描述 | Through binding with CC- and CXC-chemokines, CCR and CXCR, the subsets of the chemokine receptor family can trigger an intracellular signal transduction cascade, thus mediating the recruitment of immune cells to the inflammation or infection sites and implicated in several immuno-related disease states, organogenesis, angiogenesis and tumor growth and metastasis. LY2510924 is a potent and selective CXCR4 inhibitor with IC50 value of 0.079nM for blocking SDF-1α binding to CXCR4. LY2510924 could completely inhibit SDF-1-mediated GTP binding with Kb value of 0.38nM. Selective inhibition by LY2510924 of SDF-1-induced migration of U937 cells can be achieved in a concentration-dependent manner with IC50 of 0.26nM. As prediction, the SDF-1- and CXCR4-mediated cell signaling, including p-ERK and p-AKT, can be inhibited by LY2510924 at concentration of 3.3nM and 0.33nM in HeLa cells, as well as IC50 values of 1.4 and 1.2nM, respectively, in Namalwa cells expressing high level of CXCR4. Subcutaneous injection with 3mg/kg LY2510924, BID, for 7 days, significantly inhibit the tumor growth of an NHL Namalwa xenograft model. Antitumor growth activities of LY2510924 can be also observed at dose of 2mg/kg or 5mg/kg in solid cancer xenograft models, RCC A-498 and A549 xenografts. Subcutaneous injection with 3mg/kg LY2510924 twice daily for 13 or 15 days inhibited breast cancer metastasis in the MDA-MB-231 model due to blocking migration/homing process of tumor cells to reduce the colony numbers of lung metastasis, as well as inhibiting cell proliferation to reduce the size of the colonies after tumor cell homing to the lung[1]. | ||
作用机制 | LY2510924 can occupy the binding pocket and possess ligand-receptor interactions with CXCR4 residues.[1] |
