Description: YM281 is a proteolysis-target chimera (PROTAC)-based EZH2 degrader. YM281 induced robust cell viability inhibition in diffuse large B-cell lymphoma (DLBCL) and other subtypes of lymphomas, outperforming a clinically used EZH2 inhibitor EPZ6438 (tazemetostat) that was only effective against DLBCL. The EZH2 degrader displayed promising antitumor activities in lymphoma xenografts and patient-derived primary.
