GNE-987 is a highly active chimeric BET degrader. GNE-987 exhibits picomolar cell BRD4 degradation activity (DC50=0.03 nM for EOL-1 AML cell line). GNE-987 binds equipotently to the BD1 and BD2 bromodomains of BRD4 with low nanomolar affinities (IC50=4.7 and 4.4 nM, respectively). GNE-987 incorporates a potent BET binder/inhibitor, a VHL-binding fragment, and a ten methylene spacer moiety. GNE-987 can be used in PROTAC-Antibody Conjugate (PAC)[1].
GNE-987 inhibits EOL-1 and HL-60 cell viability with IC50s of 0.02 and 0.03 nM, respectively, and inhibits MYC expression with an IC50 of 0.03 nM[1]. GNE-987 (0.1-10 nM; 5 hours) degrades the BRD2 and BRD3 BET family proteins[1]. Western Blot Analysis[1] Cell Line: EOL-1 cells
