EHMT2-IN-1 is primarily used in research settings to study its potential as an inhibitor of the EHMT2 enzyme, which plays a role in epigenetic regulation. By inhibiting EHMT2, this compound helps researchers understand the enzyme's function in gene expression and its impact on diseases such as cancer. It is particularly valuable in exploring therapeutic strategies targeting epigenetic modifications, as EHMT2 is involved in histone methylation, a key process in controlling gene activity. Its application extends to preclinical studies aimed at developing treatments for conditions linked to abnormal epigenetic regulation.
