  CXCR3 antagonists: Quaternary ammonium salts equipped with biphenyl- and polycycloaliphatic-anchors

  摘要：

  Small-molecule ligands for the CXCR3 chemokine receptor receive considerable attention as a means to interrogate the roles of CXCR3 in vitro and in vivo and/or to potentially treat various conditions such as inflammatory diseases and cancer. We have synthesized and explored a novel class of small-molecule antagonists for CXCR3. A medium-throughput screen revealed an adamantane-guanidine as a hit. The guanidine unit was replaced by a small quaternary ammonium group, leading to ca. 5-fold increase in affinity. Substitution of the adamantane group by a myrtenyl moiety further increased affinity, while the benzyl group was decorated with an additional (substituted) aryl ring. This led to the identification of several bisaryl-based ligands with CXCR3 affinities of around 100 nM and with the ability to antagonize the functional activity of CXCL10. (C) 2011 Elsevier Ltd.

  small‐molecule ligands with photoswitchable efficacy in which both configurations bind the target protein but exert distinct pharmacological effects, that is, stimulate or antagonize GPCR activation. Our design was based on a previously identified efficacy hotspot for the peptidergic chemokine receptor CXCR3 and resulted in the synthesis and characterization of five new azobenzene‐containing CXCR3 ligands.

  The G protein-coupled chemokine receptor CXCR3 plays a role in numerous inflammatory events. The endogenous ligands for the chemokine receptors are peptides, but in this study we disclose small-molecule ligands that are able to activate CXCR3. A class of biaryl-type compounds that is assembled by convenient synthetic routes is described as a new class of CXCR3 agonists. Intriguingly, structure-activity relationship and structure-function relationship studies reveal that subtle chemical modifications on the outer aryl ring (e.g., either the size or position of a halogen atom) result in a full spectrum of agonist efficacies on CXCR3. Quantum mechanics calculations and nuclear Overhauser effect spectroscopy NMR studies suggest that the biaryl dihedral angle and the electronic nature of ortho-substituents play an important role in determining agonist efficacies. Compounds 38 (VUF11222) and 39 (VUF11418) are the first reported nonpeptidomimetic agonists on CXCR3, rendering them highly useful chemical tools for detailed assessment of CXCR3 activation as well as for studying downstream CXCR3 signaling.
