Glutamic acid analogs containing 3- and 4-methyl and 2-, 3-, and 4-phenyl substituents were prepared. The 3- and 4-methyl- and 3- and 4-phenylglutamic acids did not inhibit Plasmodium berghei and were nontoxic to the host (mice) at 640 mg/kg. The five analogs in addition to 2-methlglutamic acid were inactive against Lactobacillus casei at 1000 mug/ml in a defined medium: against Escherichia coli, only
制备了含有3-和4-甲基以及2-,3-和4-苯基取代基的谷氨酸类似物。3-和4-甲基-和3-和4-苯基谷氨酸不抑制伯氏疟原虫并且以640 mg / kg的剂量对宿主(小鼠)无毒。除2-甲基谷氨酸外,这五种类似物在规定的培养基中以1000杯/毫升的速率对干酪乳杆菌无活性:对于大肠杆菌,只有2-甲基谷氨酸在10,000杯/毫升的情况下产生27%的抑制作用。在低于10,000杯/毫升的特定培养基中,所有六个类似物均未能抑制黑曲霉,米曲霉,木霉菌和绿霉菌。
