International Classification:

A61K 314965

US Classification:

514300, 51425502, 544405, 546113

Abstract:

Disclosed are 1H-Pyrrolo[3,2-b]pyridine-3-carboxylic acid amides that bind to the benzodiazepine site of GABA receptors. Such compounds can be used to modulate ligand binding to GABA receptors in vivo and in vitro, and are particularly useful in the treatment of a variety of central nervous system (CNS) disorders in humans, domesticated companion animals, and livestock animals.

Abstract:

This invention relates to benzimidazoles, pyridylimidazoles and related bicyclic heteroaryl compounds, all of which may be described by of Formula I The invention is particularly related to such compounds that bind with high selectivity and high affinity to the benzodiazepine site of GABAreceptors. This invention also relates to pharmaceutical compositions comprising such compounds and to the use of such compounds in treatment of certain central nervous system (CNS) diseases. Novel processes for preparing compounds of Formula I are disclosed. This invention also relates to the use of benzimidazoles, pyridylimidazoles and related bicyclic heteroaryl compounds of Formula I in combination with one or more other CNS agents to potentiate the effects of the other CNS agents. Additionally this invention relates to the use such compounds as probes for the localization of GABAreceptors in tissue sections.
