描述 | QCA570 is a potent PROTAC targeting on BET, consist of an optimized BET ligand QCA276 linked to a CRBN E3 ligand. Treatment with QCA570 led to a dose-dependent depletion of BRD2, 3 and 4 at concentration ranging in 0.01-10nM in MV4;11 and RS4;11 cell lines post 24h, accompanied with downregulation of c-MYC and induction of apoptosis shown by cleaved PARP and Caspase-3. QCA570 exhibited potent anti-proliferation against acute leukemia cell lines with IC50 values of 8.3, 62 and 32pM,for MV4;11, MOLM13, and RS4;11 cell line, respectively, post 96-hour treatment. A good pharmacokinetic and pharmacodynamics properties of QCA570 was shown as a single intravenous dose of 1 or 5mg/kg QCA570 post 24h achieved downregulation of BRD2, 3, 4, c-MYC and increased cleaved PARP in tumors of SCID mice bearing RS4;11. Suppression of tumor growth could be observed in both RS4;11 and MV4;11 xenograft models in mice dosed of QCA570 at 1 or 5 mg/kg, i.v., three times a week for 2 weeks[1]. |
