Abstract
Description
[Technical Field]
[0001] The present invention relates to novel adiponectin-derived peptoid derivatives and uses thereof. [Background technology]
[0002] Skin aging is generally caused by both external and internal processes, such as increased wrinkling and sagging of the skin. External aging is commonly called "photoaging" because it is primarily caused by repeated exposure to ultraviolet rays (UV). While naturally aged skin is smooth, pale, and has fine lines, photoaged skin develops thick wrinkles, hyperpigmentation, and telangiectasia.
[0003] Subcutaneous fat plays an important role in maintaining energy homeostasis by secreting hormones and adipokines that regulate the metabolism of other tissues.Recently, it has been shown that ultraviolet radiation, an environmental factor that induces various diseases such as photoaging, inflammation, immunosuppression, and cancer, reduces the fat content of human subcutaneous adipose tissue, and adiponectin, a fat-derived product, decreases in aging skin, inducing an increase in MMP-1 and a decrease in collagen.
[0004]
[0005] The human body has approximately 1.3 million hairs, and the scalp has 100,000 to 150,000 hairs. Each hair grows, maintains, and falls out through three distinct cycles: anagen (the active growth phase), catagen (the apoptotic regression phase), and telogen (the resting phase). This cycle repeats over 3 to 6 years, resulting in an average of 50 to 100 hairs falling out each day. "Hair loss" generally refers to a condition in which there is less or no hair than normal due to some cause.
[0006] Currently, it is known that the causes of hair loss include internal factors such as the action of male hormones, and external factors such as mental stress in daily life and accumulation of lipid peroxides on the scalp, and that hair loss symptoms occur due to the complex interaction of these factors. Recently, the number of women suffering from hair loss has been increasing due to not only male pattern hair loss but also changes in dietary habits, increased stress caused by social environments, etc., and the number of people suffering from abnormal scalp and hair symptoms as described above is gradually increasing, and the age of those suffering is also getting younger.
[0007] Currently available hair growth drugs have the problems of lacking clear effects and side effects, needing to be taken continuously, and inducing side effects such as decreased sexual function, allergies, and depression.
[0008]
[0009] Metabolic disease is a syndrome in which risk factors such as obesity, diabetes, high blood pressure, arteriosclerosis, and nonalcoholic fatty liver disease (NAFLD) occur together due to excessive nutrient accumulation in the body and lack of exercise. Recently, it was officially named metabolic syndrome or insulin resistance syndrome through the Adult Treatment Program III established by the World Health Organization and the Heart, Lung, and Blood Institute of the National Institutes of Health. According to the ATP published by the US National Cholesterol Education Program (NCEP) in 2001, a patient is diagnosed with metabolic disease if they have three or more of the following five risk factors: abdominal obesity with a waist circumference of 40 inches (102 cm) or more for men and 35 inches (88 cm) for women; triglycerides of 150 mg / dL or more; HDL cholesterol of 40 mg / dL for men and 50 mg / dL or less for women; blood pressure of 130 / 85 mmHg or more; and fasting blood glucose of 110 mg / dL or more. For Asians, the waist circumference of 90 cm or more for men and 80 cm or more for women is slightly adjusted to be considered abdominal obesity. Recent research has shown that when these standards are applied, approximately 25% of the Korean population shows symptoms of metabolic syndrome.
[0010]
[0011] Adiponectin, a type of adipokine, a protein hormone secreted specifically by fat cells, is known to play an important role in regulating cardiovascular diseases such as hyperglycemia, hyperinsulinism, obesity, and arteriosclerosis by enhancing insulin function and suppressing insulin resistance, blocking inflammation and preventing fat accumulation in blood vessels. Adiponectin also inhibits cancer cell metastasis and inflammatory responses, and promotes not only keratinocyte proliferation but also the expression of filaggrin, hyaluronic acid, and extracellular matrix in the skin, thereby healing wounds, inhibiting fibrosis, improving skin wrinkles, and moisturizing the skin.
[0012] Adiponectin is composed of 244 amino acids and consists of a signal sequence, a collagen-like domain located at the N-terminus, and a C1q-like globular domain located at the C-terminus. The major oligomers are hexamers and 400 kDa high molecular weight complexes (HMW complexes), which are known to be more active than low molecular weight complexes (LMW complexes).
[0013] The development of peptides modified from adiponectin, which is known to have various physiological activities, has been a target for many researchers and pharmaceutical companies both in Japan and overseas, but the chances of ultimate success have been relatively low due to the difficulty of polymer formation in the body.
[0014] Recently, research has been conducted on peptoids, which are peptides with modified backbones that are more resistant to proteolysis. While these peptides have better pharmacokinetic properties than existing peptides, some have been reported to be cytotoxic.
[0015]
[0016] Under these circumstances, the present inventors developed short adiponectin-derived peptoids that have high physiological activity without cytotoxicity, and confirmed their effects of increasing adiponectin expression, promoting hair growth, and suppressing triglycerides, thereby completing the present invention.

[0080] R2 is at least one selected from the group consisting of a C1-C6 chain alkyl group, a C1-C6 ring alkyl group, a C2-C6 alkylcarboxyl group, and combinations thereof;
[0081] R 3、 R4 and R5 are the same or different and each independently represent a C7-C 12phenylalkyl group, pyridinylmethyl group, indolylmethyl group, benzodioxolomethyl group,
[0082] The phenylalkyl group is unsubstituted or is at least one selected from the group consisting of a hydroxy group, a trifluoromethyl group (CF), a halogen group, a cyano group, a nitro group, a C1-C6 chain alkyl group, a C1-C6 alkoxy group, and combinations thereof.
[0083]
[0084] In the present invention, the term "substitution" refers to a reaction in which an atom or an atomic group contained in a molecule of a compound is replaced with another atom or an atomic group.
[0085] In the present invention, the term "chain" refers to a molecule having a chain structure, which is a chemical structure in which carbon atoms are connected in a chain, and can be a straight chain or a branched structure.
[0086] In the present invention, the term "ring type" refers to a structure in which both ends of a chain formed by a skeleton of an organic compound are connected to form a ring.
[0087] In the present invention, the term "chain or ring-shaped alkyl group" means a monovalent linear, branched, or ring-shaped saturated hydrocarbon residue consisting solely of carbon and hydrogen atoms, having 1 to 12 carbon atoms. Examples of such alkyl groups include, but are not limited to, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, 2-butyl, 3-butyl, pentyl, n-hexyl, cyclobutyl, cyclopentyl, cyclohexyl, etc.

[0130] [Mode for Carrying Out the Invention] Embodiment 1. Production of peptoid derivatives of the present invention
[0131] The method for preparing the peptoid derivatives of the present invention is illustrated in Scheme 1 below. [Reaction Scheme 1]
[0132] [ka]
[0133] Peptoids can be easily synthesized using solid-phase synthesis. Using polymer beads bearing amine or hydroxyl groups as starting materials, peptoid residues can be easily introduced through a two-step reaction: bromoacetylation and amine substitution using a primary amine. Repeating this process allows efficient synthesis of peptoid oligomers. Peptoid derivatives according to one embodiment of the present invention were synthesized on resin beads by manual synthesis using a solid-phase submonomer protocol and by a microwave-assisted method.
[0134] Microwave synthesis was performed using a microwave oven (Whirlpool, 700W, 2450Hz). C-terminal amide peptoids were synthesized on resin beads using Fmoc-Rink amid MBHA resin (0.89 mmol / g, Novabiochem®, San Diego, CA, USA). All microwave-assisted reactions were performed at atmospheric pressure, and the initial reaction was performed at half-scale using resin beads (100 mg, 89 μmol). To remove the Fmoc protecting group from the resin, the Fmoc-Rink amid MBHA resin was reacted with 1 mL of 20% (v / v) piperidine in dimethylformamide (DMF) at room temperature for 10 minutes each, followed by washing the resin beads twice with dimethylformamide (DMF), methyl alcohol (MeOH), dichloromethane (DCM), and finally dimethylformamide (DMF). For bromoacetylation, bromoacetic acid (2M, 890 μL) dissolved in DMSO and N,N'-diisopropylcarbodiimide (2M, 890 μL) were added. The reaction solution was stirred and irradiated twice for 15 seconds using a microwave (700 W, 10% power) at room temperature. After the reaction, the resin beads were washed using dimethylformamide (DMF), methyl alcohol (MeOH), dichloromethane (DCM), and finally dimethylformamide (DMF), repeating the washing process twice each.
[0135] For the amine substitution reaction, the primary amine (2 M, 20 eq) was dissolved in dimethylformamide (DMF) and irradiated twice for 15 seconds using a microwave (700 W, 10% power) at room temperature. After the reaction, the resin beads were washed twice with dimethylformamide (DMF), methyl alcohol (MeOH), dichloromethane (DCM), and finally dimethylformamide (DMF). The second residue and polymer peptoid were synthesized by repeating the above process.
[0136] The peptoid residue, designated Ngly, was synthesized by peptide synthesis using 1-hydroxybenzotriazole (HOBt), N-[(dimethylamino)-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate N-oxide (HATU), N,N-diisopropylethylamine (DIEA), and Fmoc-Gly-OH in dimethylformamide (DMF) for 2 hours.
[0137]
[0138] On the other hand, when the N-terminus was protected with PEG or PAL, the synthesis was carried out as follows.
[0139] To synthesize peptoids protected with (PEG)3 (2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)acetic acid) or PAL (Palmitic acid), N-terminally unprotected peptoids synthesized by the peptoid synthesis method described above were reacted with 1-hydroxybenzotriazole (HOBt), N-[(dimethylamino)-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate N-oxide (HATU), N,N-diisopropylethylamine (DIEA), and PEG (2-(2-(2-(2-(2-aminoethoxy)ethoxy)ethoxy)acetic acid) or PAL (Palmitic acid) in dimethylformamide (DMF) for 2 hours with stirring. The reacted resin was washed twice with dimethylformamide (DMF), methyl alcohol (MeOH), dichloromethane (DCM), and finally dimethylformamide (DMF) to complete the washing process.
[0140]
[0141] The synthesized peptoid was separated from the resin by stirring in a separation solution (TFA:HO:TIPS = 95:2.5:2.5) at room temperature for 2 hours, and then the peptoid solution separated from the resin was distilled under reduced pressure to remove the solvent. The peptoid compound was purified using high-performance liquid chromatography (Prep-HPLC, Gilson) and purified using RP-HPLC and LC-MS to confirm and analyze its purity, yielding peptides with a purity of over 98% (Methods Enzymol. 267, 437-447 1996; Org Lett. 2002, 14;423:4057-9).
[0142]
[0143] The sequences and molecular weights of peptoid derivatives according to one embodiment of the present invention are shown in Table 2 below. [Table 2]
[0144] [Table 2]
[0145]
[0146] In Table 2, each monomer residue constituting the peptoid derivative of the present invention may have the following structure:
[0147] [ka]
[0148]
[0149] Test Example 1: Verification of in vitro AMPK phosphorylation activity
[0150] The effects of the peptoid derivatives of the present invention on adiponectin expression and receptor activity in mouse adipocytes, the main adiponectin-producing cells, were examined. The mouse adipocyte cell line 3T3-L1 was treated with each of the peptoid derivatives of the present invention at a concentration of 10 μM and cultured for 24 hours, after which the cells were harvested. Proteins were then extracted, and the effects on AMPK phosphorylation, which is responsible for the main downstream signaling of adiponectin, were examined by Western blot.
[0151] As a result, the peptoid derivatives of the present invention increased the AMPK phosphorylation activity related to the activation of adiponectin receptors in mouse adipocytes (Figures 1 to 8), and in particular, the peptoid derivatives represented by [Chemical Formula 1-3], [Chemical Formula 1-4], [Chemical Formula 1-9], and [Chemical Formula 1-16] were confirmed to have a significant effect of increasing AMPK phosphorylation activity compared to APN5, a conventionally known adiponectin-derived peptide (Table 3). [Table 3]
[0152] [Table 3]
[0153]
[0154] Test Example 2: Verification of loss of AMPK phosphorylation activity after in vitro adiponectin receptor 1 knockdown
[0155] To verify whether the peptoid derivatives of the present invention bind to adiponectin receptor 1, a mouse adipocyte cell line, 3T3-L1, was knocked down by treating it with siRNA for adiponectin receptor 1, and then treated with each of the peptoid derivatives of the present invention at a concentration of 10 μM. After culturing for 24 hours, the cells were harvested. Proteins were then extracted, and Western blotting was performed to determine whether the increased AMPK phosphorylation activity caused by the peptoid derivatives had disappeared.
[0156] As a result, it was confirmed that the peptoid derivatives of the present invention, including [Chemical Formula 1-3], [Chemical Formula 1-4] to [Chemical Formula 1-9], and [Chemical Formula 1-16], reduce AMPK phosphorylation activity after knockdown of adiponectin receptor 1 (Figure 9).
[0157] Adiponectin acts by binding to adiponectin receptors, and activation of the adiponectin receptors is known to increase the phosphorylation of AMPK and the activity of PPARα / PPARγ, which are downstream signaling pathways (Crystal structures of the human adiponectin receptors. Nature. 2015 Apr16;5207547:312-6. doi:10.1038 / nature14301). Furthermore, the expression of adiponectin and its receptors is reduced in photoaged skin and skin exposed to UV rays. This reduced expression of adiponectin can worsen photoaging by regulating the expression of MMP-1 and procollagen, which are regulators of skin aging, and altering the extracellular matrix (UV-induced inhibition of adipokine production in subcutaneous fat aggravates dermal matrix degradation in human skin. 2016. Scientific Reports. 10;6:25616. doi:10.1038 / srep25616).
[0158] Therefore, it is suggested that the peptoid derivatives of the present invention increase the activity of AMPK phosphorylation related to the activity of adiponectin receptors, thereby increasing the expression of adiponectin in the body and playing a major role in preventing skin aging.
[0159]
[0160] Test Example 3: Verification of in vitro cytotoxicity
[0161] Four types of cell lines (3T3-L1 adipocytes, RD muscle cells, keratinocytes, and fibroblasts) were used, and each cell was grown in a 24-well plate at 5 × 10 cells per well. 4The cells were then aliquoted and cultured for 24 hours under the appropriate cell culture conditions. The medium was discarded, washed with PBS, and replaced with fresh medium without 10% FBS. The cells were treated with the peptoid derivatives of the present invention at various concentrations (0, 0.1, 1, 10, 100, and 500 μM) and cultured for 24 hours. The medium was again carefully removed and washed with PBS. MTT reagent was added according to the manufacturer's instructions, and the cells were incubated at room temperature for 30 minutes, after which the absorbance was measured at 450 nm.
[0162] As a result, it was confirmed that the peptoid derivatives of the present invention, including [Chemical Formula 1-4] and [Chemical Formula 1-9], were non-toxic in multiple cell lines (FIGS. 10 and 11).
[0163]
[0164] Test Example 4: Verification of concentration dependency of in vitro AMPK phosphorylation activity
[0165] The mouse adipocyte cell line 3T3-L1 was treated with a series of peptoid derivatives of the present invention at various concentrations (0, 0.01, 0.1, 1, 10, and 100 μM) and cultured for 24 hours. After cell collection, proteins were extracted and the concentration-dependent effect of the peptoid derivatives on AMPK phosphorylation was examined by Western blotting.
[0166] As a result, it was confirmed that the peptoid derivatives of the present invention, including [Chemical Formula 1-4] and [Chemical Formula 1-9], increase the AMPK phosphorylation activity in a concentration-dependent manner (FIG. 12).
[0167]
[0168] Test Example 5. Solubility test
[0169] PRISMA HT solution was diluted with distilled water at a ratio of 1:40 and adjusted to pH 7.4 to be used as a test buffer. In addition, reference substances (Diclofenac stock 50 mM, Phenazopyridine stock 25 mM) used for accuracy in general solubility tests and the peptoid derivative of the present invention (50 mM) as a test substance were prepared in DMSO and used as test standard solutions.
[0170] 10 mL of the prepared test substance was diluted with 190 μL of isopropyl alcohol. A blank sample was prepared by mixing 75 mL of test solution with 70 mL of isopropyl alcohol, and 5 mL of the test substance diluted in isopropyl alcohol was added to the blank sample. After mixing the diluted sample, the absorbance was measured and used as the initial test value. For the solubility test, 1 mL of test solution was mixed with 10 mL of DMSO test standard solution and incubated at room temperature for 24 hours. The sample was then used to remove precipitates using a filter plate. 75 mL of isopropyl alcohol was added to 74 mL of the filtered sample, and the absorbance was measured and used as the sample value.
[0171] The solubility values of the test substances were determined by measuring the absorbance of each sample using a microplate reader and then analyzing it using MSOL Explorer (Solubility Explorer program). The average and standard deviation of three replicate test values (n = 3) were calculated using an Excel program.
[0172] As a result, the peptoid derivatives of the present invention exhibited excellent solubility in DMSO (Table 4).
[0173] [Table 4]
[0174]
[0175] Test Example 6. Plasma stability test
[0176] The peptoid derivatives of the present invention were added to two types of plasma (human and rat) at a concentration of 1 μM, placed in separate tubes, and incubated at 37°C for various time periods (0, 30, 60, 120, and 240 minutes). After each incubation period, the plasma tubes were removed, an acetonitrile solution containing an internal standard (chlorpropamide) was added, vortexed for 5 minutes, and centrifuged (14,000 rpm, 4°C) for 5 minutes. The supernatant was then injected into an LC-MS / MS system to analyze the drug at each time point, thereby assessing the plasma stability of the peptoid derivatives. Procaine and enalapril were used as reference substances to ensure accuracy in general plasma stability tests.
[0177] The amount of drug remaining in each tube after the reaction was analyzed by LC-MS / MS using a Shimadzu Nexera XR system and a TSQ vantage (Thermo). The HPLC column used was a Luna C18 column (2.0 x 50 mm, 3 μm particle size; Phenomenex, US), and the mobile phase was 0.1% formic acid in distilled water (A) and 0.1% formic acid in acetonitrile (B). Data analysis was performed using Xcalibur (version 1.6.1). The plasma stability of each peptoid derivative was shown as the percentage remaining at each time point relative to the unincubated sample.
[0178] As a result, it was confirmed that the peptoid derivatives of the present invention have excellent plasma stability, and in particular, their plasma stability is significantly improved compared to APN5, a conventionally known adiponectin-derived peptide (Table 5).
[0179] [Table 5]
[0180]
[0181] Test Example 7. Metabolic stability test
[0182] Three types of liver microsomes (human, rat, mouse, 0.5 mg / ml) were added to 0.1 M phosphate buffer (pH 7.4) and the peptoid derivative of the present invention at a concentration of 1 μM. The mixture was then pre-incubated at 37°C for 5 minutes, followed by the addition of an NADPH regeneration system solution and incubation at 37°C for 30 minutes. To terminate the reaction, an acetonitrile solution containing an internal standard (chlorpropamide) was added, followed by centrifugation (14,000 rpm, 4°C) for 5 minutes. The supernatant was then injected into an LC-MS / MS system to analyze the substrate drug and evaluate metabolic stability. Verapamil was used as a reference substance to ensure accuracy in general plasma stability tests.
[0183] The amount of substrate remaining after the reaction was analyzed by LC-MS / MS using an Agilent 1290 infinity series pump system (Agilent, USA) and a Triple Quad 5500 LC-MS / MS system (Applied Biosystems, USA). The HPLC column used was a Kinetex C18 column (2.1 × 100 mm, 1.7 μm particle size; Phenomenex, USA). The mobile phase was 0.1% formic acid in distilled water (A) and 0.1% formic acid in acetonitrile (B). The MS / MS ion source was TurboSpray ionization, and the mass analyzer was a Triple quadruple type. The metabolites produced were quantified using multiple reaction monitoring (MRM) quantification mode, and data analysis was performed using Analyst software (version 1.6.1).
[0184] As a result, it was confirmed that the peptoid derivatives of the present invention have excellent metabolic stability, and in particular, their metabolic stability is significantly improved compared to APN5, a conventionally known adiponectin-derived peptide (Table 6).
[0185] [Table 6]
[0186] Test Example 8. CYP Inhibition Analysis
[0187] Human liver microsomes (0.25 mg / ml) were mixed with 0.1 M phosphate buffer (pH 7.4), a cocktail of five drug-metabolizing enzyme substrates (phenacetin 50 μM, S-mephenytoin 100 μM, dextromethorphan 5 μM, midazolam 2.5 μM, diclofenac 10 μM), and the peptoid derivatives of the present invention at 0 and 10 μM concentrations, and then incubated at 37°C for 5 minutes. An NADPH regeneration system solution was then added and incubated at 37°C for 15 minutes. To terminate the reaction, an acetonitrile solution containing an internal standard (chlorpropamide) was added, followed by centrifugation for 5 minutes (14,000 rpm, 4°C). The supernatant was then injected into an LC-MS / MS system to simultaneously analyze the metabolites of the drug substrates, thereby assessing the inhibitory activity of the peptoid derivatives against drug-metabolizing enzymes. Ketoconazole was used as a reference substance to ensure accuracy when assessing the inhibitory activity of common drug-metabolizing enzymes.
[0188] The metabolites of each CYP isoenzyme-indicating drug produced through the reaction were analyzed by LC-MS / MS using a Shimadzu Nexera XR system and a TSQ vantage (Thermo). The HPLC column used was a Kinetex C18 column (2.1 × 100 mm, 2.6 μm particle size; Phenomenex, USA), and the mobile phase was 0.1% formic acid in distilled water (A) and 0.1% formic acid in acetonitrile (B). The MS / MS ion source was TurboSpray ionization, and the mass analyzer was a Triple Quadrupole type. The metabolites produced were quantified using multiple reaction monitoring (MRM) quantification mode, and data analysis was performed using Xcalibur (version 1.6.1).
[0189] As a result, the peptoid derivatives of the present invention inhibit CYP enzymes including CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 (Table 7), suggesting that they do not cause fatal abnormal reactions due to drug interactions.

[0191]
[0192] Test Example 9: Evaluation of the efficacy of hair growth and skin aging improvement after application to mice
[0193] After shaving the backs of 7-week-old C57BL / 6 mice, the peptoid derivative formulations of the present invention were dissolved in a vehicle (EtOH:polyethylene glycol=30:70, v / v) at a concentration of 0.15 mM and applied to the backs. 200 μl of the solution per mouse was applied evenly over the entire back every day for 35 days.
[0194] In addition, after the final application, skin tissue was removed and mRNA was extracted, and the effect on the expression of procollagen, a factor in skin aging, was verified using real-time PCR.
[0195] As a result, the ratio of hair growth sites among the first hair removal sites was significantly increased in the group treated with the peptoid derivative of the present invention. In particular, it was confirmed that hair follicle formation was promoted, similar to the group treated with minoxidil, which was used as a positive control (Figure 13).
[0196] Furthermore, it was confirmed that procollagen, a factor in skin aging, was expressed in a manner similar to or even greater than APN5, a conventionally known adiponectin-derived peptide, in the group treated with the peptoid derivative of the present invention (Figure 14).
[0197]
[0198] Test Example 10. Verification of the effect of suppressing neutral fat in adipocytes
[0199] The mouse adipocyte cell line 3T3-L1 was differentiated into adipocytes by treatment with a differentiation-inducing agent, and the cells were filled with triglycerides. After treatment with a series of concentrations (10, 30 μM) of the peptoid derivatives of the present invention and culturing for 24 hours, the cells were harvested and the triglyceride content was measured. As a result, it was confirmed that treatment with the peptoid derivatives of the present invention reduced the triglyceride content in a concentration-dependent manner (FIG. 15A).
[0200] On the other hand, mouse adipocyte cell line 3T3-L1 was differentiated into adipocytes by treating with 10 μM of the peptoid derivative of the present invention together with a differentiation-inducing reagent prior to differentiation induction, and the cells were then isolated and the triglyceride content was measured. As a result, it was confirmed that treatment with the peptoid derivative of the present invention inhibited the accumulation of triglycerides (FIG. 15B).
[0201]
[0202] Test Example 11: Verification of the effectiveness of muscle cells in improving sensitive skin
[0203] After culturing the RD cell line, a human muscle cell line, the medium was changed to serum-free medium when the cells reached 90% fullness, and the medium was treated with 50 mM lactic acid (LA), a sensitive skin inducer, and 10 μM of the peptoid derivative of the present invention. After 4 hours, the cells were harvested and mRNA was extracted to observe the effect on the expression of CGRP, a neurotransmitter that mediates pain.
[0204] As a result, it was confirmed that the expression of pain mediators was significantly reduced when treated with the peptoid derivatives of the present invention compared to when treated with lactic acid, and that the levels were similar to or lower than when not treated with either compound (Figure 16).In other words, it was found that the peptoid derivatives of the present invention significantly suppressed the expression of genes related to skin sensitivity induced by lactic acid.
