PROTAC BET Degrader-15 is a BET PROTAC degrader with DC50 values of BRD2, BRD3, and BRD4, respectively. PROTAC BET Degrader-15 induces significant G2/M phase cell cycle arrest and triggers apoptosis. PROTAC BET Degrader-15 causes marked downregulation of c-Myc, accompanied by upregulation of the cell cycle inhibitory protein p21, downregulation of CDK6, and an increase in the apoptosis marker cleaved PARP. PROTAC BET Degrader-15 is applicable to the research of hematologic malignancies and lung cancer[1].
