Non-imidazole alkylamines as histamine H3-receptor ligands and their therapeutic applications

摘要

Use of a compound of formula (A), wherein: W is a residue which imparts antagonistic and/or agonistic activity at histamine H₃-receptors when attached to an imidazole ring in 4(5) position; R¹ and R² may be identical or different and represent each independently a lower alkyl or cycloalkyl, or taken together with the nitrogen atom to which they are attached, a saturated nitrogen-containing ring (i) as defined, a non-aromatic unsaturated nitrogen-containing ring (ii) as defined, a morpholino group, or a N-substituted piperazino group as defined for preparing medicaments acting as antagonists and/or agonists at the H₃-receptors of histamine.
