Biological Activity

Description Motixafortide (BL-8040, BKT140, TF 14016, 4-fluorobenzoyl, 4F-benzoyl-TN14003, T140) is an antagonist of CXCR4 with IC50 of ～1 nM. BL-8040 induces the apoptosis of AML blasts by down-regulating ERK, BCL-2, MCL-1 and cyclin-D1 via altered miR-15a/16-1 expression.
Targets
ERK [1] Bcl-2 [1] MCL-1 [1] cyclin-D1 [1] CXCR4 [1]
(Cell-free assay)
1 nM
In vitro

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.[1]
In vivo

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.[1]

Protocol (from reference)

Cell Assay:

[1]
  • 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.
