  • Patent number: 7635685
    Abstract: A novel group of aminoglycosides which share some structural features of currently available aminoglycosides with regard to the backbone, while also having significant structural differences, is disclosed. The similarity enables these aminoglycosides to be highly potent and effective antibiotics, while the significant differences enable these aminoglycosides to reduce or even block antibiotic resistance. The aminoglycosides of the present invention are suitable for inhibition of antrax lethal factor, hence are suitable for use as a cure for anthrax.
