Description

Technical Field

[0001] The present application relates to a peptide having protective activity against cell damage caused by particulate matter, and the use of the peptide. Background Art

[0002] Particulate matter refers to small, invisible particles of dust. Particulate matter is an air pollutant that includes sulfur dioxide, nitrogen oxides, lead, ozone, carbon monoxide, etc., which is produced in cars, factories, cooking processes, etc. and suspended in the atmosphere for a long time. Particles with a diameter of less than 50μm suspended in the atmosphere are called total suspended particles (TSP), and particles smaller than 10μm in these TSP are usually defined as particulate matter. Particulate matter is divided according to the diameter of the particles. Particles with a diameter of less than 10μm are named PM10, and particles with a diameter of less than 2.5μm are named PM2.5, also known as "fine particles" or "ultrafine particles."

[0003] Particulate matter contains carbon, organic hydrocarbons, nitrates, sulfates and harmful metal components, and is known to directly induce or aggravate respiratory diseases, cardiovascular diseases, eye diseases, cancer, skin diseases, headaches, etc. In addition, since the particle size of particulate matter is about one-fifth of the pores of the skin, when particulate matter penetrates into the skin, the protective film function of the outer layer of the skin is damaged and the skin becomes sensitive to irritation.

[0004] Polycyclic aromatic hydrocarbons (PAH) contained in particulate matter enter the skin through the hair follicles in the skin, increasing melanocytes and pigment spots, reducing collagen synthesis, and increasing collagen decomposition, thereby causing wrinkles, reducing skin elasticity and promoting skin aging. PAHs can penetrate into cells, bind to aromatic hydrocarbon receptors (AHR) that have already penetrated into cells, and be transported to the cell nucleus. The AHR transported to the cell nucleus forms a complex AHR / ARNT with the AHR nuclear transporter (ARNT), and the complex "AHR / ARNT" binds to the AHR response element (AHRE) on DNA, the dinucleotide kinase (DNT), and the aryl hydrocarbon receptor (AHR) on DNA. The DRE and XRE sequences combine to produce reactive oxygen species (ROS), or toxic substances are produced through enzymes such as CYP1A1, CYP1A2 and CYP1B1, thereby inducing cell damage and increasing the expression of various inflammatory mediators, causing dermatitis, pigment hyperplasia (chloasma, freckles, etc.) and wrinkles on the skin. Among them, microphthalmia-related transcription factor (Mitf) is a transcription factor related to melanin synthesis, and matrix metalloproteinase (MMP) is an enzyme related to wrinkle formation.

[0019] According to yet another aspect of the present invention, there is provided a pharmaceutical composition for treating or preventing a disease caused by particulate matter, the pharmaceutical composition comprising a peptide consisting of the amino acid sequence of SEQ ID NO: 1 as an active ingredient.

[0020] Hereinafter, the present invention will be described in detail.

[0021] 1. Peptides and activity

[0022] According to one aspect of the present invention, a peptide consisting of the amino acid sequence of SEQ ID NO: 1 is provided.

[0023] As used herein, the term "peptide" refers to a linear molecule formed by amino acid residues linked together by peptide bonds.

[0024] The peptide of the present invention consisting of the amino acid sequence of SEQ ID NO: 1 can be used without modification, but on the other hand, the peptide can be a variant or fragment of amino acids with a different sequence formed by deletion, insertion, substitution or a combination thereof of amino acid residues within a range that does not affect the original activity of the peptide (e.g., the activity of protecting against cell damage caused by particulate matter).

[0025] The peptide of the present invention can be modified by phosphorylation, sulfation, acryloylation, glycosylation, methylation, farnesylation, etc. within the range that does not change the activity of the peptide.

[0026] The peptides of the present invention include peptides and variants thereof or active fragments thereof comprising an amino acid sequence substantially identical to the amino acid sequence of a peptide consisting of the amino acid sequence of SEQ ID NO: 1. A peptide comprising a substantially identical amino acid sequence refers to an amino acid sequence comprising an amino acid sequence having at least 75%, such as at least 80%, at least 90% or at least 95% sequence identity with the amino acid sequence of SEQ ID NO: 1. The peptide may also include additional sequences, such as targeting sequences, tags, labeled residues, or amino acids prepared for a specific purpose to increase the half-life or stability of the peptide.

[0027] The peptides of the present invention may have induced N-terminal and / or C-terminal modifications to select certain parts of the amino acid sequence and increase their activity. The stability of the peptides of the present invention can be significantly improved by N-terminal and / or C-terminal modifications, for example, when the peptide is administered in vivo, the half-life of the peptide can be extended. The term "stability" of a peptide refers not only to the in vivo stability for protecting the peptides of the present invention from in vivo protease attacks, but also to storage stability (e.g., storage stability at room temperature).

[0028] The N-terminal modification may be the binding of a protecting group selected from the group consisting of acetyl, fluorenylmethoxycarbonyl, formyl, palmitoyl, myristoyl, stearoyl and polyethylene glycol (PEG) to the N-terminal of the peptide.

[0029] The C-terminal modification may be the binding of a hydroxyl group (-OH), an amino group (-NH2), an azido group (-NHNH2), etc. to the C-terminal of the peptide, but is not limited thereto.

[0030] The peptides of the present invention can be prepared by various methods widely known in the art to which the present invention belongs. For example, the peptides of the present invention can be prepared using chemical synthesis methods known in the art, particularly solid phase synthesis techniques (Merrifield, J. Amer. Chem. Soc. 85: 2149-54 (1963); Stewart, et al., Solid Phase Peptide Synthesis, 2nd. ed., Pierce Chem. Co.: Rockford, 111 (1984)) or liquid phase synthesis techniques (US Patent No. 5,516,891).

[0031] The peptides of the present invention can effectively prevent cell damage caused by particulate matter.

[0032] Polycyclic aromatic hydrocarbons (PAH) contained in particulate matter can penetrate into cells, and the PAHs that penetrate into cells will bind to the aryl hydrocarbon receptor (AHR) and be transported to the cell nucleus. The AHR transported into the cell nucleus forms a complex AHR / ARNT with the AHR nuclear translocator (ARNT), and the complex "AHR / ARNT" binds to the AHR response element (AHRE), dinucleotide kinase (DNT) and mitochondria on DNA. The DRE and XRE sequences bind to the cytotoxic factor response element (DRE) and the xenobiotic response element (XRE) to generate reactive oxygen species (ROS) or increase the expression or activity of enzymes (such as CYP1A1, CYP1A2, and CYP1B1), thereby producing toxic substances that induce cell damage and increase the expression of various inflammatory mediators.

[0033] The peptide of the present invention significantly inhibits the nuclear translocation of the aryl hydrocarbon receptor (AHR) and the thereby increased cytochrome P450 activity in cells due to contact with particulate matter, thereby being able to prevent cell damage caused by particulate matter.

[0075] Preparation Example 1: Preparation of peptide

[0076] The peptides having the amino acid sequence of SEQ ID NO: 1 shown in Table 1 below were synthesized using an automatic peptide synthesizer (Liberty, CEM, USA), and the synthesized peptides were purified by C18 reverse phase high performance liquid chromatography (HPLC) (U-3000, Thermo Fisher Scientific, USA).

[0079] Experimental Example 1: Nuclear translocation assay of AHR

[0080] Polycyclic aromatic hydrocarbons (PAHs) present in particulate matter act as ligands for AHR, thereby promoting nuclear translocation of AHR when PAHs penetrate into cells and bind to AHR. To confirm the effect of the synthesized peptide in inhibiting cell damage caused by particulate matter, experiments were performed to demonstrate whether the peptide inhibits nuclear translocation of AHR observed upon ligand-AHR binding after treating cells with particulate matter.

[0081] Human keratinocytes HaCaT cells were cultured at 5 x 10 5 The cells were seeded into 6-well plates at a density of 10 cells / well. After overnight culture, the medium was replaced with serum-free medium. The keratinocytes HaCaT were pretreated with the synthetic peptides at each concentration (20 μM, 100 μM, and 200 μM) for 1 hour. Then, 50 μg / cm 2The cells were treated with urban particulate matter (Sigma, NIST1648A) for 1 hour. After collecting keratinocytes, nuclear extracts were prepared and subjected to Western blotting. Western blotting was performed using anti-AHR antibodies (Cell Signaling Technology) according to protocols known in the art.

[0082] As a result of the experiment, Figure 2 The results of the Western blot shown show that the nuclear translocation of AHR in cells treated with particles (NC) increased rapidly compared to control cells not treated with particles (Con). In addition, it was confirmed that the nuclear translocation level of AHR increased by particle treatment was significantly reduced in cells treated with the peptide of the amino acid sequence of SEQ ID NO: 1.

[0083] Experimental Example 2: Analysis of Cytochrome P450 Activity

[0084] When polycyclic aromatic hydrocarbons (PAH) present in particulate matter penetrate into cells and bind to AHR, it promotes nuclear translocation of AHR. It is known that AHR translocated to the nucleus forms a complex AHR / ARNT with the AHR nuclear translocator (ARNT), which acts as a transcription factor to promote the expression of cytochrome P450 (CYP). In order to confirm the effect of the synthesized peptide in inhibiting cell damage caused by particulate matter, an experiment was conducted to confirm whether the peptide inhibits the activity of cytochrome P450 after treating cells with particulate matter.

[0085] First, human keratinocytes HaCaT cells were cultured at 1x 10 4 The cells were seeded into 96-well plates at a density of 10 cells / well. After overnight culture, the medium was replaced with serum-free medium. The keratinocytes HaCaT were pretreated with the synthetic peptides at each concentration (20 μM, 100 μM, and 200 μM) for 1 hour. Then, 50 μg / cm 2 The cells were treated with urban particulate matter (Sigma, NIST1648A) for 24 hours. After the keratinocytes were collected, the P450-Glo TM The activity of cytochrome P450 was measured using an assay kit (Promega).

[0086] As a result of the experiment, Figure 3The results of the measurement of cytochrome P450 activity shown in the figure show that the cytochrome P450 activity in the cells treated with particles (NC) increased rapidly compared to the control cells (Con) not treated with particles. In addition, it was confirmed that the activity of cytochrome P450 increased by the treatment with particles decreased in the cells treated with the peptide of the amino acid sequence of SEQ ID NO: 1. In addition, the increase in cytochrome P450 activity caused by the treatment with particles decreased in a manner dependent on the concentration of the treated peptide when the cells were treated with the peptide.

[0087] In addition, to confirm whether the peptide can inhibit respiratory damage caused by particulate matter, a cytochrome P450 activity assay experiment was performed on human alveolar epithelial cells A549 cells.

[0088] First, human alveolar epithelial A549 cells were cultured at 1.2 x 10 4 The cells were seeded into 96-well plates at a density of 10 cells / well. After overnight culture, the medium was replaced with serum-free medium. Alveolar epithelial A549 cells were pretreated with the synthetic peptides at each concentration (20 μM, 100 μM, and 200 μM) for 1 hour. Then, 50 μg / cm 2 The cells were treated with urban particulate matter (Sigma, NIST1648A) for 24 hours. After the treated cells were collected, the P450-Glo TM The activity of cytochrome P450 was measured using an assay kit (Promega).

[0089] As a result of the experiment, Figure 4 From the results of the measurement of cytochrome P450 activity shown in , it can be seen that the cytochrome P450 activity in the cells treated with particles (NC) increased rapidly compared to the control cells (Con) not treated with particles, and it was confirmed that the cytochrome P450 activity increased by the particle treatment decreased in the cells treated with the peptide of the amino acid sequence of SEQ ID NO: 1. In addition, the increase in cytochrome P450 activity caused by the particle treatment decreased in a manner dependent on the treatment peptide concentration during the peptide treatment.
