Abstract
Description
Technical Field
[0001] The present invention relates to peptides having the activities of promoting hair growth and inhibiting hair loss and uses thereof. Background Art
[0002] Alopecia is a phenomenon of excessive hair shedding due to the resting phase becoming longer than normal or the number of hair follicles in the resting phase increasing, and means that excessive hair shedding occurs due to stress, nutritional deficiency, local blood flow disorders, hormones, genetic factors, etc., and it cannot be restored.
[0003] As a therapeutic agent for hair loss, 5α-reductase inhibitors convert the male hormone testosterone into the androgenic sex hormone dihydrotestosterone (DHT), for example, drugs such as finasteride or dutasteride have been developed and approved for commercial sale, and minoxidil, a drug that promotes hair growth by stimulating hair follicles and increasing blood flow, has also been approved and used.
[0004] However, for 5α-reductase inhibitors, side effects such as sexual dysfunction, depression, anxiety, and breast enlargement are reported to occur relatively frequently; and for minoxidil, side effects such as electrocardiogram abnormalities, tachycardia, and endocarditis are reported to occur; in addition, it is reported that hair loss begins again once minoxidil administration is stopped.
[0005] Peptides have high biocompatibility and, when used as a single active ingredient in medicine or cosmetics, have fewer side effects than extracts including various ingredients. After inhibiting local hair loss, these peptides are easily decomposed and cleared by proteases in the body; therefore, there are fewer concerns about the side effects of these peptide drugs than existing therapeutic agents.
[0006] PCT International Patent Application WO 2005-082395 discloses a peptide having a hair growth promoting effect by promoting the progression from the telogen phase to the growth phase in the hair growth cycle, and Korean Patent No. 10-2387764 discloses a peptide derivative in the form of a dimer that promotes the proliferation of hair follicle cells.

Then, the culture medium was replaced with serum-free mesenchymal stem cell culture medium and cultured for another 24 hours. The cultured cell cultures were treated with 10 μM, 50 μM and 100 μM of the peptide prepared in the above preparation example 1, respectively, and treated with 10 ng / mL of recombinant human Wnt-3a (rhWnt-3a protein, R&D Systems (MN, USA)) as a positive control, and treated with no substance as a negative control (con), and these cultures were each cultured for another 24 hours at 37 ° C. After washing each culture with PBS, RNA was isolated by treating with 300 μL of eaay blue (Intron, South Korea). The isolated RNA was quantified using Nanodrop, and then cDNA synthesis was performed using a cDNA synthesis kit (Enzynomics, South Korea). Then, PCR reaction was performed using a PCR premix (Enzynomics, South Korea) and the primers shown in Table 2 below. The PCR products were electrophoresed on 1.5% agarose gel, and the bands were detected using the Bio-Rad gel imaging system.
[0109] [Table 2]
[0110]
[0111] The experimental results are as follows Figure 3a and Figure 3b As shown, it was confirmed that when HHFDPCs were treated with the peptide of Preparation Example 1 above at 10 μM, 50 μM and 100 μM, β-catenin affecting cell proliferation and differentiation was activated, thereby increasing the expression of LEF-1 and cyclin D1 which are downstream factors of β-catenin.
[0112] Experimental Example 4: Promoting the expression of growth factors in human hair follicle dermal papilla cells
[0113] The effect of the peptide prepared in Preparation Example 1 above on the expression level of growth factors in human hair follicle dermal papilla cells (HHFDPC) was determined by RT-PCR.
[0114] HHFDPC was added at 4 × 10 5The density of cells / well was inoculated in 6-well cell culture plates and cultured for 24 hours under the conditions of mesenchymal stem cell complete medium. Then, the culture medium was replaced with serum-free mesenchymal stem cell culture medium and cultured for another 24 hours. The cultured cell cultures were treated with 500nM, 5μM, and 50μM of the peptides prepared in the above preparation example 1, respectively, minoxidil (MNX) was used as a positive control, and no substance was used as a negative control (con), and each was cultured for another 24 hours at 37°C. After washing each culture with PBS, RNA was isolated by treating the culture with 300μL of eaay blue (Intron, South Korea). Nano drop was used to quantify the isolated RNA, and cDNA synthesis was then performed using a cDNA synthesis kit (Enzynomics, South Korea). Then, PCR reaction was performed using a PCR premix (Enzynomics, South Korea) and the primers shown in Table 3 below. The PCR products were electrophoresed on 1.5% agarose gel, and the bands were detected using the Bio-Rad gel imaging system.
