[0079] In the preparation process of the health-care functional food composition, the amount of the compound represented by Chemical Formula 1 or its pharmaceutically acceptable salt added to the food can be adjusted as needed, but relative to 100% by weight For foods, the above-mentioned addition amount is preferably 1% by weight to 15% by weight, but is not limited thereto.
[0080] As another embodiment, the present invention provides a method for inhibiting TSLP secretion, which includes the step of administering the above-mentioned composition to an individual.
[0081] The term "administration" used in the present invention refers to providing the prescribed substance to the patient by any suitable method. For the administration route of the composition of the present invention, as long as it can reach the target tissue, any usual administration method can be adopted. way. Examples include skin application, intraperitoneal administration, intravenous administration, int...
Embodiment 1
[0087] Example 1: Evaluation of TSLP secretion inhibitory properties of human epidermal keratinocytes
[0088] Human epidermal keratinocytes were treated with rhein (Rhein), which is a compound represented by Chemical Formula 1 of the present invention, and cultured, and the TSLP secretion inhibitory effect was confirmed.
[0089] Each well of a 24-well plate was injected with 1×10 human epidermal keratinocytes. 4 After the individual cells were allowed to attach, they were cultured for 4 days, and when they reached more than 90%, they were replaced with a new culture solution added with calcium chloride at a concentration of 1.4 mM, and then cultured for another 2 days to induce cell differentiation. To induce TSLP secretion in differentiated cells, treatment with polyI:C 20 μg / mL was performed. Then, they were treated with rhein at 0.5 μg / mL, 1 μg / mL and 2 μg / mL respectively, and after 24 hours, the cell culture fluid was taken, and the concentration of TSLP was determined ...
Embodiment 2
[0091] Example 2: Evaluation of the cytotoxicity of the compound rhein represented by Chemical Formula 1
[0092] In order to analyze the cytotoxicity of rhein, after the treatment with each concentrated rhein, the viability of the cells was confirmed using a spectrophotometer.
[0093] Each well of a 24-well plate was injected with 1×10 human epidermal keratinocytes. 4 After the individual cells were allowed to attach, they were cultured for 4 days, and when they reached more than 90%, they were replaced with a new culture solution added with calcium chloride at a concentration of 1.4 mM, and then cultured for another 2 days to induce cell differentiation. Then, polyI:C was treated at 20 μg / mL, and rhein was treated with 0.5 μg / mL, 1 μg / mL, and 2 μg / mL, respectively, and cultured for 24 hours. After 24 hours, remove the medium, add 200 μl of medium and 20 μl of CCK8 solution to each well, and incubate at 37°C, CO 2 Incubate in ambient medium for 20 minutes, then measure abs...
