Mcl1 Degrader-1
Mcl1 Degrader-1 is an autophagy-targeting chimera (AUTAC) that selectively degrades the Mcl1 protein. Mcl1 Degrader-1 mediates K63 ubiquitination of Mcl1 via TRAF6/UBC13, transports it to autolysosomes for degradation through p62/SQSTM1, and activates Beclin1-dependent autophagy. Mcl1 Degrader-1 can be used in studies related to multiple myeloma and non-small cell lung cancer.

Mcl-1 |
Mcl1 Degrader-1 (AUTAC) binds to Mcl1 selectively over Bcl2 and Bclxl[1].
Mcl1 Degrader-1 (100 nM-10 μM; 24-48 h) selectively degrades Mcl1 in a dose- and time-dependent manner in vitro in U266B1 cells, without degrading Bcl2 or Bclxl, while also activating autophagy[1].
Mcl1 Degrader-1 (5 μM; 24 h) requires autophagy to degrade Mcl1 in U266B1 cells[1].
Mcl1 Degrader-1 (0.1-10 μM; 24-72 h) reduces the viability and induces cell death of U266B1 and RPMI-8226 multiple myeloma cells in a time-dependent manner; its IC50 reaches 5 μM after 48 h of treatment in U266B1 cells[1].
Mcl1 Degrader-1 (10 μM; 24 h) dissociates Mcl1 from Beclin1 and increases the phosphorylation level of Beclin1 in U266B1 cells, thereby activating Beclin1-dependent autophagy[1].
Mcl1 Degrader-1 (5-10 μM; 16-24 h) promotes K63-linked ubiquitination of Mcl1 and its binding to p62/SQSTM1 in U266B1 cells, followed by colocalization with LC3B to achieve selective autophagic degradation[1].
Mcl1 Degrader-1 (5 μM; 24-72 h) degrades Mcl1 and triggers apoptotic cell death in U266B1 cells, and this biological process requires the participation of p62/SQSTM1, TRAF6 and UBC13. Genetic knockdown of these proteins completely abolishes the activity of this compound, which validates the above findings[1].
Mcl1 Degrader-1 (5 μM; 16–72 h) in combination with Carfilzomib (HY-10455) enhances Mcl1 degradation in U266B1 cells, a process dependent on NRF1, functional autophagy (via ATG5), and p62/SQSTM1[1].
Mcl1 Degrader-1 (500 nM-5 μM; 16-72 h) can be degraded by Carfilzomib through enhanced autophagic flux in wild-type and proteasome inhibitor-resistant multiple myeloma and NSCLC cells[1].
Mcl1 Degrader-1 (5 μM; 72 h) synergizes with Carfilzomib to reduce viability and induce apoptosis in wild-type and proteasome inhibitor-resistant multiple myeloma and non-small cell lung cancer (NSCLC) cells, and this synergy depends on p62/SQSTM1[1].
