Description

Pharmaceutical composition for the prevention or treatment of skin diseases

[0001] The present disclosure relates to a pharmaceutical composition for preventing or treating skin diseases.

[0002] Generally, skin diseases can be classified into systemic skin diseases, local skin diseases, skin infections, and minor skin damage. Systemic skin diseases include psoriasis, eczema, atopic dermatitis, contact dermatitis, seborrheic dermatitis, bullous diseases, lichen planus, erythema multiforme, photosensitivity, drug-induced rashes, pruritus, and purpura. Local skin diseases include acne, rosacea, heat rash, hyperhidrosis, vitiligo, freckles, moles, skin cancer, basal cell carcinoma, squamous cell carcinoma, malignant melanoma, Kaposi's sarcoma, actinic keratosis, discoid lupus erythematosus, skin tags, seborrheic keratosis, sebaceous cysts, calluses and corns, keloids, stretch marks, chilblains, leg ulcers, and bedsores.

[0003] Additionally, skin infections include furuncles, impetigo, folliculitis, cellulitis, ringworm, athlete's foot, tinea versicolor, herpes simplex, warts, and scabies, while minor skin injuries include cuts, scrapes, needlestick injuries, sunburn, blisters, and bruises.

[0004] Among skin diseases, psoriasis and atopic dermatitis, which are systemic skin diseases with a significant increase in patient numbers due to industrial development and climate change, are among them. Psoriasis is a non-contagious, chronic autoimmune skin disease characterized by erythema and thickening of the skin due to excessive keratin production on the skin's surface. In other words, psoriasis is a chronic autoimmune disease that occurs when the immune system, which should be attacking external microorganisms or irritants, instead attacks the skin itself.

[0005] Clinically, five different forms of psoriasis have been reported: plaque psoriasis, pustular psoriasis, guttate psoriasis, intertrigo psoriasis, and erythrodermic psoriasis. Treatment may vary depending on the type.

[0006] Numerous studies have shown that the pathological factors of psoriasis are linked to immune system abnormalities. Currently, molecular biological mediators that induce an excessive immune response include inflammatory cytokines, such as Tumor Necrosis Factor-alpha (TNF-α), Interleukin-17A (IL-17A), Interleukin-23 (IL-23), and Interleukin-33 (IL-33). Of these, IL-17A and IL-23 have the greatest impact.

[0007] Topical treatments for psoriasis (e.g., topical treatments) include vitamin D derivatives, steroids, and combinations of vitamin D derivatives and steroids. These drugs mainly promote differentiation of normal cells, inhibit proliferation of keratinocytes, and have anti-inflammatory or itching effects.

[0008] Meanwhile, atopic dermatitis is a chronic, intractable inflammatory skin disease characterized by itching, redness, lichenification, and skin infections. In skin affected by atopic dermatitis, various T cell subtypes, including Th2 (T helper 2), Th22, and Th17 cells, increase, resulting in damage to the skin barrier.

[0009] When the epidermal defense is damaged by pathological factors such as allergens, irritants, and microorganisms, a local inflammatory response is triggered, which induces a chain reaction of immune responses. In the body, Thymic Stromal Lymphopoietin (TSLP) is secreted, which activates Th2 cells and releases interleukin-4 (IL-4), interleukin-5 (IL-5), interleukin-13 (IL-13), and interleukin-31 (IL-31). Among these, interleukin-4 and interleukin-13 have the greatest effect.

[0010] Topical medications for atopic dermatitis include calcineurin inhibitors (e.g., tacrolimus, pimecrolimus, etc.), steroids (e.g., betamethasone, desonide, etc.), antihistamines (e.g., hydroxyzine, diphenhydramine, etc.), and antibiotics (e.g., azithromycin, mupirocin, etc.).

[0011] Additionally, fungi that cause inflammatory skin diseases include Staphylococcus aureus, Candida albicans, and Malassezia sympodialis.

[0012] However, a number of adverse effects (e.g., skin atrophy, growth retardation, malignant tumors, lymphopenia, vomiting, abdominal pain, nephrotoxicity, osteoporosis, avascular necrosis, hypertension, headache, bacterial and viral infections, etc.) that appear in drugs and therapies for the treatment of psoriasis and atopic dermatitis are widely reported as side effects.

[0013] Therefore, there is an urgent need for a treatment for psoriasis and atopic dermatitis that suppresses itching, prevents infection by various pathogens, effectively restores damaged skin barriers, and has no side effects.

[0014] The present inventors have made diligent efforts to develop a pharmaceutical composition that, compared to existing single-component preparations that bind to the aryl hydrocarbon receptor (AhR) and regulate the activity of the aryl hydrocarbon receptor, more effectively kills bacteria in inflamed areas of psoriasis and atopic dermatitis, improves the stability of pharmaceutical preparations used for psoriasis and atopic dermatitis, and further enhances the inhibitory effect on inflammatory cytokines that cause psoriasis and atopic dermatitis, and as a result, have completed the present invention.

[0075] [Chemical Formula 2]

[0076]

[0077] In one embodiment, the octenidine salt is a pharmaceutically acceptable salt of octenidine, which may include at least one selected from an inorganic ionic salt, an inorganic acid salt, an organic acid salt, a sulfonate salt, an amino acid salt, and an amine salt of octenidine.

[0078] For example, pharmaceutically acceptable salts of octenidine include inorganic ionic salts prepared with calcium, potassium, sodium or magnesium, etc.; inorganic salts prepared with hydrochloric acid, nitric acid, phosphoric acid, hydrobromic acid, iodic acid, perchloric acid or sulfuric acid, etc.; organic salts prepared with acetic acid, trifluoroacetic acid, citric acid, maleic acid, succinic acid, oxalic acid, benzoic acid, tartaric acid, fumaric acid, mandelic acid, propionic acid, lactic acid, glycolic acid, gluconic acid, galacturonic acid, glutamic acid, glutaric acid, glucuronic acid, aspartic acid, ascorbic acid, carbonic acid or vanillic acid, etc.; sulfonic salts prepared with methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, salicylic acid, p-toluenesulfonic acid or naphthalenesulfonic acid, etc.; amino acid salts prepared with glycine, arginine or lysine, etc.; Or amine salts prepared with trimethylamine, triethylamine, ammonia, pyridine or picoline; etc.; but the types of octenidine salts are not limited by these listed salts.

[0079] As a specific example, a pharmaceutically acceptable salt of octenidine may be octenidine dihydrochloride. Octenidine dihydrochloride (CAS registration number: 70775-75-6) is a white or light yellow powder and is a pyridine compound.

[0082]

[0083] In one specific example, octenidine dihydrochloride exhibits excellent bactericidal effects by strongly adsorbing to the cell surface of anionic bacteria, binding to phospholipids and anionic polysaccharides in the cell membrane, and impairing cell function, causing plasma membrane leakage and inhibiting mitochondrial function. Furthermore, octenidine dihydrochloride exhibits excellent anti-inflammatory properties by inhibiting Langerhans gland cell activation and suppressing the secretion of inflammatory cytokines.

[0084] Psoriasis is an inflammatory skin disease caused by the expression of inflammatory cytokines (e.g., TNF-α, IL-17A, IL-23, IL-33, etc.), which are molecular biological mediators that induce an excessive immune response. Of these, IL-17A and IL-23 have the greatest impact. The main pathogens causing infections in psoriasis include Staphylococcus aureus and Candida albicans.

[0085] Atopic dermatitis is an inflammatory skin disease caused by the secretion of lymphopoietin from the thymic stroma, which activates Th2 cells to release IL-4, IL-5, IL-13, and IL-31. Among these, IL-4 and IL-13 have the greatest effect. The main pathogens causing infections caused by atopic dermatitis include Staphylococcus aureus and Malassezia sympodialis.

[0086] A pharmaceutical composition for preventing or treating psoriasis and atopic dermatitis according to one embodiment can strongly kill bacteria and fungi through a complex antibacterial action, and thus its effect shows a much better antibiotic effect than a single preparation containing only an aryl hydrocarbon receptor modulator component, and can significantly improve the effect of preventing and treating inflammatory skin diseases.

The antimicrobial activity evaluation was performed by calculating the minimum growth inhibitory concentration (MIC) for each microorganism. 90: The results of comparing Control Examples 1 to 3 and Manufacturing Examples 1 to 12 as Minimum Inhibitory Concentration (MIC) are as shown in Tables 4, 5, and 6 below. The minimum growth inhibitory concentration test was conducted according to the CLSI (Clinical and Laboratory Standards Institute) standards. For the Gram-positive bacteria Staphylococcus aureus, the test was conducted using the CLSI M07-A10:2015 test method, and for the yeasts Candida albicans and Malassezia sympodialis, the test was conducted using the CLSI M27-A3:2008 test method.

[0135] 1) Pre-culture of test bacteria

[0136] ① Staphylococcus aureus: Inoculated onto Tryptic Soy Agar (TSA) medium and cultured at 35±2℃ for 16 to 24 hours.

[0137] ②Candida albicans, Malassezia sympodialis: Inoculated onto Sabouraud Dextrose Agar (SDA) medium and cultured at 35±2℃ for 20 to 24 hours.

[0138] 2) Preparation of test bacterial solution and spore suspension

[0139] ① Staphylococcus aureus: 1×10 6 The solution was diluted in Cation-Adjusted Muller-Hinton Broth (CAMHB) medium to CFU / ml and used as a test bacterial solution.

[0140] ②Candida albicans, Malassezia sympodialis: After buffering 0.165 mol / L of 3-N-morpholinopropane sulfonic acid (MOPS: 3-N-morpholinopropane sulfonic acid) in RPMI 1640 medium (RPMI1640, Gibco), a spore suspension of 5.0×10²~2.5×10³ CFU / ml was prepared and used as a test bacterial solution.

[0141] 3) Inoculation of test bacteria solution

[0142] ① Staphylococcus aureus: 1 ml of the test bacteria solution was inoculated into each tube containing the test solution at each concentration. A tube containing 2 ml of the solution (Control Examples 1-3, Preparation Examples 1-12) on CAMHB medium was used as a negative control group, and a tube containing 1 ml of the solution (Control Examples 1-3, Preparation Examples 1-12) and 1 ml of the test bacteria solution on CAMHB medium was used as a positive control group. The tubes that had been treated with the test bacteria solution were cultured at 35±2℃ for 16-24 hours.

[0143] ②Candida albicans, Malassezia sympodialis: 0.9 ml of the test bacteria solution was inoculated into each well containing the test solution at each concentration. A well containing 1.0 ml of the solution (Control Examples 1 to 3, Preparation Examples 1 to 12) in RPM 1640 medium buffered with MOPS 0.165 mol / L was used as a negative control group, and a well containing 0.1 ml of the solution (Control Examples 1 to 3, Preparation Examples 1 to 12) and 0.9 ml of the test bacteria solution in RPM 1640 medium buffered with MOPS 0.165 mol / L was used as a positive control group. The tubes that had been treated with the test bacteria solution were cultured at 35±2℃ for 24 to 48 hours.

[0144] 4) Judging the results

[0145] After incubation, the minimum concentration at which no bacterial growth occurred was considered the minimum growth inhibitory concentration. After incubation, no bacterial growth should be observed in the negative control group, and bacterial growth should be observed in the positive control group. The results obtained using the above antibacterial activity test method are presented in Tables 4, 5, and 6.

[0149] As can be seen from the results in Tables 4, 5 and 6 above, the compositions according to Manufacturing Examples 1 to 12 showed significantly increased antibacterial activity against Staphylococcus aureus, Candida albicans and Malassezia sympodialis compared to the control examples 1 to 3 that did not contain octenidine dihydrochloride. The antibacterial activity of Manufacturing Examples 1 to 4 increased by 2.7 to 9.2 times compared to the antibacterial activity against Staphylococcus aureus of Control Example 1, by 2.8 to 9 times compared to the antibacterial activity against Candida albicans, and by 2.5 to 8.7 times compared to the antibacterial activity against Malassezia symphodialis. The antibacterial activity of Manufacturing Examples 5 to 8 increased by 2.5 to 8.6 times compared to the antibacterial activity against Staphylococcus aureus of Control Example 2, by 2.6 to 8.4 times compared to the antibacterial activity against Candida albicans, and by 2.4 to 8.1 times compared to the antibacterial activity against Malassezia symphodialis.

[0150] The antibacterial activity of Preparation Examples 9 to 12 was 2.3 to 8.4 times higher than that of Control Example 3 against Staphylococcus aureus, 2.2 to 7.3 times higher than that of Control Example 3 against Candida albicans, and 2.3 to 8 times higher than that of Malassezia sympodialis. Therefore, the pharmaceutical compositions according to Preparation Examples 1 to 12 showed good susceptibility test results against the causative agents of psoriasis and atopic dermatitis, and thus can be expected to show excellent clinical treatment results.

[0151] Test Example 2. Storage Stability Evaluation

[0152] Each sample from Control Examples 1 to 3 and Manufacturing Examples 1 to 12 was taken in an amount of 10 ml and placed in a 20 ml vial, sealed hermetically, and stored at 45°C for 4 weeks. The UV-visible absorption spectra of the samples at the beginning and after 4 weeks at 45°C were measured. That is, the absorbance was measured at 500 nm using a spectrophotometer (Mega-800, Scinco, Korea), and the results are shown in Table 7 below.

[0154] As described in Table 7, the solutions of Preparation Examples 1 to 12 showed improved stability compared to Control Examples 1 to 3 that did not contain octenidine dihydrochloride. In the 500 nm absorbance measured after 4 weeks, Control Example 1 showed an absorbance increase of about 6%, whereas Preparation Examples 1 to 4 showed an increase of about 1 to 2%, Control Example 2 showed an absorbance increase of about 6%, whereas Preparation Examples 5 to 8 showed an increase of about 1 to 2%, and Control Example 3 showed an absorbance increase of about 7%, whereas Preparation Examples 9 to 12 showed an increase of about 1 to 2%. Therefore, it can be seen that the compositions of Preparation Examples 1 to 12 showed superior stability compared to Control Examples 1 to 3 even after 4 weeks at 45°C.

[0155] Test Example 3. Evaluation of the ability to suppress inflammatory cytokines

[0156] The ability to suppress inflammatory cytokines was evaluated for Control Examples 1 to 3 and Manufacturing Examples 1 to 12 using the method described below.

[0157] (1) Ability to suppress cytotoxicity and inflammatory cytokines in keratinocytes

[0158] Keratinocytes (HaCaT) were purchased from the Korean Cell Line Bank (Seoul, Korea). Keratinocytes were cultured in DMEM (Dulbecco's Modified Eagle Medium; Gibco BRL., USA) containing 10% heat-inactivated fetal bovine serum (HIFBS; Gibco BRL., USA) and 1% penicillin / streptomycin (penicillin 100 IU / ml, streptomycin 100 μg / ml; Thermo Fisher Scientific) at 37°C in an incubator with 5% CO₂ for 24 h.

[0159] ① Cytotoxicity assessment (MTT Assay)

[0160] 1×10 cultured keratinocytes 6100 μl was dispensed into a 96-well plate at cells / ml and cultured for 24 hours at 37°C and 5% CO₂ conditions. The medium was removed, and 100 μl of DMEM medium and 100 μl of sample (control examples 1-3, preparation examples 1-12) were added to each well and cultured for 24 hours. After 24 hours, 100 μl of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) solution (0.5 mg / ml, Sigma Aldrich, St. Louis, MO, USA) was added to each well and cultured for 4 more hours to reduce MTT, and the supernatant was removed. Afterwards, 100 μl of dimethyl sulfoxide (DMSO) was dispensed into each well and mixed for 1 hour, and then the absorbance was measured at 540 nm using an ELISA microplate reader (Enzyme-Linked Immunosorbent Assay microplate reader; Bio-Rad model 680, Bio-Rad Laboratories INC., Tokyo, Japan). The cell viability was calculated as the percentage of the absorbance of the sample-added group compared to the absorbance of the sample-free group, and the results are shown in Table 8.

[0161] * Cell viability (%) = (absorbance of sample added group / absorbance of sample-free group) × 100

[0162] ② Ability to suppress inflammatory cytokines

[0163] Keratinocytes were seeded at 5 × 10 per well in a 96-well plate. 5The cells were seeded and cultured for 24 hours, and the supernatant was washed with phosphate-buffered saline (PBS). To induce an immune response in keratinocytes, 10 ng / ml of TNF-α (Tumor Necrosis Factor-α) and 10 ng / ml of IFN-γ (Interferon-γ) were added to DMEM medium without HIFBS, and Control Examples 1 to 3 and Preparation Examples 1 to 12 were each treated at 100 μg / ml, and cultured for 24 hours. Then, the concentrations of IL-17A and IL-23 in the supernatant of keratinocytes were measured using an ELISA kit (MAX DELUXE; BioLegend, USA).

[0164] Briefly, ELISA plates were coated with 100 μl of diluted (1x) capture antibody and incubated at 4°C for 24 h, washed four times with washing buffer (0.05 v / v% Tween-20 mixed in PBS), and then 200 μl of blocking buffer (3 w / v% bovine serum albumin mixed in Tris-buffered saline, pH 7.6) was added, incubated with shaking at room temperature for 1 h, and then washed four times with washing buffer. IL-17A and IL-23 standards were diluted to a concentration range of 0 to 1,000 pg / ml, and 100 μl each was added to the wells of the ELISA plate along with the samples. The plates were incubated with shaking at room temperature for 2 hours and washed four times. 100 μl of the detection antibody was added, incubated with shaking at room temperature for 1 hour, and washed four times. 100 μl of the Avidin-Horseradish peroxidase (1:1,000) reagent was then added, incubated with shaking at room temperature for 30 minutes, and washed five times. Finally, 100 μl of TMB (3,3',5,5'-Tetramethyl benzidine) substrate solution was added, and the mixture was incubated in the dark for 30 minutes. After adding 100 μl of stop solution (2 N H2SO4), the absorbance was measured at 450 nm within 15 minutes using a microplate reader (Bio TeK Instruments, Inc. Vermont, USA), and the inhibitory concentration of each cytokine was listed in Table 8.

[0166] As can be seen from the results in Table 8, the compositions of Preparation Examples 1 to 12 showed significantly increased inhibitory effects on IL-17A and IL-23 compared to Control Examples 1 to 3 that did not contain octenidine dihydrochloride. The inhibitory effects of Preparation Examples 1 to 4 were 2.8 to 5.3 times higher for IL-17A and 2.8 to 5.5 times higher for IL-23 than Control Example 1. The inhibitory effects of Preparation Examples 5 to 8 were 2.7 to 5.7 times higher for IL-17A and 2.6 to 5.1 times higher for IL-23 than Control Example 2. The inhibitory effects of Preparation Examples 9 to 12 were 2.3 to 5.9 times higher for IL-17A and 2.5 to 5.3 times higher for IL-23 than Control Example 3. Therefore, the pharmaceutical compositions of Manufacturing Examples 1 to 12 exhibit good inhibitory effects on the major cytokines (IL-17A, IL-23) that cause psoriasis, and thus, it can be predicted that they will show excellent clinical treatment results.

[0167] (2) Ability to suppress cytotoxicity and inflammatory cytokines in mast cells

[0168] Mast cells (HMC-1: Human Mast Cell-1) were purchased from the Korea Cell Line Bank (Seoul, Korea). Mast cells were cultured in IMDM (Iscove's Modified Dulbecco's Medium, Gibco BRL, USA) containing 10% heat-inactivated fetal bovine serum (HIFBS; Gibco BRL, USA) and 1% penicillin / streptomycin (penicillin 100 IU / ml, streptomycin 100 μg / ml; Thermo Fisher Scientific) at 37°C in a 5% CO2 incubator for 24 h.

The medium was removed, and 100 μl of DMEM medium and 100 μl of sample (control examples 1-3, preparation examples 1-12) were added to each well and cultured for 24 hours. After 24 hours, 100 μl of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) solution (0.5 mg / ml, Sigma Aldrich, St. Louis, MO, USA) was added to each well and cultured for 4 more hours to reduce MTT, and the supernatant was removed. Afterwards, 100 μl of DMSO was dispensed into each well, mixed for 1 hour, and the absorbance was measured at 540 nm using an ELISA microplate reader (Bio-Rad model 680, Bio-Rad Laboratories INC., Tokyo, Japan). Cell viability was calculated as the percentage of the absorbance of the sample-added group compared to the absorbance of the sample-free group, and the results are shown in Table 9.

[0171] * Cell viability (%) = (absorbance of sample added group / absorbance of sample-free group) × 100

[0172] ② Ability to suppress inflammatory cytokines

[0173] Mast cells were seeded at 5×10 per well in a 96-well plate. 5 After seeding with a cell line and culturing for 24 hours, 20 nM of PMA (Phorbol 12-myristate 13 acetate) and 1 μM of calcium ionophore (Calcium ionophore A23187) were added to each well, and simultaneously, Control Examples 1 to 3 and Manufacturing Examples 1 to 12 were treated at a concentration of 100 μg / ml each, and then cultured in an incubator at 37°C and 5% CO2 for 8 hours. After the culture was completed, the culture solution was centrifuged (2,000 rpm, 5 minutes) and the supernatant was collected. To confirm the concentration of each cytokine (IL-4, IL-13) contained in the supernatant using an ELISA kit (LEGEND MAX; BioLegend, USA), the absorbance was measured at 450 nm using an ELISA microplate reader (Bio-Rad model 680, Bio-Rad Laboratories INC., Tokyo, Japan), and the inhibitory concentration of each cytokine is shown in Table 9.

[0175] As can be seen from the results in Table 9, the compositions of Preparation Examples 1 to 12 showed significantly increased inhibitory effects on IL-4 and IL-13 compared to Control Examples 1 to 3 that did not contain octenidine dihydrochloride. The inhibitory effects of Preparation Examples 1 to 4 were 2.8 to 5.2 times higher for IL-4 and 2.6 to 5.4 times higher for IL-13 than Control Example 1. The inhibitory effects of Preparation Examples 5 to 8 were 2.4 to 5.6 times higher for IL-4 and 2.5 to 5.1 times higher for IL-13 than Control Example 2. The inhibitory effects of Preparation Examples 9 to 12 were 2.4 to 5.4 times higher for IL-4 and 2.5 to 5.6 times higher for IL-13 than Control Example 3. Therefore, since the pharmaceutical compositions of Manufacturing Examples 1 to 12 exhibit good inhibitory effects on the major cytokines (IL-4, IL-13) that cause atopic dermatitis, it can be predicted that they will also show excellent therapeutic results clinically. Fig. 1 is a graph showing the results of an inhibitory effect experiment on IL-17A and IL-23 according to Control Example 1 and Manufacturing Example 1. Referring to Fig. 1, it can be seen that the composition according to Manufacturing Example 1 has a superior inhibitory effect on IL-17A and IL-23 compared to Control Example 1. Fig. 2 is a graph showing the results of an inhibitory effect experiment on IL-4 and IL-13 according to Control Example 1 and Manufacturing Example 1. Referring to Fig. 2, it can be seen that the composition according to Manufacturing Example 1 has a superior inhibitory effect on IL-4 and IL-13 compared to Control Example 1.

[0176] Test Example 4. Evaluation of the ability to suppress crystal precipitation during low-temperature storage

[0177] In order to evaluate the ability to inhibit crystal precipitation during low-temperature storage, solutions containing tapinarope and octenidine dihydrochloride were prepared according to the ingredients and compositions in Tables 10, 11, and 12 as follows. Ethanol and dimethyl sulfoxide were added to three preparation containers at room temperature (25°C), and tapinarope was added to each preparation container to dissolve, and then octenidine dihydrochloride, polyethylene glycol 400, diisopropyl adipate, isopentyl diol, hexylene glycol, butylhydroxy toluene, disodium ethylenediamine tetraacetic acid, and citric acid (or tartaric acid or succinic acid) were added in sequence to each preparation container, and purified water was added so that the total weight of the solution became 100 wt%, and then filtered through a 0.45 μm filter to prepare a transparent solution. Each of the above manufactured samples was added at 10 ml per 20 ml vial and stored in a low-temperature freezer at -15°C for 2 weeks. The crystal and precipitate formation status of each sample was observed with the naked eye at room temperature (25°C), and the results are shown in Table 13.
