Abstract:
PURPOSE: Provided are an extract of Acer okamotoanum having anti-oxidant activity and a pharmaceutical composition comprising the same as an active ingredient. The extract prevents and treats diseases caused by oxygen free radicals, preserves foods and prevents skin aging caused by oxidative damage. CONSTITUTION: The extract of Acer okamotoanum is obtained by using an organic solvent selected from the group consisting of alcohol, ethylacetate, dichloromethane and acetone as an extracting solvent, and has anti-oxidant activity. The extract contains a compound selected form the group consisting of compounds represented by the formulae 1-9, as an active ingredient.
Abstract:
The present invention relates to 4-(phenylamino)-[1,4]dioxano[2,3-g]quinazoline derivatives which inhibit tyrosine kinase of epidermal growth factor receptor(EGFR), and pharmaceutically acceptable salts, hydrates and solvates thereof, and a process for preparing the same. Since 4-(phenylamino)-[1,4]dioxano[2,3-g]quinazoline derivatives of the invention have a high solubility in water and inhibit the activity of EGFR tyrosine kinase and the growth of cancer cells, they can be practically applied in the treatment of overproliferation-associated diseases such as cancer.
Abstract:
PURPOSE: A COD(chemical oxygen demand) reducing technology for leachate from a reclamation site using biological treatment is provided to greatly reduce COD by using bacteria producing lignin decomposition and/or oxidation enzyme. CONSTITUTION: Using bacteria having lignin decomposing enzyme or oxidizing enzyme like monoxidase or dioxidase, lignin and cyclic compounds containing halogen, which are hardly decomposed under normal condition, are easily decomposed to reduce COD. The treated bacteria grow well without adding no nutrient in the leachate. Intake and decomposition by the bacteria reduce COD value and lower nutrients in the leachate.
Abstract:
The present invention relates to thienopyrimidinone derivatives as antagonists that act on metabotropic glutamate receptor subtype 1. The thienopyrimidinone derivatives show pharmacological activity against metabotropic glutamate receptor-related diseases, including pain, such as neuropathic pain and migraine, psychiatric diseases, such as anxiety disorder and schizophrenia, urinary incontinence, and neurodegenerative diseases, such as Parkinson′s disease and Alzheimer′s disease. The present invention also relates to methods for preparing the thienopyrimidinone derivatives, and pharmaceutical compositions containing the thienopyrimidinone derivatives as active ingredients.
