体外研究 (In Vitro) | BRD4/CK2-IN-1 (compound 44e) (0-25 μM; 24 hours) has anti-proliferation effect withIC50s of 2.66 and 3.52 μM in MDA-MB-231 and MDA-MB-468 cells, respectively[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) dose-dependently induces apoptosis of MDA-MB-231 and MDA-MB-468 cells[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) dose-dependently downregulates Bcl-2 but upregulates Bax and cleaved caspase-3[1]. BRD4/CK2-IN-1 (0-10 μM; 24 hours) significantly downregulates the autophagy substrate p62 and up-regulated beclin-1 and LC3II in MDA-MB-231 and MDA-MB[1].
