Synthesis and biological evaluation of the novel histamine H-3 receptor ligands is described. Two series of ethers (aliphatic and aromatic) have been prepared by four different methods. Compounds were evaluated for their affinities at recombinant human H-3 receptor stably expressed in CHO cells. The ethers show from low to moderate in vitro affiities in nanomolar concentration range. The most potent compound was the 1-[3-(4-tert-butylphenoxy)propyl]-4-piperidino-piperidine 16 (hH(3)R K-i = 100 nM). Several members of the new series investigated under in vivo conditions, proved to be inactive. (C) 2008 Published by Elsevier Ltd.
