2-�(1H-benzimidazol-2-ylsulfinyl)methyl!benzenamines

A class of imidazo�1,2-a!pyridinylalkyl compounds is described for treatment to reduce neurotoxic injury associated with anoxia or ischemia which typically follows stroke, cardiac arrest or perinatal asphyxia. The treatment includes administration of a compound of this class alone or in a composition in an amount effective as an antagonist to inhibit excitotoxic actions at major neuronal excitatory amino acid receptor sites. Compounds of most interest are those of the formula: ##STR1## wherein each of R.sup.22, R.sup.23 and R.sup.24 is independently selected from hydrido, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl; wherein each of Y.sub.m and Y.sub.n is a spacer group independently selected methylene and ethylene radicals which may be unsubstituted and from methylene radicals which may be substituted with a group selected from halo, hydroxy and oxo; wherein each of m and n is a number independently selected from zero to two, inclusive; wherein each X and T is one or more groups independently selected from hydrido, alkyl, cycloalkyl, halo, haloalkyl, hydroxy, hydroxyalkyl, alkoxy, alkoxyalkyl and alkanoyl; or a pharmaceutically-acceptable salt thereof.
