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

Solid

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.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

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.
