- 論文の詳細を見る
During the screening for inhibitors of K88 antigen synthesis that suppress hemagglutination by E. coli E68 NIH 457-71, we found Streptomyces sp. No. 207 produced two active substances, one of which was identified as hygromycin A. Another new compound, named methoxyhygromycin, was very similar to hygromycin A but methoxyhygromycin had a methoxy group on the neoinosamine-2 moiety instead of the methylene dioxy group found in hygromycin A. Although hygromycin A and methoxyhygromycin had almost no effect on the growth of E. coli E68 NIH 457-71, they inactivated the hemagglutination activity of E. coli at low concentrations of 12.5 μg/ml and 25 μg/ml, respectively.
