Description

[0001] The present invention relates to a cosmetic composition containing a fusion protein of insulin-like growth factor-1 (IGF-1)

The present invention relates to a cosmetic composition for improving skin comprising a fusion protein of insulin-like growth factor-1 (IGF-1). More specifically, the present invention relates to a skin permeation enhancing peptide comprising a fusion protein in which IGF- A cosmetic composition for improving skin comprising the fusion protein, a cosmetic composition for improving hair loss, and a quasi-drug composition containing the fusion protein.

Drugs that pass through the skin are used in analgesic patches, smoking cessation patches, pregnancy regulators, and the like due to their ease of use and have the purpose of delivering them to the systemic circulation through the skin. At the same time, it may have the purpose of delivering it to the skin's own organs such as atopic treatments, whitening, and cosmetics for improving wrinkles. Despite the goal of having such convenience and functionality, it is difficult to deliver drugs due to the structure of the skin, which can be understood by looking at the structure of the skin. The stratum corneum of the skin, which is composed of about 10-15 layers of corneocytes, has a brick structure composed of keratin-rich keratinocytes, and a ceramide, a fatty acid, It has a mortar structure filled with lipids such as wax and has a thickness of about 10 to 45 um. This structure prevents internal moisture loss and prevents external intrusion. Thus, the material permeability is very low in accordance with its role. Only low-molecular-weight components below 500 Da are delivered into the skin by the diffusion method (Exp. Dermatol., 2000, 9, 165-9). This is done through the water-soluble structure between the lipid layer in the cell and the lipid layer in the mortar structure, and the substance permeability is highly dependent on the nature of the drug (Current Drug Delivery, 2005, 2, 23-3). In addition to passing directly through the surface of the skin, it can also be delivered using structures such as sweat glands, pores, and sebaceous glands of the skin.

For this reason, research has been actively conducted to develop a method that can permeate the skin regardless of the size or nature of the molecule, and can evenly transmit the whole skin.

 For example, U.S. Patent No. 7,659,252 discloses skin permeable peptides that can be used to treat skin diseases and promote skin penetration of pharmaceutical active agents. The peptide not only exhibits excellent skin permeability but also can be used as a carrier for transdermal delivery of other drugs. However, since the peptide is consumed through the circulatory system in the body after permeating through the skin, in the case of a drug targeting the skin It has a disadvantage that it can not exert any significant effect.

This disadvantage is known as a cause of promoting collagen synthesis, endothelial cell growth or hyaluronic acid production, and various effective ingredients showing wrinkle-reducing effects are not normally absorbed through the skin. Therefore, a method for promoting absorption of the active ingredient has been developed Research was actively pursued. For example, Korean Patent Registration No. 1054519 discloses a human growth hormone-derived peptide and a composition containing the human growth hormone-derived peptide, which are superior in stability and skin permeability to natural human growth hormone. In Korean Patent No. 1104223, 10-derived peptides having the same functions as those of natural IL-10 and having excellent stability and skin permeability as compared with natural IL-10, and compositions comprising the same. However, these peptides are merely functional, It can not be used as a delivery carrier for other drugs. This disadvantage has been analyzed as suggesting that the property of excellent skin permeability can not be used for drug delivery. Therefore, it has been required to develop a new substance including two properties that not only have excellent skin permeability but also improve skin retention, There is no report on the research results.

Under these circumstances, the inventors of the present invention have made extensive efforts to develop a novel substance that has both excellent skin permeability and excellent skin durability. As a result, they have found that they can be used as a carrier for transdermal delivery of drugs, The inventors of the present invention have developed a peptide for promoting skin permeation and confirmed that the fusion protein obtained by fusing IGF-1 to the peptide for promoting skin permeation exhibits both excellent skin permeability and skin retention properties.

Hybridization requires that two nucleic acids have a complementary sequence, although mismatches between bases are possible, depending on the severity of hybridization. The term " complementary " is used to describe the relationship between nucleotide bases capable of hybridizing with each other. For example, with respect to DNA, adenosine is complementary to thymine and cytosine is complementary to guanine. Thus, the present invention may also include substantially similar nucleic acid sequences as well as isolated nucleic acid fragments complementary to the entire sequence.

Specifically, polynucleotides having homology can be detected using hybridization conditions including the hybridization step at a Tm value of 55 ° C and using the conditions described above.

 As used herein, the term "homology" refers to the percentage of identity between two polynucleotide or polypeptide moieties. Means the degree of agreement with a given amino acid sequence or base sequence and can be expressed as a percentage. In the present specification, its homologous sequence having the same or similar activity as a given amino acid sequence or base sequence is referred to as "% homology ". The homology between sequences from one moiety to another may be determined by known techniques. For example, standard software for calculating parameters such as score, identity and similarity, specifically BLAST 2.0, or by sequential hybridization experiments under defined stringent conditions, And the appropriate hybridization conditions to be defined are within the skill of the art and can be determined by methods well known to those skilled in the art (for example, J. Sambrook et al., Molecular Cloning, A Laboratory Manual, 2nd Edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York, 1989; FM Ausubel et al., Current Protocols in Molecular Biology, John Wiley & Sons, Inc., New York).

The regulatory sequence may include a promoter capable of initiating transcription, any operator sequence for regulating such transcription, a sequence encoding a suitable mRNA ribosome binding site, and a sequence controlling the termination of transcription and translation. The vector may be transcribed into an appropriate host cell and then cloned or functioned independently of the host genome and integrated into the genome itself.

The vector used in the present invention is not particularly limited as long as it is replicable in the host cell, and any vector known in the art can be used. Examples of commonly used vectors include plasmids, cosmids, viruses and bacteriophages in their natural or recombinant state. For example, pWE15, M13, MBL3, MBL4, IXII, ASHII, APII, t10, t11, Charon4A and Charon21A can be used as the phage vector or cosmid vector, and pBR, pUC, pBluescriptII , pGEM-based, pTZ-based, pCL-based, pET-based, and the like.

For example, a polynucleotide encoding a desired polypeptide in a chromosome can be replaced with a mutated polynucleotide through a vector for intracellular chromosome insertion. The insertion of the polynucleotide into the chromosome can be accomplished by any method known in the art, for example, homologous recombination, but is not limited thereto.

The term "transformation" in the present invention means introducing a vector comprising a polynucleotide encoding a target polypeptide into a host cell so that the polynucleotide encoded by the polynucleotide can be expressed in the host cell. Transformed polynucleotides may include all of these, whether inserted into the chromosome of the host cell or located outside the chromosome, provided that the polynucleotide can be expressed in the host cell. For example, electroporation, calcium phosphate (CaPO4) precipitation, calcium chloride (CaCl2) precipitation, microinjection, polyethylene glycol (PEG) method, DEAE-dextran method, cationic liposome method, -DMSO method, and the like. The polynucleotide also includes DNA and RNA encoding the target polypeptide. The polynucleotide may be introduced in any form as far as it is capable of being introduced into a host cell and expressed. For example, the polynucleotide may be introduced into a host cell in the form of an expression cassette, which is a gene construct containing all the elements necessary for its expression. The expression cassette can typically include a promoter operably linked to the polynucleotide, a transcription termination signal, a ribosome binding site, and a translation termination signal. The expression cassette may be in the form of an expression vector capable of self-replication. Also, the polynucleotide may be introduced into the host cell in its own form and operatively linked to the sequence necessary for expression in the host cell, but is not limited thereto.

The term " keratinocyte " refers to a cell having keratinocytic ability in epidermal cells. The keratinocytes are formed through mitosis in the basal layer of the epidermis (embryonic layer), then move to the surface layer, differentiating, and falling off the surface constantly. In this process, the nucleated cells are transformed into keratinocytes, which are dead cells with no nucleus in the nucleus. The keratinocytes account for about 80 to 90% of the epidermal cells and have a special function of producing keratin, which forms structural proteins of the hair and nails as well as the stratum corneum of the epidermis. The keratinocytes constitute the stratum corneum and inhibit the evaporation of water at the outermost part of the skin, thereby affecting the maintenance of skin elasticity and alleviation of skin wrinkles.

According to one embodiment, the effect of the fusion protein on the keratinocyte growth was confirmed in order to confirm the effect of the skin elasticity and the skin wrinkle improvement of the present invention. IGF-1 and fusion protein (T-IGF-1) were added to keratinocytes and cultured. As a result, it was confirmed that T-IGF-1 had a keratinocyte growth function equivalent to that of IGF-1 (Table 1).

Effect of fusion protein on keratinocyte growth Treated protein Generation level (%) Control group 100 ± 12 IGF-1 250 ± 20 T-IGF-1 235 ± 15

As shown in Table 1, it was confirmed that T-IGF-1, in which IGF-1 was fused with a peptide for promoting skin permeation, had the same level of improving skin wrinkle elasticity as IGF-1.

Example  3-2: Follicular stem cell proliferation  Efficacy verification

The effect of T-IGF-1 synthesized in Example 2 on IGF-1 on skin cell proliferation was examined.

Specifically, dermal papilla cells were inoculated into 96-well plates and cultured for 24 hours to obtain cultures representing 6,000 cells per well. The cultures were washed with PBS and then cultured in serum-free DMEM medium for 1 day. After washing with PBS, the cells were cultured in serum-free DMEM medium containing 1 ng / ml of T-IGF-1 or IGF-1 for 1 day. The culture was obtained, and the difference in the amount of cell proliferation was quantitatively analyzed using Cell Counter Kit-8 (Dojindo). As a control, T-IGF-1 or IGF-1-free serum-free DMEM medium was used (Table 2).

Effects of Fusion Proteins on Follicular Stem Cell Proliferation Treated protein Growth level (%) Control group 100 ± 15 IGF-1 440 ± 45 T-IGF-1 320 ± 40

As shown in Table 3, it was confirmed that T-IGF-1, in which IGF-1 is fused with a skin permeation enhancing peptide, has cell proliferation efficiency equivalent to that of IGF-1.

Thus, it can be seen that even when the peptide for promoting skin permeation is fused to IGF-1, it has the effect of improving the hair loss of IGF-1.

Example  3-3: Verification of skin permeability

The skin permeability was verified by comparing the fusion protein T-IGF-1 synthesized in Example 2 with IGF-1.

Specifically, pig skin (0.7 mm thick, Medikinetics) was mounted between the top and bottom of a Franz glass cell (Standard diameter 9 mm, Receiver 5 ml, Permegear), and TBS (50 mM Tris pH 7.5, 150 mM NaCl) was prepared. To the top of the glass cell, 500 μl of TBS was added to the donor chamber, and 5 ml of TBS was added to the bottom of the glass cell (receiver chamber). Then, 2 μg of IGF-1 or T-IGF-1 was added to the top and allowed to react for 16 hours. The concentration of IGF-1 or T-IGF-1 present at the lower end was measured by ELISA kit (R & D Systems) , And the relative content of T-IGF-1 to the content of IGF-1 was calculated as a permeation amount (Table 3).

Skin permeability of fusion protein Treated protein Permeability (%) IGF-1 100 ± 14 T-IGF-1 280 ± 18

As shown in Table 3, it was confirmed that the skin permeability of T-IGF-1 was about 3 times higher than that of IGF-1.

Thus, it can be seen that the skin permeability is remarkably increased when the fusion protein of the present invention is used.

Example  3-4: Verification of skin persistence

Skin fusion was verified by comparing the fusion protein T-IGF-1 synthesized in Example 2 with IGF-1.

Specifically, the pig skin remaining after the experiment in Example 3-4 was recovered, and then the liquid nitrogen was frozen and pulverized. The content of IGF-1 or T-IGF-1 contained therein was measured using an ELISA kit (R & D Systems) And analyzed quantitatively. In addition, the relative amount of the amount of T-IGF-1 to the content of IGF-1 was calculated as the residual amount (Table 4).

Skin persistence of fusion protein Treated protein Residual amount (%) IGF-1 100 ± 28 T-IGF-1 9,100 ± 650

As shown in Table 4, it was confirmed that T-IGF-1 increased the skin retention by about 100 times as compared with IGF-1.

Thus, it can be seen that skin retention remarkably increases when the fusion protein of the present invention is used.
