Use of bridged tricyclic amine derivatives as anti-ischemic agents

Abstract

Certain bridged tricyclic amine compounds are described as being therapeutically effective in treatments of CNS disorders resulting from neurotoxic damage or neurodegenerative diseases, particularly those CNS disorders resulting from ischemic events. Compounds of particular interest for use as neuroprotective agents are those of the formula ##STR1## wherein each of R.sup.1 and R.sup.2 is independently selected from hydrido, loweralkyl, benzyl and phenyl; wherein each of R.sup.1 through R.sup.7 is independently selected from hydrido, loweralkyl, hydroxy, benzyl, phenyl, loweralkoxy, phenoxy, benzyloxy, halo and haloloweralkyl; wherein R.sup.18 may be selected from hydrido, loweralkyl, cycloalkyl of five or six carbon atoms, cycloalkylalkyl of six or seven carbon atoms, phenyl, hydroxyloweralkyl, and heteroaryl selected from saturated or fully unsaturated heterocyclic rings containing five to seven ring members of which one or two ring members are nitrogen atom; wherein each X is independently one or more groups selected from hydrido, hydroxy, loweralkyl, benzyl, phenyl, loweralkoxy, phenoxy, haloloweralkyl, halo, and lower-alkanoyl; and wherein each of R.sup.23 through R.sup.30 is independently selected from hydrido, lower alkyl, benzyl, phenyl and halo; wherein R.sup.18 together with one of R.sup.23, R.sup.24, R.sup.29 or R.sup.30 may form a fused heterocyclic ring containing five or six ring members; or a pharmaceutically-acceptable salt thereof.
