Establishment and application of a method for screening the therapeutic drugs of ethanol-induced liver injury based on cellular metabonomics.

A drug-screening method to test the capacity of drugs to protect against ethanol-induced liver injury based on cellular metabonomics was established and applied in this study. It screens for the ability to protect against ethanol-induced liver injury by considering changes in the cellular metabolites of human normal liver L-02 cells subjected to ethanol treatment. This method considers cellular metabolites as the main analytical index, principal component analysis and orthogonal partial least squares discriminant analysis as the main multi- and megavariate data analysis methods, and vitamin C as the standard substance to determine the ability to protect against ethanol-induced liver injury. Ability to protect against ethanol-induced liver injury unit = [190 - 50× (14.318 - 10 × Y predictive value)1/2 ] × ability 1 μg/mL vitamin C. Olive leaf extract, Lycium barbarum L extract and fish roe peptide were screened using the established methods. Olive leaf OP phase had the strongest ability to protect against ethanol-induced liver injury, at 81.88. The value for L. barbarum L was 37.56. The fish roe peptide water phase was 63.07. All three have the ability to protect against ethanol-induced liver injury. The drug-screening method for ability to protect against ethanol-induced liver injury based on cell metabonomics is a fast, accurate and effective method for quantitative detection of ability to protect against ethanol-induced liver injury.
