Abstract:
PURPOSE: A 1,3-dioxoindene derivative capable of treating enterovirus or rhinovirus, a pharmaceutically acceptable salt or an optical isomer, a manufacturing method thereof, and a pharmaceutical composition for antivirus containing the same are provided to lower cytotoxin. CONSTITUTION: A 1,3-dioxoindene derivative capable of treating enterovirus or rhinovirus, a pharmaceutically acceptable salt or an optical isomer are represented by chemical formula 1. A manufacturing method of the 1,3- dioxo indene derivative comprises the following step: obtaining a compound of chemical formula 1a by acylating or alkylating the compound of chemical formula 2 under base and solvent. A pharmaceutical composition for preventing or treating the viral disease contains the 1,3- dioxo indene derivative represented by the chemical formula 1, the pharmaceutically acceptable salt thereof or the optical isomer as an active ingredient.
Abstract:
The present invention relates to a novel compound, a pharmaceutically acceptable salt or an optical isomer thereof, a method for preparing the same, and a pharmaceutical composition for preventing or treating viral diseases containing the same as an active ingredient. According to the present invention, the novel compound not only has low cytotoxicity but also has excellent antiviral activity against picornavirus such as coxsackievirus, enterovirus, echovirus, poliovirus and rhinovirus, thereby being effectively used as a pharmaceutical composition for preventing or treating viral diseases, such as infantile paralysis, acute hemorrhagic conjunctivitis, viral meningitis, hand-foot-and-mouth diseas, vesicular disease, hepatitis A, myitis, myocarditis, pancreatitis, diabetes, epidemic myalgia, encephalitis, cold, herpangina, foot-and-mouth disease, asthma, chronic obstructive pulmonary disease, pneumonia, sinus infection, or otitis media.

Abstract:
PURPOSE: A pharmaceutical composition or a health food composition containing sulfur-containing extracellular polysaccharides p-KG03 is provided to prevent and treat influenza viral infection. CONSTITUTION: A pharmaceutical composition for preventing or treating influenza virus A infection contains sulfur-containing extracelullar p-KG03 as an active ingredient, isolated from Gyrodinium impudicum KG03(KCTC 10325BP). The optimal temperature and pH of extracellular polysaccharide p-KG03 is 25-30 deg.C. and pH 8-9. The composition contains an anti-influenza virus formulation such as zanmivir, oseltamivir, amandadine, rimantadine, or ribavirin. A health food composition for preventing or treating influenza viral infection contains sulfur-containing extracelullar p-KG03 as an active ingredient.
