- a method of treating a wound comprising administering to a subject an effective amount of.
- the description of the above-mentioned “composition according to the present disclosure” can be cited.
- the subject to be administered is not particularly limited as long as it requires wound treatment.
- Example 1 Diabetic mice induced by compound A (N-( ⁇ 2-[4-(difluoromethoxy)-3-(propan-2-yloxy)phenyl]-1,3-oxazol-4-yl ⁇ methyl)-2-ethoxybenzamide) Compound A or Crisaborole was administered to db/db mice, a spontaneous diabetes model, for 10 days, and the effect on wound healing was examined by analyzing the wound area.
- test method Before the start of the test, db/db mice were divided into groups based on blood HbA1c concentration, and their hair was shaved from the back to the abdomen. On the first day of the test, two circular defective wounds were created by punching out the dorsal skin using a biopsy trepan ( ⁇ 6 mm) under isoflurane anesthesia. After taking a photograph of the defect, an ointment formulation containing the test substance (base [white petrolatum containing 30% medium-chain fatty acid triglyceride], Compound A or Crisaborole) was applied, and the defect was covered with a covering material (Tegaderm, 3M). From the day after the defect was created, the covering material was removed, the defect was photographed (once every 2 days), the test substance was administered, and the covering material was repeated (once a day for 10 days).
- base white petrolatum containing 30% medium-chain fatty acid triglyceride
- the defect wound area gradually decreased from the 4th day onward, indicating that healing had begun, but in the Compound A group (1%, 2%), the defect area rapidly decreased from the 2nd day onwards. It was confirmed that the area had decreased and healing had begun, and a healing promoting effect was confirmed compared to the base application group over the experimental period (p ⁇ 0.01).
- Crisaborole which is the same PDE4 inhibitor, it was confirmed that the defect area increased on the second day (2% group) and then gradually decreased from the fourth day, compared to the base-applied group. No significant healing promoting effect was observed.
- Example 2 Effect of Compound A on epidermal cells via dermal fibroblasts The effect of Compound A on epidermal cells via dermal fibroblasts was evaluated. Normal human epidermal keratinocytes (NHEK, Kurashiki Boseki Co., Ltd.) and normal human dermal fibroblasts (NHDF, Kurashiki Boseki Co., Ltd.) were used as the epidermal cells and skin fibroblasts used in this evaluation system. In addition, dexamethasone, an anti-inflammatory drug, was used as a reference compound.
- DMEM Dulbecco's Modified Eagle Medium
- FBS fetal bovine serum
- the compound solution was prepared by mixing dimethyl sulfoxide or a compound (compound A or dexamethasone) dissolved in dimethyl sulfoxide with normal human epidermal keratinocyte basal medium (HuMedia-KB2, Kurashiki Boseki Co., Ltd.) ( The final concentration of dimethyl sulfoxide was 0.1% [v/v]). After 24 hours of culture, the culture supernatant (conditioned medium) was collected.
- Epidermal cells (6 ⁇ 10 5 cells/mL) suspended in HuMedia-KB2 were seeded at 100 ⁇ L/well on an ImageLock 96-well plate (Sartorius Corporation) coated with type I collagen, and cultured for 4 hours. Each well was scratched using the Wound MakerTM tool (Sartorius, Inc.) to create an initial scratch wound area. After washing each well with HuMedia-KB2, the above compound solution or Conditioned Medium was added and cultured for 18 hours. During culture, images were acquired over time using Incucyte (trademark) S3 (Sartorius Corporation). The proportion covered by cells (Wound Confluence [%]) in the initial scratch wound area was calculated by image analysis using the Scratch Wound Cell Migration Software Module (Sartorius Corporation).
- Example 3 Effect of compound A on a wound model using rats with oral ulcers (test method) Oral ulcers were induced by cauterization in male rats (SD rats) as follows. Specifically, a normally bred rat was anesthetized with isoflurane inhalation anesthesia, placed on its back, and a monopolar tip with a diameter of 2 mm was applied to the center of the left oral mucosa while opening the upper and lower jaws using a thoracotomy device to obtain a visual field. Intraoral ulcers were induced by cauterizing in a circular shape (3-4 mm in diameter) at a power setting of 20 for approximately 10-20 seconds. After cauterization, the animals were returned to the breeding cage and allowed to awaken naturally.
- the day of induction of oral ulcer was defined as the start date (Day 0). Two days after the induction of oral ulcer (Day 2), the mice were divided into groups based on body weight using a stratified random sampling method. Starting 3 days after inducing oral ulcers by cautery (Day 3), administer ointment preparations or ointment bases containing 1% by mass of the test substance twice a day (around 8:00 and 16:00) for 5 days. It was administered intraorally at a dose of 0.05 mL for 5 days. (Compound A 1% was prepared using Moiselt® Ointment 1%.
- Crisaborole 1% was prepared using a formulation in which Compound A in Moiselt® Ointment 1% was replaced with Crisaborole.) Specifically. Rats were anesthetized by isoflurane inhalation, placed in the left lateral position, and the ointment formulation was administered to the left cheek where an ulcer had been created with the oral cavity opened using forceps or a thoracotomy device.
- Example 4 Effect of Compound A on a wound model using corneal-wounded rats (test method) Corneal wounds were induced in male rats (SD rats) as follows. The day before the start of the study, subjects were divided into groups based on body weight using a stratified random sampling method. Normally bred rats were anesthetized with isoflurane and the surface of the eye was anesthetized using Benoxil eye drops, and a nonwoven fabric (3 mm diameter) impregnated with 1-heptanol was placed on the central cornea and allowed to stand for 30 seconds. Thereafter, the surface of the eye was washed with physiological saline, and the corneal epithelium was carefully removed by scraping with a cotton swab to create a corneal defect.
- test method Corneal wounds were induced in male rats (SD rats) as follows. The day before the start of the study, subjects were divided into groups based on body weight using a stratified random sampling method. Normally bred rats were anesthetized
- Example 5 Effect of Compound A on corneal epithelial cells via keratocytes The effect of Compound A on corneal epithelial cells via keratocytes was evaluated.
- corneal epithelial cells and corneal stromal cells used in this evaluation system normal human corneal epithelial cells (HCEC-2, Kurashiki Boseki Co., Ltd.) and normal human corneal stromal cells (HK, Cosmo Bio Co., Ltd.) were used.
- HCEC-2 normal human corneal epithelial cells
- HK Cosmo Bio Co., Ltd.
- Corneal epithelial cells (6 ⁇ 10 5 cells/mL) suspended in OcuLife BM were seeded at 100 ⁇ L/well on an ImageLock 96-well plate (Sartorius Corporation) coated with type I collagen, and cultured for 4 hours. Each well was scratched using the Wound MakerTM tool (Sartorius, Inc.) to create an initial scratch wound area. After washing each well with OcuLife BM, the above compound solution or Conditioned Medium was added and cultured for 20 hours. During culture, images were acquired over time using Incucyte (trademark) SX5 (Sartorius Corporation). The proportion covered by cells (Wound Confluence [%]) in the initial scratch wound area was calculated by image analysis using the Scratch Wound Cell Migration Software Module (Sartorius Corporation).
- corneal epithelial cells Migration of corneal epithelial cells was induced by the addition of conditioned medium derived from keratocytes. Since Compound A promoted the migration of corneal epithelial cells via corneal stromal cells, it is suggested that Compound A promotes corneal epithelial formation.
