MS177

MS 177 (MS-177) is a potent and selective EZH2 degarder (PROTAC) based on EZH2 inhibitor C24 with CRBN ligand pomalidomide with DC50 of 0.2 uM in EOL-1 cells.MS177 effectively degraded cellular EZH2-PRC2, suppressed global H3K27me3 in leukaemia cells.MS177 exhibited half-maximal degradation concentration (DC50) values of 0.2 ± 0.1 μM and 1.5 ± 0.2 μM, and maximum degradation (Dmax) values of 82% and 68%, respectively, in EOL-1 and MV4; 11 cells.MS177 efficiently suppresses EZH2-PRC2 functions, also efficiently induces Myc degradation in cancer cells, suppresses EZH2-PRC2 functions.MS177 efficiently induces leukaemia cell growth inhibition, apoptosis and cell cycle progression arrest, which is more effective than EZH2 inhibitors. MS177 (i.p. injection, 50-1 g/kg) represses AML growth without apparent toxicity in PDX models.
