 to 4.0, and the pH is preferably adjusted to 2.5 to 3.5, but is not limited thereto.

More specifically, the acid treatment may be performed by treating a strong acid at a concentration of 0.1 to 1.0 M for 1 to 20 hours. The strong acid may include one or more selected from the group consisting of hydrochloric acid, acetic acid, sulfuric acid, nitric acid, and hydrofluoric acid. When the concentration of the strong acid is less than 0.1 M, there is a problem that too much amount of strong acid is required in the acid treatment process. , If the concentration of the strong acid exceeds 1.0 M, there is a fear that it affects the main bioactive substances of bee venom. In addition, the acid treatment is preferably treated for 1 to 20 hours, more preferably for 1 to 6 hours, but is not limited thereto. If the acid treatment time is too short, there is a problem that the virus inactivation is not sufficiently performed, and when the acid treatment time is too long, there is a problem that the main physiologically active substance is affected and the pharmacological activity effect is reduced.

The pH-adjusted bee venom solution may maintain the melittin content at 40% by weight or more, and preferably 45% by weight or more, but is not limited thereto.

Subsequently, the pH of the pH-adjusted bee venom can be corrected to 4.5 to 5.5 through a base treatment. The base treatment may be performed by treating a base such as sodium hydroxide at a concentration of 0.1 to 1.0 M. If the concentration of the base is less than 0.1 M, there is a problem that too much base is required for the base treatment process, and if the concentration of the base exceeds 1.0 M, there is a fear of affecting the main bioactive substance of bee venom. have.

Next, the method of clearing the virus according to the present invention comprises the step of filtering the pH-adjusted bee venom in step (b) through a nano filter of 10 to 20 nm to remove the virus secondarily ((c) step ].

Specifically, the nano-filter process, without affecting the content of the main physiologically active substances (melittin, phospholipase A2, apamine, etc.) of bee venom, through this, through small virus diarrhea virus (BVDV), zika virus ( ZIKV), porcine parvovirus (PPV) and barbell circovirus (BACV) can be viewed as a process for secondary removal of viruses containing one or more selected from the group consisting of. On the other hand, when using an organic solvent instead of the nano-filter process, not only the yield is significantly lowered, there is a problem that the pharmacologically active effect is also significantly lowered.

In particular, the pores of the nano-filter used in the nano-filter process are maintained at 10 to 20 nm, so that a small-sized virus (eg, small-virus diarrhea virus (BVDV), zika virus (ZIKV), and porcine parvovirus (PPV), etc. ) Can be effectively removed.

The material of the nano filter may be variously selected, but polyethersulfone (PES) is most preferable in terms of filtration rate, but is not limited thereto.

The bee venom filtered in the step (b) may have a filtration rate of 600 mL/hr or higher or a yield of 60% or higher while maintaining both the melittin and protein content at 45% by weight or more.

Therefore, before using the nano-filter, optionally, the step of filtering the pH-adjusted bee venom in step (b) through a membrane filter of 0.05 to 1 μm may further include the step of removing the protein in advance. At this time, the membrane filter may have a molecular weight cut-off of 200 kDa.

Then, filtering the bee venom filtered in the step (c) through a 0.1 ~ 1 ㎛ antibacterial filter [(d) step]; And lyophilizing the filtered bee venom in step (d) (step (e)). At this time, the freeze drying (FD) rapidly freezes the raw materials at a temperature of -40 to -120°C, and then, in a freeze dryer with a vacuum degree of 0.1 Torr-0.9 Torr, stepwise low temperature heat is applied to solid ice. By sublimation, it is possible to obtain a dry product of higher quality than ordinary drying. More preferably, freeze-drying may be performed at a temperature of -80 to -100°C and a vacuum of 0.2 to 0.5 Torr.

Experimental Example 2: Acid treatment Pharmacological activity effect by process optimization

(One) Raw264 .7 Cytotoxicity Assessment

The macrophage cell line, Raw264.7 cells, was purchased from the Korean cell line bank (Cat No. KCLB40071) and used for Dulbecco's modified with 10% Fetal bovine serum (FBS, Hyclone) and 100 IU/ml penicillin and 100 μg/ml streptomycin. The experiment was performed by culturing in an incubation of 5% CO ₂ and 37° C. using Eagle medium (DMEM, Hyclone) medium.

After incubating RAW264.7 macrophages, bee venom was added at each concentration of 4 at pH 3 in Example 2, and then MTT (methylthiazol tetrazolium bromide, Sigma Aldrich) was performed to confirm cell viability. Cells were seeded in 24 well plates (BD, Falcon) in appropriate amounts (5X10 ⁴ /well), samples were processed for each concentration, and cell viability was confirmed after 48 hours incubation at 37°C incubator. After reacting with MTT solution (3-(4,5-dimethylthiazol-2-yl) -2,5 -diphenyl tetrasodium bromide) for 4 hours, 400 μl of DMSO was added to dissolve the insoluble formazan crystals to dissolve 570 nm wavelength. Absorbance was measured with an ELISA reader (TECAN, Infinite M200 pro), and the results are shown in Table 3 and FIG. 2.

As shown in Table 3, regardless of the acid treatment time, the bee venom or bee venom (raw material) prepared in Example 2 was confirmed to show non-toxicity up to 5 ug/ml.

(2) Nitric Oxide release measurement

To measure the Nitric Oxide release, Raw264.7 cells, macrophages, were dispensed and cultured in a 48 well plate to be 2.5x10 ⁴ /well. Subsequently, the Nitric Oixde inhibition rate of bee venom was treated according to the concentration desired to be confirmed, followed by incubation for 24 hours, and then treated with LPS at a concentration of 1 μg/mL in each well, followed by incubation for 24 hours. After incubation, 100 μL of the culture supernatant was taken, the same amount of Griess reagent was added and left for 15 minutes, and absorbance was measured with an ELISA reader (TECAN, Infinite M200 pro) at a wavelength of 540 nm, and the results are shown in Table 3. .

At this time, among the samples used, the control group is prepared by performing a freeze-drying process without acid treatment of bee venom at this time to compare the Nitric Oxide release activity before and after the acid treatment process of purified bee venom.

As shown in Table 3, in the control group, pH3 of Example 2, by treatment time, 3 hours, 6 hours, and 15 hours, the purified bee venom samples were confirmed that all NO inhibitory levels showed a boiling value. This means that the acid treatment process of the purified bee venom does not affect the Nitric Oxide release activity of the purified bee venom.

(3) inflammatory TNF -alpha measurement

To measure TNF-alpha, the macrophages Raw264.7 cells were dispensed and cultured in a 48 well plate to be 2.5x10 ⁴ /well. Subsequently, the TNF-alpha of bee venom was treated according to the desired concentration, and cultured for 24 hours, and then LPS was treated at a concentration of 1 μg/mL in each well and cultured for 24 hours. Then, the supernatant was taken and measured using a Mouse TNF-alpha Quantikine ELISA Kit (R&D Systems; MTA00B). In addition, for cell quantification, the supernatant was removed and reacted with MTT solution (3-(4,5-dimethylthiazol -2-yl) -2,5 -diphenyl tetrasodium bromide) for 4 hours, followed by 300 µl of DMSO. The absorbance was measured by dissolving inma insoluble inmazan crystals at a wavelength of 570 nm with an ELISA reader (TECAN, Infinite M200 pro), and the results are shown in Table 3.

At this time, among the samples used, the control group is prepared by comparing the TNF-alpha activity before and after the acid treatment process by preparing the bee venom through an lyophilization process without acid treatment.

As shown in Table 3, when the acid treatment time was within 6 hours, the TNF-alpha inhibitory ability was compared to the contol group that had not undergone acid treatment and had undergone a lyophilization process, but when the acid treatment time was 15 hours, the control group In comparison, it was confirmed that the TNF-alpha inhibitory activity was lowered. This means that the TNF-alpha activity of purified bee venom is not affected when the acid treatment process is set to within 6 hours during the process of bee venom.

Example 4: Nano filter ( PES ) Use

The bee venom was added to purified water to completely dissolve the bee venom to 5.0% by weight to prepare bee venom. At this time, activated carbon can be used to remove foreign substances and odors. Thereafter, the bee venom was filtered through a 0.22 μm pore removal filter under reduced pressure filtration conditions. Then, the virus was first inactivated by adjusting the pH of the bee venom to 3 by treating hydrochloric acid at a concentration of 0.2 M for 3 hours, and then treating the sodium hydroxide at a concentration of 0.2 M to adjust the pH of the bee venom to 5 . At this time, the pH may be corrected through an ultrafiltration (UF) process instead of sodium hydroxide. Subsequently, under reduced pressure filtration conditions, the bee venom is pre-filtered through a membrane filter of 0.1 μm pores, and then the bee venom is made through a 20 nm pore polyethersulfone (PES) material nano filter (Virosart CPV, Sartorius). Was filtered. Specifically, after the nano filter was attached to the filtration device, 10 ml of ultrapure water was added to the sample container, and pressure was applied using nitrogen gas to remove air bubbles. After removing the bubbles in the nano-filter pores, the bee venom solution was added to the sample container and filtered using nitrogen gas under pressure. At this time, the pressure was maintained at 2.0 to 3.0 bar. Thereafter, the bee venom solution was filtered again through a 0.22 μm pore-removing filter under reduced pressure filtration conditions, and then rapidly frozen at a temperature of -80° C. or lower and freeze-dried in a vacuum of 0.5 torr or less to obtain bee venom in powder form. It was prepared.

At this time, the control group was prepared by freeze-drying without acid treatment and nano-filtering.

Example 5: Nano filter( PVDF ) Use

A bee venom was prepared in the same manner as in Example 4, except that a polyethersulfone (PES) material nano filter (Virosart CPV, Sartorius) was used instead of a polyvinylidene fluoride (PVDF) material nano filter.

Experimental Example 3: Optimization of nano filter process (1)

Protein content and filtration rate of bee venom prepared in Examples 4 to 5 were analyzed by electrophoresis and HPLC, and the results are shown in Table 4, FIGS. 3(a) and 3(b).

division Melittin content Protein content Filtration rate Control 63.90% 61.28% - Example 4 (PES) 61.82% 60.94% 700mL /1hr Example 5 (PVDF) 63.04% 60.04% 315mL /1hr

As shown in Table 4, regardless of the material of the nano-filter, the melittin content and protein content of bee venom after the nano-filter process are found to be similar, so the nano-filter process does not affect the main component content of bee venom. In particular, in the case of the polyether sulfone (PES) material as in Example 4, it is confirmed that the filtration rate is superior to the polyvinylidene fluoride (PVDF) material as in Example 5.

Comparative example One: Organic solvent Use

The bee venom was added to purified water to completely dissolve the bee venom to 5.0% by weight to prepare bee venom. First, the bee venom was filtered through a 0.22 μm pore removal filter under reduced pressure filtration conditions. Then, the virus was first inactivated by adjusting the pH of the bee venom to 3 by treating hydrochloric acid at a concentration of 0.2 M for 3 hours, and then treating the sodium hydroxide at a concentration of 0.2 M to adjust the pH of the bee venom to 5 . Subsequently, 70% ethanol was added to the bee venom and precipitated. After standing for 1 hour at room temperature, purified water was added and stirred. Then, ethanol was removed by filtration and concentration through an ultrafiltration membrane of 3 kDa or less.
