Abstract

The present invention relates to a compound comprising an EZH2 inhibitor and an E3 ligase binder, and a pharmaceutical composition for preventing or treating EZH2-associated disease and a pharmaceutical composition for selective protein degradation containing the same as an active ingredient. Since the compound of the present invention can selectively degrade EZH2, it can be effectively used for the treatment of EZH2-related diseases and cancers, particularly, cancers in which EZH2 is overexpressed, and can be usefully used for the selective degradation of EZH2.
