Three new amino acid derivatives, oxalamido-L-phenylalanine methyl ester (1), oxalamido-L-leucine methyl ester (2), and lumichrome hydrolyzate (3), together with nine known compounds (4–12), were isolated from the solid culture of edible mushroom Pleurotus ostreatus. Their structures were elucidated on the basis of extensive spectroscopic analysis. The absolute configurations of 1 and 2 were established
从中分离出三种新的氨基酸衍生物,草酰氨基-L-苯丙氨酸甲酯(1),草酰氨基-L-亮氨酸甲酯(2)和发光色素水解物(3),以及九种已知化合物(4-12)。食用菌平菇的固体培养。在广泛的光谱分析的基础上阐明了它们的结构。1和2的绝对配置通过手性合成建立并通过其总合成产物和天然分离物的圆二色性(CD)分析确认。对所有新化合物的抗氧化作用,抗微生物活性和细胞毒性活性进行了评估。化合物1-3对白色念珠菌的抗真菌活性较弱,最小抑菌浓度(MIC)值为500μg/ ml。
