A class of diacid-containing benzimidazole 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 Y.sub.m is --CH.sub.2 -- or --CH.sub.2 --CH.sub.2 --; wherein m is one; wherein X is one or more groups attachable at one or more of the 4-, 5-, 6- and 7-ring positions not occupied by the phosphonoalkyl moiety; wherein each X is independently selected from hydrido, halo, alkyl, cycloalkyl, cycloalkylalkyl, haloalkyl, alkenyl, alkynyl, phenyl, benzyl, hydroxy, hydroxyalkyl, alkoxy, phenoxy, alkoxyalkyl, benzyloxy, cyano, alkanoyl, alkylthio, arylthio and amino; wherein each of R.sup.10, R.sup.13 and R.sup.14 is independently selected from hydrido, alkyl, benzyl and phenyl; and wherein V is selected from hydrido and acyl; or a pharmaceutically-acceptable salt thereof.
本文描述了一类含有二酸基苯并咪唑化合物,用于治疗与缺氧或缺血相关的神经毒性损伤,通常是中风、心脏骤停或围产期窒息后的。该治疗包括单独或在组合物中给予该类化合物,以有效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公式中的化合物:其中Ym为--CH2--或--CH2--CH2--;其中m为1;其中X是可连接到4、5、6和7环位置中未被磷酸烷基占据的一个或多个基团;其中每个X独立地选自氢基、卤素、烷基、环烷基、环烷基烷基、卤素烷基、烯基、炔基、苯基、苄基、羟基、羟基烷基、烷氧基、苯氧基、烷氧基烷基、苄氧基、氰基、烷酰基、烷基硫基、芳基硫基和氨基;其中每个R10、R13和R14独立地选自氢基、烷基、苄基和苯基;其中V选自氢基和酰基;或其药学上可接受的盐。
