Description

Pharmaceutical composition for preventing or treating skin diseases containing a calcineurin inhibitor

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

[0002] Psoriasis is a common chronic inflammatory skin disease that affects 2-3% of the global population and significantly reduces the quality of life of those affected. Psoriasis is a non-contagious, chronic autoimmune skin disease characterized by erythema and thickening of the skin due to excessive keratinization. Psoriasis is a chronic autoimmune disease that occurs when the immune system, which should be protecting against external microorganisms or irritants, instead attacks the skin itself.

[0003] Numerous studies have shown that the pathological factors of psoriasis are linked to immune system abnormalities. Currently, molecular biological mediators known to induce an excessive immune response include the inflammatory cytokines 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.

[0004] Meanwhile, atopic dermatitis is a chronic, intractable inflammatory skin disease characterized by itching, skin 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 skin barrier damage. The movement of these inflammatory cells is regulated by the interaction between chemokines and chemokine receptors.

[0005] And, when Thymic Stromal Lymphopoietin (TSLP) is secreted in the body, Th2 cells are activated and release 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. Bacteria that cause inflammatory skin diseases include Staphylococcus aureus, Candida albicans, and Malassezia sympodialis.

[0006] 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.) have been widely reported as side effects of drug therapy for the treatment of psoriasis and atopic dermatitis.

[0007] Therefore, there is an urgent need for a treatment for psoriasis and atopic dermatitis that suppresses itching, prevents infection from various pathogens, effectively restores damaged skin barriers, and has no side effects.

[0008] The present inventor has made diligent efforts to develop a pharmaceutical composition that, compared to existing single-component calcineurin inhibitor preparations, 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 against inflammatory cytokines that cause psoriasis and atopic dermatitis, and has thus completed the present invention.

Furthermore, octenidine dihydrochloride exhibits excellent anti-inflammatory properties by inhibiting Langerhans gland cell activation and suppressing the secretion of inflammatory cytokines.

[0079] 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.

[0080] 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.

[0081] 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 a calcineurin inhibitory component, and can significantly improve the effect of preventing and treating inflammatory skin diseases.

[0126] Test Example 1. Susceptibility Test for Antibacterial Activity Evaluation

[0127] Typically, clinical treatment outcomes can be predicted through antimicrobial susceptibility testing. The test strains for susceptibility testing for antimicrobial activity evaluation are Staphylococcus aureus, Candida albicans, and Malassezia sympodialis, which are causative agents of atopic dermatitis and psoriasis. To evaluate antimicrobial activity against the three microorganisms mentioned above, this experiment was conducted using the tube dilution technique. Antimicrobial activity evaluation was performed by determining the minimum growth inhibitory concentration (MIC) for each microorganism. 90 : The results of comparing Control Examples 1 to 2 and Manufacturing Examples 1 to 8 as Minimum Inhibitory Concentration (MIC) are as shown in Tables 3 and 4 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.

[0128] 1) Pre-culture of test bacteria

[0129] ① Staphylococcus aureus: Inoculated onto Tryptic Soy Agar (TSA) medium and cultured at 35±2℃ for 16 to 24 hours.

[0130] ②Candida albicans, Malassezia sympodialis: Inoculated onto Sabouraud Dextrose Agar (SDA) medium and cultured at 35±2℃ for 20 to 24 hours.

[0131] 2) Preparation of test bacterial solution and spore suspension

[0132] ① Staphylococcus aureus: 1×10 6The solution was diluted in Cation-Adjusted Muller-Hinton Broth (CAMHB) medium to CFU / ml and used as a test bacterial solution.

[0133] ② Candida 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 (RPMI 1640, Gibco), 5.0 × 10 2 ~2.5×10 3 A spore suspension of CFU / ml was prepared and used as a test bacterial solution.

[0134] 3) Inoculation of test bacteria solution

[0135] 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 1-2, Preparation Examples 1-8) on CAMHB medium was used as a negative control group, and a tube containing 1 ml of the solution (Control Examples 1-2, Preparation Examples 1-8) 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.

[0136] 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 1-2, Preparation Examples 1-8) 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 1-2, Preparation Examples 1-8) 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 24-48 hours.

[0137] 4) Judging the results

[0138] After incubation, the minimum concentration at which no bacterial growth occurred was considered the minimum growth inhibitory concentration.

[0141] As can be seen from the results in Tables 3 and 4 above, the compositions of Preparation Examples 1 to 8 showed significantly increased antibacterial activity against Staphylococcus aureus, Candida albicans, and Malassezia symphodialis compared to Control Examples 1 to 2 that did not contain octenidine dihydrochloride. The antibacterial activity of Preparation Examples 1 to 4 was 2.6 to 5.6 times higher than that of Control Example 1 against Staphylococcus aureus, 3.2 to 6.3 times higher than that of Candida albicans, and 2.9 to 5.8 times higher than that of Malassezia symphodialis. The antibacterial activity of Preparation Examples 5 to 8 was 2.8 to 5.4 times higher than that of Control Example 2 against Staphylococcus aureus, 2.8 to 5.8 times higher than that of Candida albicans, and 3.1 to 5.1 times higher than that of Malassezia symphodialis. Therefore, the pharmaceutical compositions according to Manufacturing Examples 1 to 8 show good sensitivity test results against the causative agent of psoriasis and atopic dermatitis, and thus, it can be predicted that they will show excellent clinical treatment results.

[0142] Test Example 2. Storage Stability Evaluation

[0143] Each sample from Control Examples 1 to 2 and Manufacturing Examples 1 to 8 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 5 below.

[0145] As described in Table 5, the solutions of Preparation Examples 1 to 8 showed improved stability compared to Control Examples 1 to 2 that did not contain octenidine dihydrochloride. In the 500 nm absorbance measured after 4 weeks, Control Example 1 showed an absorbance increase of about 7%, whereas Preparation Examples 1 to 4 showed an absorbance increase of about 2%, Control Example 2 showed an absorbance increase of about 8%, whereas Preparation Examples 5 to 8 showed an absorbance increase of about 2 to 3%. Therefore, it can be seen that the compositions of Preparation Examples 1 to 8 showed superior stability compared to Control Examples 1 to 2 even after 4 weeks at 45°C.

[0146] Test Example 3. Evaluation of the ability to suppress inflammatory cytokines

[0147] The ability to suppress inflammatory cytokines for Control Examples 1 to 2 and Manufacturing Examples 1 to 8 was evaluated using the method described below.

[0148] (1) Ability to suppress cytotoxicity and inflammatory cytokines in keratinocytes

[0149] 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.

[0150] ① Cytotoxicity assessment (MTT Assay)

[0151] 1×10 cultured keratinocytes 6100 μl was dispensed into a 96-well plate at cells / ml and cultured for 24 hours under 37°C, 5% CO₂ conditions. The medium was removed, and 100 μl of DMEM medium and 100 μl of sample (control examples 1-2, preparation examples 1-8) 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 6.

[0152] * Cell viability (%) = (absorbance of sample-added group / absorbance of sample-free group) × 100

[0153] ② Ability to suppress inflammatory cytokines

[0154] 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 1-2 and Preparation Examples 1-8 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).

[0155] 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 6.

[0157] As can be seen from the results in Table 6, the compositions of Preparation Examples 1 to 8 showed significantly increased inhibitory effects on IL-17A and IL-23 compared to Control Examples 1 to 2 that did not contain octenidine dihydrochloride. The inhibitory effects of Preparation Examples 1 to 4 were 2.8 to 4.8 times higher for IL-17A and 2.9 to 4.5 times higher for IL-23 than Control Example 1. The inhibitory effects of Preparation Examples 5 to 8 were 3.1 to 4.6 times higher for IL-17A and 2.8 to 5.2 times higher for IL-23 than Control Example 2. Therefore, since the pharmaceutical compositions of Preparation Examples 1 to 8 showed good inhibitory effects on the major cytokines (IL-17A, IL-23) that cause psoriasis, it can be predicted that they will also show excellent therapeutic results clinically.

[0158] (2) Ability to suppress cytotoxicity and inflammatory cytokines in mast cells

[0159] 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.

[0161] Cultured mast cells were 1×10 6100 μl was dispensed into a 96-well plate at cells / ml and cultured for 24 hours under 37°C, 5% CO₂ conditions. The medium was removed, and 100 μl of DMEM medium and 100 μl of sample (control examples 1-2, preparation examples 1-8) 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 (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 7.

[0162] * Cell viability (%) = (absorbance of sample-added group / absorbance of sample-free group) × 100

[0163] ② Ability to suppress inflammatory cytokines

[0164] Mast cells were seeded at 5×10 per well in a 96-well plate. 5After 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 2 and Manufacturing Examples 1 to 8 were treated at a concentration of 100 μg / ml each, and then cultured for 8 hours in an incubator at 37°C and 5% CO2 conditions. 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 7.

[0166] As can be seen from the results in Table 7, the compositions of Preparation Examples 1 to 8 showed significantly increased inhibitory effects on IL-4 and IL-13 compared to Control Examples 1 to 2 that did not contain octenidine dihydrochloride. The inhibitory effects of Preparation Examples 1 to 4 were 3.1 to 5.3 times higher for IL-4 and 2.5 to 4.5 times higher for IL-13 than Control Example 1. The inhibitory effects of Preparation Examples 5 to 8 were 3.1 to 5.7 times higher for IL-4 and 3 to 5.2 times higher for IL-13 than Control Example 2. Therefore, the pharmaceutical compositions of Preparation Examples 1 to 8 showed good inhibitory effects on the major cytokines (IL-4, IL-13) that cause atopic dermatitis, and thus, it can be expected to show excellent therapeutic results clinically as well. Figure 1 is a graph showing the results of the inhibitory effects experiment on IL-17A and IL-23 according to Control Example 1 and Preparation 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 experiment on the inhibitory effect 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.

[0167] Test Example 4. Evaluation of the ability to suppress crystal precipitation during low-temperature storage
