The structure-human CXCR3 binding affinity relationship of a series of pyridyl-piperazinyl-piperidine derivatives was explored. The optimization campaign highlighted the pronounced effect of 2'-piperazine substitution on CXCR3 receptor affinity. Analog 18j, harboring a 2'(S)-ethylpiperazine moiety, exhibited a human CXCR3 IC(50) of 0.2 nM. (C) 2011 Elsevier Ltd. All rights reserved.
