CXCR4 Peptide Antagonist LY2510924

**Semantic type:** Pharmacologic Substance

**Definition:** An inhibitor of CXC chemokine receptor 4 (CXCR4), with potential antineoplastic activity. Upon subcutaneous administration, CXCR4 inhibitor LY2510924 binds to the chemokine receptor CXCR4, thereby preventing CXCR4 binding to its ligand, stromal derived factor-1 (SDF-1), and subsequent receptor activation. This may result in decreased tumor cell proliferation and migration. CXCR4, a chemokine receptor belonging to the G protein-coupled receptor (GPCR) gene family, plays an important role in chemotaxis and angiogenesis and is upregulated in several tumor cell types.
