Multiple modifications (X) are tolerated at the ribofuranosyl 5-position in neomycin B and the apralogs, but only amine-based derivatives are active in the paromomycins, propylamycins and ribostamycins. This is discussed in terms of total amino group count and the ring 1 functionality, amino or hydroxy, with amino groups at the 6’- and 7’-positions in the neomycins and apralogs conferring greater flexibility
