Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a composition containing glycyrrhetinic acid, and cetylpyridinium chloride and / or isopropylmethylphenol, and uses thereof. [Background technology]
[0002] As periodontal disease progresses, the alveolar bone, which supports the teeth, is destroyed (bone resorption), leading to tooth loss. Alveolar bone resorption occurs through the breakdown of bone tissue by osteoclasts, and this occurs due to excessive differentiation of osteoclast precursor cells into osteoclasts as periodontal disease progresses.
[0003] Glycyrrhetinic acid has been reported to have inhibitory effects on osteoclast differentiation and alveolar bone resorption (Non-Patent Documents 1 and 2, Patent Document 1), and is widely used in oral compositions such as toothpaste. [Prior art documents] [Patent documents]

[Example]
[0048] The contents of the present disclosure will be specifically explained using the following experimental examples. However, the present disclosure is not limited to these examples. In the following, unless otherwise specified, experiments were performed under atmospheric pressure and room temperature conditions. Furthermore, unless otherwise specified, "%" indicating concentration means "mass-to-volume concentration (w / v)%."
[0049] (1) Permeabilization The materials were prepared by dissolving β-glycyrrhetinic acid (GR), cetylpyridinium chloride (CPC), and isopropylmethylphenol (IPMP) in PBS at the specified concentrations (ppm). A 3D gingival epithelial model (SkinEthic™ HGE) was placed in a 12-well plate with 1500 μL of PBS applied. 300 μL of the prepared materials were applied to the 3D model and incubated at 37°C and 5% CO2 for 24 hours. Afterwards, the permeation samples (PBS in 12 wells) were collected.
[0050] (2) Osteoclast differentiation (2-1) RAW264 osteoclast precursor cells were seeded onto a 96-well plate at 5,000 cells per well. The cells were cultured at 37°C in a 5% CO environment for 4 hours to allow the cells to adhere to the plate. (2-2) The permeabilized samples collected in (1) were supplemented with 1 / 5 the volume of 5x concentrated culture medium and RANKL at 250 ng / mL. The positive control was treated with PBS instead of the permeabilized samples from (1), and the negative control was treated with PBS without RANKL. (2-3) The medium was removed from the cells adhered in (2-1), and 100 μL of the sample prepared in (2-2) was added and cultured for 5 days. (2-4) The culture supernatant was collected and TRAP (a specific enzyme for osteoclasts) activity was measured. The osteoclast differentiation rate was calculated by setting the negative control group as 0% and the positive control group as 100%. The results are shown in Figure 1.
[0051] (3) Measurement of βGR levels The amount of βGR in the samples collected in (1) was determined by a known quantitative method using liquid chromatography. The results are shown in Figure 2.
[0052] As shown in Figure 1, it was confirmed that the addition of CPC or IPMP in combination with GR at 125 ppm (0.0125%) or 500 ppm (0.05%) more effectively inhibited osteoclast differentiation than the addition of GR alone at 250 ppm (0.025%) or 500 ppm (0.05%). As shown in Figure 2, the combination of GR with CPC or IPMP did not result in any difference in the amount of GR in the transmission sample.
