In Vitro LY2510924 specifically blocks SDF-1 binding to CXCR4 with IC50 value of 0.079 nM, and inhibits SDF-1–induced GTP binding with Kb value of 0.38 nM. In human lymphoma U937 cells expressing endogenous CXCR4, LY2510924 inhibits SDF-1–induced cell migration with IC50 value of 0.26 nM and inhibits SDF-1/CXCR4-mediated intracellular signaling. LY2510924 exhibits a concentration-dependent inhibition of SDF-1–stimulated phospho-ERK and phospho-Akt in tumor cells. Biochemical and cellular analyses reveals that LY2510924 has no apparent agonist activity[1]. LY2510924 chiefly inhibits the proliferation of AML cells with little induction of cell death and reduces protection against chemotherapy by stromal cells[2].

Animal Admin Mice: SCID female mice are injected intravenously with MDA-MB-231 cells, and are treated subcutaneously with vehicle (1×PBS) or 3 mg/kg of LY2510924 formulated in 1×PBS. Group 1 and 2 animals receive vehicle or 3 mg/kg of LY2510924 twice daily for days with treatment beginning on one day before tumor cell injection. Group 3 animals receive 3 mg/kg of LY2510924 15 twice daily for 13 days with treatment beginning one day after tumor cell injection. After treatment, lung tissues are fixed in 10% neutral-buffered formalin for at least 24 hours and lung lobes are present in histologic sections[1].
