    摘要: Compounds, compositions and methods of treatment are described to control brain damage associated with anoxia or ischemia which typically follows stroke, cardiac arrest or perinatal asphyxia. The treatment includes administration of a .beta.-phenyl-.alpha.-aminopropionic acid N phenyl amide compound 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.1 and R.sup.5 is independently selected from hydrido, fluoro, chloro, bromo, methyl and ethyl; wherein R.sup.3 is selected from hydroxy, methoxy, ethoxy, methoxycarbonyloxy, ethoxycarbonyloxy, (2-methylpropoxy)carbonyloxy and (2-propenyloxy) carbonyloxy; wherein each of R.sup.6, R.sup.7 and R.sup.8 is hydrido; wherein each of R.sup.9 and R.sup.10 is independently selected from hydrido, methyl and ethyl; wherein R.sup.11 is one or more groups independently selected from hydrido, fluoro, chloro, hydroxy, methoxy, methyl and ethyl; or a tautomer or enantiomer therefor, or a pharmaceutically-acceptable salt or ester thereof.
