• 产品描述： Motixafortide (BL-8040, BKT140, TF 14016, 4-fluorobenzoyl, 4F-benzoyl-TN14003, T140) 是一种 CXCR4 的拮抗剂，IC50值约为1 nM。BL-8040 通过改变的miR-15a/16-1的表达，下调 ERK、BCL-2、MCL-1 和 cyclin-D1，诱导AML胚的凋亡

• 靶点： ERK; Bcl-2; MCL-1; cyclin-D1; CXCR4(Cell-free assay):1 nM;CXCR

• 体外研究：
  Treatment with BL-8040 induces the robust mobilization of AML blasts from the BM. In addition, AML cells exposed to BL-8040 undergoes differentiation. BL-8040 induces the apoptosis of AML cells in vitro. This apoptosis is mediated by the up-regulation of miR-15a/miR-16-1, resulting in down-regulation of the target genes BCL-2, MCL-1 and cyclin-D1. Overexpression of miR-15a/miR-16-1 directly induces leukemic cell death. BL-8040-induced apoptosis is also mediated by the inhibition of survival signals via the AKT/ERK pathways

• 体内研究：
  BL-8040 induces the apoptosis of AML cells in vivo. Treatment with a BCL-2 inhibitor induces apoptosis and acts together with BL-8040 to enhance cell death. BL-8040 also synergizes with FLT3 inhibitors to induce AML cell death. Importantly, this combined treatment prolongs the survival of tumor-bearing mice and reduces minimal residual disease in vivo

• 细胞实验： Cell lines: The leukemic cell lines (MV4-11, THP-1, U937, HL-60) Concentrations: 0.1 μM, 1 μM, 10 μM, 20 μM Incubation Time: 24 h, 48 h Method: Cells are seeded in triplicate at 2×105 cells/well in a total volume of 250 μl in a 96-well plate in medium supplemented with 1% FCS RPMI medium for 24hr in the presence of BL-8040/AMD3100 (0.1, 1, 10 or 20μM) or ABT-199 (0.01, 0.1, 1 or 10μM). To test the combination of BL-8040 and ABT-199, cells are incubated for 24hr with BL-8040 (20μM) and ABT-199 (0.01, 0.1, 1 or 10μM). To test the combined effects of BL-8040 and AC220, cells are incubated for 48 hr with BL-8040 (20μM), AC220 (50nM) or a combination of the two. After incubation, cells are stained with propidium iodide (PI), and the percentage of dead cells (PI+ cells) in the culture is measured using a FACSCalibur machine

• 动物实验： Animal Models: female NOD scid gamma (NSG) mice (7-9 weeks old) Dosages: 400 μg/mouse Administration: SC
