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的苯并咪唑化合物,用于治疗与缺氧或缺血相关的神经毒性损伤,通常在中风、心脏骤停或围产窒息后发生。治疗包括单独或在组合物中以有效量的拮抗剂形式给予该类化合物,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公式中的化合物:##STR1## 其中Ym为--CH2--或--CH2--CH2--;其中m为1;其中X为一个或多个可连接到4-、5-、6-和7-环位置上未被磷酸烷基部分占据的基团;其中每个X独立地从氢基,卤素,烷基,环烷基,环烷基烷基,卤代烷基,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,酰基,烷硫基,芳基硫基和氨基中选择;其中R10,R13和R14中的每一个独立地选择自氢基,烷基,苄基和苯基;V选择自氢基和酰基;或其药学上可接受的盐。
