Background
MZP-54 is a selective degrader of BRD3/4 based on PROTAC technology, with a Kd of 4 nM for Brd4BD2.
MZP-54 is a selective degrader of BRD3/4 based on PROTAC technology, with a Kd of 4 nM for Brd4BD2. MZP-54 binds to VHL-EloC-EloB protein (VCB) with a Kd of 105 ± 24 nM. MZP-54 shows an inhibitory activity against MV4;11 and HL60 cells, with pEC50s of 7.08 ± 0.05 and 6.37 ± 0.03, respectively. MZP-54 also exhibits high depletion of cMyc levels[1].

Protocol
Cell experiment: | MV4;11 or HL60 cells are incubated with MZP-54 at the desired concentration for 48 h on a clear-bottom 384-well plate. Cells are kept in RPMI medium supplemented with 10% FBS, l-glutamine, penicillin, and streptomycin. Initial cell density is 3 × 105 per mL. Cells are treated with various concentrations of MZP-54 or 0.05% DMSO. After treatment, cell viability is measured with cell viability assay kit. Signal is recorded. Data are analyzed with Graphpad Prism software to obtain EC50 values of each MZP-54[1]. |
