Synthesis and antibacterial activity of novel neamine derivatives

Synthesis and activity of derivatives at the O5 or O6 positions of 1-N-((S)-4-amino-2-hydroxybutyryl)-3′,4′-dideoxyneamine, which is the neamine moiety of arbekacin, were reported. Among these results, the 5-O-aminoethylaminocarbonyl derivative showed effective activity against Staphylococcus aureus expressing a bifunctional aminoglycoside-modifying enzyme AAC(6′)-APH(2″).
