Imidazole compounds substituted with a six or seven membered heterocyclic ring containing two nitrogen atoms

Abstract

This invention discloses novel imidazoles substituted with a six or seven membered heterocyclic ring which contains two nitrogen atoms as part of the heterocyclic ring structure. These compounds have excellent histamine-H3 receptor antagonist activity. Also disclosed are methods for preparing such compounds. In another embodiment, the invention discloses pharmaceutical compositions comprising such imidazoles as well as methods of using them to treat allergy (for example asthma), inflammation, hypertension, raised intraocular pressure (such as glaucoma)—i.e., a method of lowering intraocular pressure, sleeping disorders, states of hyper and hypomotility and acidic secretion of the gastrointestinal tract, hypo and hyperactivity of the central nervous system (for example, agitation and depression) and other CNS disorders (such as Alzheimer's Disease, schizophrenia, and migraine). An illustrative inventive imidazole is shown below:
