The present patent application concerns compounds of formula (I) with R1 and R2 taken together with the nitrogen atom to which they are attached, form a mono or bicyclic saturated nitrogen-containing ring; their preparation and their use as a H3 receptor ligand for treating e.g. CNS disorders like Alzheimer's disease.
Pre-clinical investigation of some aryl-piperidinyl ether histamine H3 receptor antagonists revealed a strong hERG binding. To overcome this issue, we have developed a QSAR model specially dedicated to H3 receptor ligands. This model was designed to be directly applicable in medicinal chemistry with no need of molecular modeling. The resulting recursive partitioning trees are robust (80-85% accuracy), but also simple and comprehensible. A novel promising lead emerged from our work and the structure-activity relationships are presented. (C) 2011 Elsevier Ltd. All rights reserved.
