生物活性

PROTAC BRD2/BRD4 degrader-1 (compound 15) is a potent and selective BET protein BRD4 and BRD2 degrader, connected by ligands for Cereblon and BET. PROTAC BRD2/BRD4 degrader-1 rapidly induces reversible, long-lasting, and unexpectedly selective removal of BRD4 and BRD2 over BRD3. It effectively inhibits solid tumors with low cytotoxic effect. PROTAC BRD2/BRD4 degrader-1 is composed of the BET inhibitor, a linker, and the ligand thalidomide for cereblon (CRBN)/cullin 4A[1].

(In Vitro)

PROTAC BRD2/BRD4 degrader-1 (100 nM; ≥8 hours) shows anti-proliferation activity with IC50 value of 12.25 nM, and the BRD4 protein is reduced very efficiently at treatment time of ≥8 h in MV4-11 cells[1].
PROTAC BRD2/BRD4 degrader-1 (100 nM; ≥8 hours) shows anti-proliferation activity with IC50 value of 12.25 nM, and the BRD4 protein is reduced very efficiently at treatment time of ≥8 h in MV4-11 cells[1].
PROTAC BRD2/BRD4 degrader-1 (1 nM, 3 nM, 0.1 μM, 0.3 μM; 24-48 hours) induces MV4-11 apoptosis lines[1].
PROTAC BRD2/BRD4 degrader-1 exhibits excellent anti-proliferative activity in 6 leukemia cell lines of NCI. Among them, the GI50 values of the three leukemia cell lines were lower than 50 nM, consistent with the activity of leukemia MV4-11 cells[1].
PROTAC BRD2/BRD4 degrader-1 has good anti-proliferation activity including prostate Cancer (22RV1 IC50: 0.081 μM), colon cancer (colo-205 IC50: 0.1557 μM) and thyroid cancer(TT IC50: 0.037451 μM)[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
