PURPOSE: A pharmaceutical composition for preventing or treating aging-related diseases and a method for screening a binding inhibitor are provided to effectively treat or prevent diseases caused by progerin and to specifically select a drug which suppresses binding between progerin and lamin A. CONSTITUTION: A compound of chemical formula 1 or 2 or a pharmaceutically acceptable salt thereof is provided. A pharmaceutical composition for preventing or treating aging-related diseases contains the compound of chemical formula 1 or 2 or a pharmaceutically acceptable salt thereof as an active ingredient. A method for screening a therapeutic agent for treating aging-related diseases comprises the step of selecting candidate drugs which suppress binding between progerin and lamin A.
Abstract:
PURPOSE: A production method of an environment-friendly edible film is provided to mix a specific plasticizer with an excellent physical property and a cross-linking agent with persimmon skin for producing the edible film. CONSTITUTION: Persimmon skin is finely cut, and a persimmon skin solution is produced. A plasticizer and a cross-linking agent are mixed with the persimmon skin solution to obtain a persimmon skin film solution. The persimmon skin solution is coated into a thickness of 0.1 mm, and dried. The cutting step is performed by using an autoclave, a homogenizer, and a high pressure homogenizer. 3-10 wt% of persimmon skin is added for the total amount of edible film. The persimmon skin solution is produced by the following steps: processing the persimmon skin using the autoclave at 100-140°C and in the pressure of 0.05-0.15 MPa for 15 minutes; and homogenizing the processed persimmon skin using the homogenizer for 5-30 minutes, and high pressure homogenizing the persimmon skin under 10,000-15,000 psi for 1-10 times. [Reference numerals] (AA) Collect persimmon skins produced during processing persimmons; (BB) Wash the persimmon skins with water and dry at 50°C for 48 hours; (CC) Pulverize the dried skins and select the powder of persimmon skins under the size of 80 mesh; (DD) Produce 5 weight% of a persimmon skin solution; (EE) Process the solution in a sterilizer at 121°C, 0.1 MPa for 15 minutes; (FF) Homogenize the solution in a homogenizer at 20,000 rpm; (GG) High-pressure Homogenize the solution in a high-pressure homogenizer at 13,000 psi for 20 minutes; (HH) Remove bubbles; (II) Add 1.5 weight% cane sugar; (JJ) Add 0.01 weight% of cinnamon aldehyde; (KK) Stir the solution for 1 hour; (LL) Divide the solution at the thickness of 0.1 mm on a module; (MM) Dry at room temperature; (NN) Edible persimmon skin film
