Acetic acid derivatives of the formula: ##STR1## and pharmaceutically acceptable alkali metal salts thereof, wherein R represents the radical ##STR2## in which R.sub.1 and R.sub.2, which may be the same or different, each represent an alkyl radical having from 1 to 4 carbon atoms, R.sub.3 represents a hydrogen atom or a methyl radical and n is an integer in the range of from 0 to 3 inclusive. They possess a competitive inhibitory activity with respect to .gamma.-aminobutyric .alpha.-ketoglutaric transaminase as well as antianoxic and anticonvulsant properties and they are useful for treating central neurological disorders whether resulting or not from cerebral ischemia.
乙酸衍生物的化学式为:##STR1##及其在药学上可接受的碱金属盐,其中R代表基团##STR2##其中R.sub.1和R.sub.2,可以相同也可以不同,每个代表具有1至4个碳原子的烷基基团,R.sub.3代表氢原子或甲基基团,n是在0至3范围内的整数。它们具有相对于γ-氨基丁酸α-酮戊二酸转氨酶的竞争性抑制活性,以及抗缺氧和抗抽搐特性,可用于治疗中枢神经系统疾病,无论是由脑缺血引起还是其他原因。
