a saccharide radical being substituted by an alkylamino radical in position 3 and by two substituents different from hydrogen in position 4, e.g. gentamicin complex, sisomicin, verdamycin

Full Title

Compounds containing hydrocarbon or substituted hydrocarbon radicals directly attached to hetero atoms of saccharide radicals > Carbocyclic rings > Cyclohexane rings, substituted by nitrogen atoms > Cyclohexane rings substituted by at least two nitrogen atoms > with at least two saccharide radicals directly attached to the cyclohexane rings > attached to non-adjacent ring carbon atoms of the cyclohexane rings, e.g. kanamycins, tobramycin, nebramycin, gentamicin A2 > a saccharide radical being substituted by an alkylamino radical in position 3 and by two substituents different from hydrogen in position 4, e.g. gentamicin complex, sisomicin, verdamycin
