Abstract

The present invention relates to a pharmaceutical composition for preventing or treating inflammatory arthritis and, more specifically, to a pharmaceutical composition for the preventing or treating inflammatory arthritis, which comprises glutaredoxin 1 fusion protein capable of penetrating into cartilage tissue as an active ingredient.

Description

[0001] The present invention relates to pharmaceutical compositions for arthritis containing glutaredoxin 1 fusion protein,

The present invention relates to a pharmaceutical composition for the prevention and treatment of arthritis, and more particularly, to a pharmaceutical composition for preventing and treating arthritis containing GLRX1 (glutaredoxin 1) fusion protein permeable into cartilage tissue as an active ingredient.

Inflammatory arthritis is an autoimmune disease in which inflammation of the joints occurs due to various factors such as genetic and environmental factors, such as rheumatoid arthritis and ankylosing spondylitis.

Rheumatoid arthritis is a representative chronic disease in which about 1% of the population in Korea is estimated to be a patient. Although the etiology of rheumatoid arthritis varies from bacterial infection to viral infection, the precise mechanism of the disease has not yet been established. Rheumatoid arthritis is an inflammatory reaction caused by activation of synovial cells around the cartilage tissue by T lymphocytes stimulated by cytokine secretion such as tumor necrosis factor in an early stage of an onset with antigen-specific or antigen-nonspecific mechanism.

Ankylosing spondylitis is inflammatory arthritis, which is the main lesion of the spine and the cephalad joint.

Since inflammatory arthritis such as inflammatory arthritis is various, anti-inflammatory agent and anti-rheumatic agent are applied for treatment, but the therapeutic effect is incomplete.

Glutaredoxins (GLRX) is a member of the thioredoxin superfamily, a thiol / disulfide exchange catalyst, and is therefore known as a thiol transferase, and is a protein-SG which provides a reduction equivalent to ribonucleotide reductase 1 It serves as a reducing agent for mixed disulphides. In mammals, GLRX exists in two main forms. GLRX-1 is present in the cytoplasm and GLRX-2 is mainly located in the mitochondria, but also in the nucleus. Both GLRX-1 and GLRX-2 play an important role in redox regulation and protect cells against apoptosis.

In order to transfer a therapeutic drug or protein into a cell, a method of directly delivering the target protein through the cell membrane may be considered. However, proteins are very difficult to pass through cell membranes because of their size and their biochemical nature. In general, substances with a molecular weight of 600 Daltons or more are known to be almost impossible to pass through cell membranes.

In recent years, it has been found that one of the methods of protein transport is to use a PEP-1 peptide to carry a naturally occurring heterologous protein into a cell. The PEP-1 peptide consists of 21 amino acids (KETWWETWWTEW SQP KKKRKV) and has three domains (hydrophobic domain, spacer, hydrophilic domain). Until now, studies using PEP-1 peptides have revealed that when the PEP-1 peptide and the external protein are simultaneously administered to the cells, the proteins can be transported into the cells in a natural state. In addition, PEP-1 peptide has several advantages as a protein therapeutic agent compared to HIV-1 Tat protein, namely, it penetrates the protein very efficiently into cells, exhibits stability in physiological buffer solution and lack of sensitivity to serum. However, PEP-1 peptides must be administered at a constant rate with external proteins, such as green fluorescent protein (GFP), beta-galactosidase, and beta -Gal, Respectively. However, it remains unclear whether all proteins, including therapeutic proteins, can be delivered into cells by PEP-1 peptides.

In view of the above prior art, development into a formulation that allows a new protein component therapeutic agent, which has less adverse effects than conventional immunosuppressants, to penetrate into the cartilage is very important in the field of inflammatory arthritis treatment. Accordingly, the present invention aims to provide a pharmaceutical composition effective for inflammatory arthritis by using GLRX1 protein to facilitate cell infiltration.

In order to achieve the above object, the present inventors have studied to develop a protein, which is an immunosuppressive drug, as a form of enhancing cartilage penetration ability, and have found that when a GLRX1 fusion protein is treated with cartilage cells, The decrease of cytokine expression was confirmed at the protein level and the mRNA level, and the effect of treating GLRX1 fusion protein with inflammatory arthritis was confirmed, thereby completing the present invention.

The present invention relates to a pharmaceutical composition for preventing and treating arthritis, which contains a PEP-1-GLRX1 fusion protein in which the protein transport domain PEP-1 is covalently bonded to the N-terminus of a glutaredoxin 1 (GLRX1) protein.

In addition, the present invention relates to a pharmaceutical composition for preventing and treating arthritis, which comprises the glutaredoxin 1 fusion protein, wherein the fusion protein is SEQ ID NO: 4.

The pharmaceutical composition containing the glutaredoxin 1 fusion protein as an active ingredient can be formulated together with a carrier which is conventionally acceptable in the pharmaceutical field and can be formulated into an oral, external or injection form by a conventional method. Oral compositions include, for example, tablets and gelatin capsules, which may contain, in addition to the active ingredient, a diluent such as lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and / or glycine, , Magnesium stearate, stearic acid and its magnesium or calcium salt and / or polyethylene glycol) and the tablets may also contain binders such as magnesium aluminum silicate, starch paste, gelatin, methylcellulose, sodium carboxymethylcellulose and / or polyvinylpyrrolidone ), And may optionally contain a disintegrant (e.g., starch, agar, alginic acid or a sodium salt thereof) or a boiling mixture and / or an absorbent, a colorant, a flavoring agent and a sweetening agent. The injectable composition is preferably an isotonic aqueous solution or suspension, and the composition mentioned is sterilized and / or contains adjuvants such as preservatives, stabilizers, wetting or emulsifying solution accelerators, salts for controlling osmotic pressure and / or buffering agents. They may also contain other therapeutically valuable substances.

The pharmaceutical preparations thus prepared may be administered orally or parenterally, that is, intravenously, subcutaneously, intraperitoneally, or topically, as desired. The dose may be administered in a single dose of 0.01 to 100 mg / kg per day. The dosage level for a particular patient may vary depending on the patient's body weight, age, sex, health condition, time of administration, method of administration, excretion rate, severity of disease, and the like.

Furthermore, the present invention provides a pharmaceutical composition useful for the prevention and treatment of arthritis, which comprises the GLRX1 fusion protein as an active ingredient and a pharmaceutically acceptable carrier.

The present invention also provides a method for efficiently delivering a GLRX1 protein into a cell. The intracellular delivery of the GLRX1 protein molecule according to the present invention is carried out by constructing a fusion protein in which the protein transport domain including the PEP-1 peptide is covalently bonded. An example of the transport domain of the present invention is a PEP-1 peptide. However, the protein transport domain of the present invention is not limited to the PEP-1 peptide, and it is possible to produce a peptide having a function similar to the PEP-1 peptide due to partial substitution, addition or deletion of the amino acid sequence of PEP-1 It is possible to use a protein transport domain which is composed of 7 to 15 amino acids and contains 4 or more lysine or arginine and which carries the same or similar protein transport function with partial amino acid substitution therefrom The fusion protein using the protein transport domain also belongs to the scope of the present invention.

material

TPA was purchased from Sigma-Aldrich (St. Louis, MO, USA). Ni 2 + -nitrile trichlorosilicate Sepharose Superflow was purchased from Qiagen (Valencia, CA, USA). FBS and antibiotics are Gibco BRL products. Synthetic PEP-1 peptides were purchased from PEPTRON (Daejeon, Korea), and all other chemicals used top-grade products available.

PEP-1-GLRX1 fusion protein expression and purification

PEP-1 expression vector was prepared [Eum, WS et al., Free Radic. Biol. Med. 37: 1656-1669; 2004]. The human GLRX1 cDNA sequence was amplified by PCR using the sense primer 5'-CTCGAGGCAGAGCCAGACCC-3 'and the antisense primer 5'-GGATCCTCACT GGGGTTTCTCC-3'. The resulting PCR product was subcloned into the TA cloning vector and ligated into the PEP-1 expression vector to produce the PEP-1-GLRX1 protein. A vector expressing the control GLRX1 protein without PEP-1 was constructed in a similar manner. The PEP-1-GLRX1 plasmid was transformed into E. coli BL21 cells and induced with 0.5 mM IPTG (isopropyl- beta -D-thio-galactoside; Duchefa, Haarlem, Netherlands) for 6 hours at 37 ° C. The harvested cells were lysed and the PEP-1-GLRX1 fusion protein was purified with Ni 2 + -nitrilohexanoic acid sepharose superflow affinity chromatography and PD-10 chromatography (Amersham, Braunschweig, Germany). Protein concentration was determined by the Bradford method using bovine serum albumin as a standard [Bradford, MA Anal. Biochem. 72: 248-254; 1976].

Experimental Example 1: Intracellular penetration efficiency of GLRX1 fusion protein according to time and dose

1-1. Cartilage cell

Human chondrosarcoma cell line SW1353 cells, also referred to as HTB94 cells, were cultured in DMEM medium containing 10% fetal calf serum and used in the experiments.

1-2. Cell penetration efficiency by treatment time

2 μM GLRX1 fusion protein was treated with SW1353 cells for 15, 30, 45, and 60 minutes, respectively, and the intracellular penetration efficiency was confirmed by Western blotting.

As a result, as shown in Fig. 2, it was confirmed that the GLRX1 fusion protein infiltrated into SW1353 cells in a time-dependent manner. In contrast, the GLRX1 protein that did not bind the transport domain did not penetrate into the cells.

1-3. Cell Penetration Efficiency by Treatment Concentration

GLRX1 fusion proteins were treated with SWI 533 cells at concentrations of 0.25, 0.5, 1 and 2 μM, respectively, for one hour, and then the intracellular penetration efficiency was confirmed by Western blotting.

The results confirmed that the GLRX1 fusion protein infiltrated into SW1353 cells in a concentration-dependent manner, as shown in Fig. In contrast, the GLRX1 protein that did not bind the transport domain did not penetrate into the cells.

Experimental Example 2: Stability of GLRX1 fusion protein penetrated into cells

SW1353 cells were treated with 2 μM GLRX1 fusion protein for one hour. Western blotting was carried out after 1, 3, 6, 9, 12, 15, and 18 hours, respectively, for each GLRX1 fusion protein. As a result, as shown in Fig. 4, the fusion protein was stably maintained up to 15 hours.

Experimental Example  3: In inflammatory cartilage cells GLRX1 Fusion protein  by Inflammation-reducing effect

TNF-α was added to SW1353 cells to induce inflammation. After treatment of 2 μM GLRX1 fusion protein with inflammation-induced SW1353 cells, protein and mRNA expression of inflammation markers COX2 and iNOS was confirmed by Western blotting and RT-PCR. TNF-α + GLRX1 treated with 0.5 μM, lane 3: treated with 1 μM TNF-α + GLRX1, and lane 4: treated with TNF- α + GLRX1 treated with 2 μM, lane 5: TNF-α induced with inflammation, lane 6 treated with 0.5 μM TNF-α + PEP-1-GLRX1, lane 7 treated with 1 μM TNF- Lane 8: TNF-α + PEP-1-GLRX1 treated at 2 μM). The expression of COX2 and iNOS protein and mRNA expression were decreased when PEP-1-GLRX1 fusion protein was treated as compared with TNF-a treatment-induced inflammation-induced group. On the other hand, there was no change in the treatment of GLRX1 protein.

In addition, when TNF-α is added to SW1353 cells to induce inflammation, the expression of inflammatory cytokines is increased. At this time, 2 μM GLRX1 fusion protein was first treated, and inflammation was induced, and the change in the expression of inflammatory cytokines in the cells was observed by Western blotting.

The results are shown in FIG. 7 (lane 1: TNF-α inflammation induction group, lane 2: TNF-α + GLRX1 0.5 μM treatment group, lane 3: TNF- TNF-α-PEP-1-GLRX1 treated with 0.5 μM TNF-α + PEP-1-GLRX1, lane 7 treated with 1 μM TNF- : Treated with TNF-α + PEP-1-GLRX1 2 μM). Compared with TNF-α-treated inflammation-inducing group, the expression of inflammatory cytokines IL-6 and IL-1β was decreased when PEP-1-GLRX1 fusion protein was treated. On the other hand, there was no change in the treatment of GLRX1 protein.

From the above experimental results, it can be seen that, when GLRX1 fusion protein is treated on chondrocytes and cartilage tissues, GLRX1 fusion protein smoothly penetrates into cells or tissues, exhibits stability for at least 15 hours, inhibits the expression of inflammatory cytokines, And thus GLRX1 fusion proteins are expected to be available as pharmaceutical compositions for the prevention or treatment of inflammatory arthritis.
