生物活性

製品説明 LY2510924 is a potent and selective CXCR4 antagonist that specifically blocks SDF-1 binding to CXCR4 with IC50 value of 0.079 nmol/L and inhibits SDF-1-induced GTP binding with Kb value of 0.38 nmol/L.
in vitro In human lymphoma U937 cells expressing endogenous CXCR4, LY2510924 inhibits SDF-1-induced cell migration with IC50 value of 0.26 nmol/L 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 reveal that LY2510924 has no apparent agonist activity. LY2510924 has no inhibitory activities against other chemokine receptors including CCR1, CCR2, CXCR2, and CXCR3 at the concentrations tested. Similarly, there is no activity observed among serotonin, dopamine, and opioid receptors[1].
in vivo LY2510924 has acceptable in vivo stability and a pharmacokinetic profile similar to a typical small-molecular inhibitor in preclinical species. LY2510924 shows dose-dependent inhibition of tumor growth in human xenograft models developed with non-Hodgkin lymphoma, renal cell carcinoma, lung, and colon cancer cells that express functional CXCR4. In MDA-MB-231, a breast cancer metastatic model, LY2510924 inhibits tumor metastasis by blocking migration/homing process of tumor cells to the lung and by inhibiting cell proliferation after tumor cell homing. LY2510924 has a dramatically improved in vivo stability with a half-life of 3 to 5 hours in preclinical species and 9.16 hours in humans at the recommended phase II dose[1].

実験の流れ

U937 cells are harvested and washed once with chemotaxis assay buffer prepared with 1× RPMI medium containing 10 mmol/L HEPES, pH 7.5, and 0.3% BSA. Cells are then resuspended in assay buffer at a density of 5 × 106 cells/mL. The assay is performed in a 96-well ChemoTx plate. Generally, 50 μL of cell mixture with or without LY2510924 was plated on the upper chamber, and 30 μL of SDF-1α (10 ng/mL) prepared in 1× chemotaxis buffer was added to the lower chamber. The plate is then incubated for 2.5 hours at 37°C. Following the incubation, 5 μL of CellTiter 96 AQ is added into the lower chamber. The plate is then incubated for 60 minutes at 37°C. The migrated cells are detected by measuring the absorbance at 492 nm.
