This invention provides heterocyclic compounds of formula (I) that are potentially useful in the treatment of neuropsychiatric disorders associated with progressive processes leading to neuronal necrosis and dysfunction. In particular, the novel compounds which do not bind to muscarinic receptors are inhibitors of delayed neuronal death as shown in the gerbil bilateral occlusion model of ischemia.
