Bioorg Med Chem Lett. 2006 Jan 1;16(1):200-3. doi: 10.1016/j.bmcl.2005.09.020. Epub 2005 Oct 5.

Abstract

The identification and evaluation of aryl-[1,4]diazepane ureas as functional antagonists of the chemokine receptor CXCR3 are described. Specific examples exhibit IC(50) values of approximately 60 nM in a calcium mobilization functional assay, and dose-dependently inhibit CXCR3 functional response to CXCL11 (interferon-inducible T-cell alpha chemoattractant/I-TAC) as measured by T-cell chemotaxis, with a potency of approximately 100 nM.
