EED226 is primarily utilized in the field of biomedical research, particularly in the study of epigenetic regulation. It functions as a potent and selective inhibitor of the Polycomb Repressive Complex 2 (PRC2), which plays a critical role in gene silencing through histone methylation. By inhibiting PRC2, EED226 is used to investigate the mechanisms of gene expression and its impact on cellular processes such as differentiation, proliferation, and cancer development. This compound is valuable in understanding the role of epigenetic modifications in diseases and in the development of potential therapeutic strategies targeting epigenetic pathways.
