Dual serotonin transporter inhibitor/histamine H3 antagonists: Development of rigidified H3 pharmacophores

A series of tetrahydroisoquinolines acting as dual serotonin transporter inhibitor/histamine H3 antagonists is described. The introduction of polar aromatic spacers as part of the histamine H3 pharmacophore was explored. A convergent synthesis of the final products allowing late stage introduction of the aromatic side chain was developed. In vitro and in vivo data are discussed.
