its total synthesis starting from (S)-dimethylmalate, whereas that of 5 was determined by conversion into the known compound methyl (S)-4-[(S)-1-(1-naphthalen-1-yl)ethylcarbamoyl]-3-hydroxy-3-methylbutanoate (14). Compounds 3 and 5 exhibited an inhibitory effect on cell growth of the androgen-insensitive DU-145 prostate cancer cells, which suggests that these fungal polyamine conjugates, like other
两种衍生自肉桂酸的新酰胺,即 (R)-2-羟基腐胺二肉桂酰胺 (4) 和绿叶酸(2R)-2-[(S)-3-羟基-3-甲基戊二酰氧基]腐胺二肉桂酰胺} (5) , 除了已知的化合物美替宁 (N1,N8-二肉桂酰亚精胺) (3) 从担子菌 Pholiota spumosa 的子实体中分离出来。4 的绝对构型通过从 (S)-苹果酸二甲酯开始全合成确定为 (R),而 5 的绝对构型通过转化为已知化合物甲基 (S)-4-[(S)-1-( 1-萘-1-基)乙基氨基甲酰基]-3-羟基-3-甲基丁酸酯(14)。化合物 3 和 5 对雄激素不敏感的 DU-145 前列腺癌细胞的细胞生长表现出抑制作用,这表明这些真菌多胺缀合物与其他多胺类似物一样,可能具有对抗雄激素非依赖性前列腺癌的化学治疗潜力。(© Wiley-VCH Verlag GmbH & Co.
