GNE-987 is a PROTAC connected by ligands for von Hippel-Lindau and BRD4 . GNE-987 exhibits picomolar cell BRD4 degradation activity ( DC 50 =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 ( IC 50 =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) In Vitro GNE-987 inhibits EOL-1 and HL-60 cell viability with IC 50 s of 0.02 and 0.03 nM, respectively, and inhibits MYC expression with an IC 50 of 0.03 nM. GNE-987 (0.1-10 nM; 5 hours) degrades the BRD2 and BRD3 BET family proteins. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
