Indanone derivatives, pharmaceutically acceptable salts thereof or optical isomer thereof, preparation method thereof and pharmaceutical composition for prevention or treatment of the viral diseases containing the same as an active ingredient

摘要

The present invention relates to a novel indanone derivative, pharmaceutically acceptable salts or optical isomers thereof, a preparation method for same, and a pharmaceutical composition containing same as an active ingredient for preventing or treating viral diseases. The indanone derivatives according to the present invention not only have low cyto-toxicity, but can also demonstrate utility as pharmaceutical compositions for preventing or treating viral diseases such as:; polio, viral paralysis, acute hemorrhagic conjunctivitis, viral meningitis, hand-foot-mouth disease, blistering diseases, hepatitis A, myositis, myocarditis, pancreatitis, viral diabetes, epidemic myalgia, encephalitis, flu, herpes angina, foot-and-mouth disease, asthma, chronic obstructive pulmonary disease, pneumonia, sinusitis, otitis media, and the like, since excellent antiviral activity against picornaviruses such as Coxsackie virus, enterovirus, echovirus, polio virus, rhinovirus, and the like, have been demonstrated.
