PROTAC Mcl1 degrader-1 (compound C3), a proteolysis targeting chimera (PROTAC) based on Cereblon ligand, is a potently and selectively Mcl-1 (Bcl-2 family member) inhibitor with an IC50 of 0.78 μM. PROTAC Mcl1 degrader-1 inhibits Bcl-2 with an IC50 of 0.54 μM.In Vitro:PROTAC Mcl1 degrader-1 (compound C3) induces the ubiquitination and proteasomal degradation of Mcl-1 by introducing the E3 ligase cereblon (CRBN)-binding ligand pomalidomide to Mcl-1 inhibitor S1-6 with μM-range affinity.
PROTAC Mcl1 degrader-1 (0-10 μM; 0-24 h) induces selective depletion of Mcl-1 or Bcl-2 protein in HeLa cells in a time- and concentration-dependent manner.
PROTAC Mcl1 degrader-1 (0-2 μM; 24 h) shows cytotoxicity against H23 cells.
