A new family of H3 receptor antagonists based on the natural product Conessine

Bioorg Med Chem Lett. 2008 Feb 15;18(4):1490-4. doi: 10.1016/j.bmcl.2007.12.059. Epub 2007 Dec 25.

Abstract

A new family of Histamine H(3) receptor antagonists (5a-t) has been prepared based on the structure of the natural product Conessine, a known H(3) antagonist. Several members of the new series are highly potent and selective binders of rat and human H(3) receptors and display inverse agonism at the human H(3) receptor. Compound 5n exhibited promising rat pharmacokinetic properties and demonstrated functional antagonism of the H(3) receptor in an in-vivo pharmacological model.
