AMG 487 is an orally available, potent and selective chemokine (C-X-C motif) receptor 3 (CXCR3) antagonist (IC50 = 8/8.2 nM against CXCL10/11 (IP-10/ITAC) for CXCR3 binding) that inhibits CXCR3 ligands-induced cell migration (CXCL10/11/9 IC50 = 8/15/36 nM). AMG 487 inhibits ITAC-induced calcium mobilization in vitro (IC50 = 5 nM) and reduces bleomycin-induced cellular lung recruitment in wild-type mice to the same level as in Cxcr3-deficient mice in vivo (3 mg/kg b.i.d. s.c.).
Mantle cell lymphoma (MCL) is a unique subtype of B-cell non-Hodgkin lymphoma with a generally aggressive and heterogeneous clinical course. Chemokines are one of the complex components in the tumor microenvironment (TME), and they play a vital role in tumor
A series of quinazolinone-derived inhibitors of the CXCR3 receptor have been synthesized and their affinity for the receptor evaluated. Compounds were evaluated in a (125)I-IP10 displacement assay and in in vitro cell migration assays to IP10, ITAC, and MIG using
CXCL9 secreted by tumor-associated dendritic cells up-regulates PD-L1 expression in bladder cancer cells by activating the CXCR3 signaling
Tumor cells aberrantly express chemokines and/or chemokine receptors, and some may promote tumor growth and metastasis. We examined the expression and function of chemokine receptor CXCR3 in a syngeneic murine model of metastatic breast cancer. By flow cytometry, CXCR3 was
