PROTAC CDK9 degrader-13
PROTAC CDK9 degrader-13 is a selective CDK9 degrader acting via the ubiquitin-proteasome system. PROTAC CDK9 degrader-13 induces apoptosis in acute myeloid leukemia cells. PROTAC CDK9 degrader-13 suppresses tumor growth in vivo and has a defined safety profile. PROTAC CDK9 degrader-13 can be used for the research of acute myeloid leukemia.

PROTAC CDK9 degrader-13 (compound D6) (72 h) potently inhibits the proliferation of MV-4-11, MOLM-13, HL-60, THP-1 and HCT116 cells, with the strongest activity against MOLM-13 cells (IC50 = 1.88 μM), and shows no obvious cytotoxicity against MCF-7 and 293T cells[1].
PROTAC CDK9 degrader-13 (1-24 μM; 24 h, 4 μM; 12-48 h) induces time- and concentration-dependent degradation of CDK9 in MOLM-13 cells[1].
PROTAC CDK9 degrader-13 (4 μM; 24-36 h) selectively induces CDK9 degradation in MOLM-13 cells, without causing significant degradation of CDK2, CDK4 or CDK8[1].
PROTAC CDK9 degrader-13 (4-8 μM) induces proteasome-dependent, CRBN ligand-competitive degradation of CDK9 in MOLM-13 cells[1].
PROTAC CDK9 degrader-13 (2-8 μM; 36 h) dose-dependently inhibits the migration of MOLM-13 cells[1].
PROTAC CDK9 degrader-13 (1-4 μM; 36 h) induces apoptosis in MOLM-13 cells[1].
