3、BIOLOGICAL ACTIVITY物活性 FL-411種有效的選擇性 BRD4 抑制劑，抑制 BRD4(1)，IC50 為 0.430.09 M。IC50 & Target BRD4(1)0.43 M (IC50)體外研究 FL-411 is a selective BRD4 inhibitor. Binding affinities of FL-411 are measured by TR-FRET against the firstand second bromodomains of BRD2(1), BRD4(1), and BRD4(2) with IC50s of 24.600.

4、70 M, 0.470.02 M,0.930.05 M, respectively. FL-411 possesses a good BRD4(1) inhibition activity (IC50=0.430.09 M),antiproliferative activity (MCF-7, IC50=1.620.06 M; MDA-MB-231, IC50=3.270.14 M), and autophagicactivity (42.29% in MCF-7 cells), as well as displays a low toxicity against MCF10A cells).

5、 FL-411 inducesATG5-dependent autophagy-associated cell death (ACD) by blocking BRD4-AMPK interaction and thusactivating AMPK-mTOR-ULK1-modulated autophagic pathway in breast cancer cells 1.體內(nèi)研究 To evaluate the antitumor activity of FL-411 in vivo, two breast tumor xenograft models, namely, MCF-7 an

6、dMDA-MB-231 cell lines models, are used. The in vivo study is conducted using three different doses of FL-411: 25 mg/kg, 50 mg/kg, and 100 mg/kg. In all the models, FL-411 shows significant tumor growth inhibitionin a dose-dependent manner as determined by 80% and 76% tumor growth inhibition ratio i

7、n MCF-7 andMDA-MB-231 cell models, respectively. A remarkable loss of tumor weights is observed in all dose groups (p1.PROTOCOLCell Assay 1 The MCF-7 and MDA-MB-231 cells are dispensed in 96-well flat bottom microtiter plates at a density of5104 cells/mL. After 24 h incubation, MCF-7 or MDA-MB-231 c

8、ells are treated with 1.5 and 3 M FL-411,respectively. 3-MA (1 mM) is added 1 h before treated with FL-411. After treatment, cell viability is measuredby the MTT assay. 5 mg/mL MTT is added to each well. After 4 h incubation, the medium is removed and150 L of DMSO is added to each well to dissolve t

10、neously with MCF-7 cells or MDA-MB-231 cells (5106 cells/mouse), respectively. When the tumors reach 100 mm3 in volume, the mice aredivided into four groups for each cell line. Three groups are treated with different doses of FL-411 (low dose,25 mg/kg; median dose, 50 mg/kg; high dose, 100 mg/kg) on

During the treatment, the tumor volumesand body weight are measured every 3 days until the end of the study. At the end of treatment, all mice aresacrificed. The tumor tissues are har
