Biological Activity

Motixafortide (BL-8040) is an antagonist of CXCR4 with IC50 value of 1 nM. Motixafortide (BL-8040) specifically triggers CXCR4-dependent cell death in leukemia and MM cells and it stimulates apoptotic cell death in leukemia and MM cells. Treatment with Motixafortide (BL-8040) can overcome IL-6 dependent proliferation and survival of ARH77 MM cells. 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.

Cell Experiment
Cell lines The leukemic cell lines (MV4-11, THP-1, U937, HL-60)
Preparation 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.
Concentrations 0.1 μM, 1 μM, 10 μM, 20 μM
Incubation time 24 h, 48 h
Animal Experiment
Animal models female NOD scid gamma (NSG) mice (7-9 weeks old)
Formulation -
Dosages 400 μg/mouse
Administration s.c.
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
