1N-({60 -Hydroxy-{107 -aminoalkanoyl)-6{40 N-methyl-3{40 ,4{40 -dideoxykanamycin B and the production thereof

摘要

A number of 1N-( alpha -hydroxy- omega -aminoalkanoyl)-6'N-methyl-3',4'-dideoxykanamycin B derivatives have been found to possess excellent antibacterial activity against most kanamycin susceptible and resistant organisms. In particular, 1N-(DL-isoseryl)-6'N-methyl-3',4'-dideoxykanamycin B, 1N-(L-isoseryl)-6'-N-methyl-3',4'-dideoxykanamycin B, 1N-(L-4-amino-2-hydroxybutyryl)-6'N-methyl-3',4'-dideoxykanamycin B and 1N-(L-5-amino-2-hydroxyvaleryl)-6'N-methyl-3',4'-dideoxykanamycin B, or an acid addition salt thereof possess these highly desirable attributes.
