PHARMACEUTICAL COMPOSITION FOR SUPPRESSING DNA METHYLTRANSFERASE, CONTAINING ARYLOXYACETYL-BASED COMPOUNDS AS ACTIVE INGREDIENTS

The present invention relates to a pharmaceutical composition for suppressing DNA methyltransferase, containing the aryloxyacetyl-based compounds expressed in chemical formula 1 as active ingredients. The composition of the present invention can be used as a therapeutic agent for tumors, neurological brain diseases, hematologic diseases, and epigenetic diseases caused by DNA hypermethylation. Further, the present invention provides uses of aryloxyacetyl-based compounds expressed in chemical formula (1) mentioned below or pharmaceutically acceptable salts thereof to produce a DNA methyltransferase inhibitor or a DNA methylation inhibitor. The present invention provides a method for treating diseases caused by DNA hypermethylation by administering aryloxyacetyl-based compounds (LW6) expressed in chemical formula 1, or pharmaceutically acceptable salts thereof, to mammals (including humans) that require DNA methytransferase inhibition or DNA methylation inhibition.
