Uses
N-[(1R)-1-[3-(4-Ethoxyphenyl)-3,4-dihydro-4-oxopyrido[2,3-d]pyrimidin-2-yl]ethyl]-N-(3-pyridinylmethyl)-4-(trifluoromethoxy)benzeneacetamide is a selective and potent antagonist of the chemokine receptor CXCR3.
Biological Activity
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) th at 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.).
