Bioorg Med Chem Lett. 2010 Sep 1;20(17):5004-8. doi: 10.1016/j.bmcl.2010.07.052. Epub 2010 Jul 16.

Abstract

A structure-activity relationship study of the lead piperazinylcarbonylpiperidine compound 3 resulted in the identification of 4-benzimidazolyl-piperidinylcarbonyl-piperidine 6h as a histamine-3 (H(3)) receptor antagonist. Additional optimization of 6h led to the identification of compounds 11i-k with K(i) <or= 0.5 nM and good in vivo activity.
