In Vitro	BRD4 Inhibitor-18 (compound 13f) (0-10 μM; 72 hours) can suppress the proliferation of HL-60 and MV-41 cells[1]. BRD4 Inhibitor-18 (0.5 and 5 μM; 12 hours) significantly arrests MV-4-11 cells in G1 phase in a dose-dependent manner[1]. BRD4 Inhibitor-18 (0.5 and 5 μM; 12 hours) effectively induces apoptosis of MV-4-11 cells in a dose-dependent manner[1]. BRD4 Inhibitor-18 (0.5 and 5 μM; 4 hours) inhibits the expression of c-Myc protein in a dose-dependent manner[1]. Cell Proliferation Assay Cell Line: HL-60 and MV-4-11[1] Concentration: 0-10 μM Incubation Time: 72 hours Result: Suppressed the proliferation of HL-60 and MV-41 cells with IC50s of 5.52 μM and 0.42 μM. Cell Cycle Analysis Cell Line: MV-4-11 cells[1] Concentration: 0.5 and 5 μM Incubation Time: 12 hours Result: Significantly arrested MV-4-11 cells in G1 phase in a dose-dependent manner. Apoptosis Analysis Cell Line: MV-4-11 cells[1] Concentration: 0.5 and 5 μM Incubation Time: 12 hours Result: Effectively induced apoptosis of MV-4-11 cells in a dose-dependent manner. Western Blot Analysis Cell Line: MV-4-11 cells[1] Concentration: 0.5 and 5 μM Incubation Time: 4 hours Result: Inhibited the expression of c-Myc protein in a dose-dependent manner.
