The structures of cirratiomycin A and B have been elucidated by a degradative study and 1H-and 13C-NMR spectral analysis. It is revealed here that cirratiomycin A and B are heptapeptides containing three unusual new amino acids, viz, hydroxymethylserine, 2,3,4,5-tetrahydropyridazine-3-carboxylic acid and 2,3-didehydroisoleucine.
通过降解研究和 1H 与 13C-NMR 光谱分析,阐明了卷曲霉素 A 和 B 的结构。研究结果表明,卷曲霉素 A 和 B 是一种七肽,含有三个不同寻常的新氨基酸,即羟甲基丝氨酸、2,3,4,5-四氢哒嗪-3-羧酸和 2,3-二脱氢异亮氨酸。
