Streptosporangium albidum has been determined by spectral methods and chemical degradations such as 1,8-diazabicyclo[5,4,0]undec-7-ene (DBU)-methanol reaction, ozonolysis, and periodative oxidation. The antibiotic consists of a 30-membered polyhydroxy lactone ring, an alpha, beta-unsaturated ester group, an intramolecular hemiketal, an oligosaccharide (aculexitriose), a neutral sugar and an amino sugar. The
已通过光谱方法和化学降解方法(例如1,8-二氮杂双环[5,4,0]十一碳-7-烯(DBU)-甲醇反应,臭氧分解和化学降解)确定了Albidum链霉菌产生的aculeximycin(1)的平面结构。周期性氧化。抗生素由一个30元的多羟基内酯环,一个α,β-不饱和酯基,一个分子内的半缩酮,一个寡糖(阿奇西三糖),一个中性糖和一个氨基糖组成。阿古霉素的结构与链霉菌孢子菌产生的孢拉维啶的结构密切相关。我们认为aculeximycin和sporaviridins属于一类新的大环内酯类抗生素,这与链霉菌产生的多元醇大环内酯类药物不同。
