Biological Activity

TO-1187 is a potent, selective, cereblon (CRBN)-based HDAC6 PROTAC degrader with DC50 of 5.81 nM in MM.1S cells (6 h), Dmax of 94%.
TO-1187 exhibits no cellular degradation of other HDACs.
TO-1187 does not impact the abundance of well-known CRBN neosubstrates, like IKZF1, IKZF3, CK1α, SALL4, and GSPT1.
TO-1187 efficiently degrades HDAC6 in mouse tissues, measured 6 h after intravenous injection.
