  • Patent number: 11839658
    Abstract: The present invention relates to conjugates of aminoglycosides and terpenoids, in particular sesquiterpenoids. Furthermore, the present invention relates to nano-assemblies formed by the inventive conjugates and to a method for producing the conjugates and/or the nano-assemblies. The present invention also relates to the inventive conjugates and nano-assemblies for use in therapy, in particular for use in the treatment of infectious diseases. Particularly preferred embodiments of the present invention relate to farnesylated aminoglycosides and nano-assemblies thereof, in which farnesol and its derivatives do not only function as carrier for the aminoglycosides but do themselves have pharmaceutical activity upon cleavage of the conjugate, in particular quorum sensing inhibitory activity.
