描述 | MZP-54 is a PROTAC targeting on BET, consist of a warhead I-BET726 (BET bromodomain inhibitor) linked to a VHL ligand VH032. It exhibited affinity to the Brd4BD2 and VHL-EloC-EloB protein with Kd values of 4nM and 105nM, respectively. Treatment with 50nM MZP-54 for 4h led to degradation of Brd4 by 87%, accompanied with the downregulation of c-MYC by 73% in MV4;11 cells. A dose-dependent antiproliferative effect on MV4;11 treated with MZP-54 at various concentration could be observed post 48h. A further assay showed that MZP-54 exhibited potency to depletion of Brd4 short, Brd4 long, Brd3 and Brd2 with pDC50/Dmax (%) values of 8.1/98, 7.6/95, 7.3/91 and −/43, respectively, in HeLa cells post 24-hour treatment. It exhibited anti-proliferative potency against MV4;11 cells and HL60 cells with pEC50/ Emax(%) values of 7.31/94.2 and 6.57 and 98.3, respectively, post 48h[1]. |
