Certain embodiments describe antiviral compounds and related methods of using such compounds.

Disclosed are 1,3-Dioxoindene derivatives, pharmaceutically acceptable salts thereof or enantiomers, a preparation method thereof, and a pharmaceutical composition for the prevention or treatment of viral diseases, comprising the same as an active ingredient. The 1,3-Dioxoindene derivatives have excellent inhibitory activity against picornaviruses including coxsackie-, entero-, echo-, Polio-, and rhinoviruses, as well as exhibiting low cytotoxicity, so that they can be useful as an active ingredient of a pharmaceutical composition for the prevention or treatment of viral diseases including poliomyelitis, paralysis, acute hemorrhagic conjunctivitis, viral meningitis, hand-foot-and-mouth disease, vesicular disease, hepatitis A, myositis, myocarditis, pancreatitis, diabetes, epidemic myalgia, encephalitis, cold, herpangina, foot-and-mouth disease, asthma, chronic obstructive pulmonary disease, pneumonia, sinusitis or otitis media.

This invention relates to a method to modulate exogenous gene expression in which an ecdysone receptor complex comprising: a DNA binding domain; a ligand binding domain; a transactivation domain; and a ligand is contacted with a DNA construct comprising: the exogenous gene and a response element; wherein the exogenous gene is under the control of the response element and binding of the DNA binding domain to the response element in the presence of the ligand results in activation or suppression of the gene. The ligands comprise a class of ketones.
