Description

Motixafortide (BKT140 4-fluorobenzoyl) is a novel CXCR4 antagonist with an IC50 vakue of ～1 nM.

IC50 & Target[1]

CXCR4

~1 nM (IC50)

In Vitro

Motixafortide (BKT140) displays selective toxicity toward AmL and MM cells. Treatment with Motixafortide (BKT140) can overcome IL-6 dependent proliferation and survival of ARH77 MM cells. Motixafortide (BKT140) specifically triggers CXCR4-dependent cell death in leukemia and MM cells. Motixafortide (BKT140) stimulates apoptotic cell death in leukemia and MM cells[2].

In Vivo

Subcutaneous injections of Motixafortide (BKT140) significantly reduces, in a dose-dependent manner, the growth of human acute myeloid leukemia and multiple myeloma xenografts. Tumors from animals treated with Motixafortide (BKT140) are smaller in size and weights, had larger necrotic areas and high apoptotic scores[2].

Cell Assay
[2]

Hematopoietic cancer cells are incubated with different concentrations of Motixafortide (BKT140) or AMD3100 for 24 hours. Motixafortide (BKT140) is treated with 1M hydrochloric acid (HCL) to achieve a pH of 2.7 to 3 at room temperature for 30 minutes and the pH is adjusted to 7 using concentrated NaOH. Proteinase K is added to Motixafortide (BKT140) at a final concentration of 100 mg/mL, incubated at 37°C for 1 hour, and inactivated by heat treatment (65°C for 30 minutes). After incubation, cells are stained with propidium iodide and the percent of viable PI-negative cells in culture is determined[2].

Animal Administration
[2]

Mice: Severe combined immune-deficient (SCID)/beige mice (C.B-17/IcrHsd-SCID-bg) are used in the study. NB4 cells resuspended in PBS are injected subcutaneously into the flanks of the mice (200 μL per mouse containing 5×106 cells). Tumor growth is monitored daily, and mice are randomized to drug-treated or control PBS-treated groups (10 mice per group) when the tumor size (width×length) reaches 0.04 cm2. BKT140 is administered subcutaneously at a dose of 200 μg per mouse each day for 5 days[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
