  Glycodiversification for the Optimization of the Kanamycin Class Aminoglycosides

  摘要：

  In an effort to optimize the antibacterial activity of kanamycin class aminoglycoside antibiotics, we have accomplished the synthesis and antibacterial assay of new kanamycin B analogues. A rationale-based glycodiversification strategy was employed. The activity of the lead is comparable to that of commercially available kanamycin. These new members, however, were found to be inactive against aminoglycoside resistant bacteria. Molecular modeling was used to provide the explanation. Thus, a new strategy for structural modifications of kanamycin class aminoglycosides is suggested.

  Using allylic azide rearrangement, a convenient method has been developed for the synthesis of 2′,3′-dideoxyaminoglycosides that are, otherwise, difficult to be prepared. The antibacterial activity of these novel aminoglycosides also confirms the indispensable role of 2′-NH2 group for both neomycin and kanamycin classes of aminoglycosides.
