GNE-274 is a non-degrading estrogen receptor α (ERα/ESR1) modulator structurally similar to GDC-0927 (HY-111484). GNE-274 competes for binding to the ligand-binding domain of ERα and induces a coregulator-binding conformation similar to that of antagonists, yet retains partial agonistic transcriptional activity and does not promote ERα turnover. GNE-274 effectively inhibits E2-stimulated proliferation of ER-positive, HER2-negative breast cancer cells. GNE-274 promotes the recruitment of ERα to the nucleus and chromatin, increases chromatin accessibility, while largely maintaining the intranuclear mobility of ERα. GNE-274 can be used in research on ER-positive breast cancer and ERα transcriptional dynamics.
