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.
描述了用于控制与缺氧或缺血相关的脑损伤的化合物、组合物和治疗方法,通常在中风、心脏骤停或围产期窒息后发生。治疗包括给予β-苯基-α-氨基丙酸N苯胺类化合物作为拮抗剂,以抑制主要神经元兴奋性氨基酸受体位点的兴奋毒性作用。最感兴趣的化合物是具有以下结构的化合物:其中R.sup.1和R.sup.5中的每一个独立选择自氢、氟、氯、溴、甲基和乙基;其中R.sup.3选择自羟基、甲氧基、乙氧基、甲氧羰氧基、乙氧羰氧基、(2-甲基丙氧基)羰氧基和(2-丙烯氧基)羰氧基;其中R.sup.6、R.sup.7和R.sup.8中的每一个是氢;其中R.sup.9和R.sup.10中的每一个独立选择自氢、甲基和乙基;其中R.sup.11是一个或多个独立选择自氢、氟、氯、羟基、甲氧基、甲基和乙基的基团;或其互变异构体或对映体,或其药用可接受的盐或酯。
