  • Patent number: 11446325
    Abstract: The present invention generally relates to use of single isomer chemically modified cyclodextrins, namely, S-(carboxyalkyl)-thio-cyclodextrin salts in medication used for the prevention or treatment of lysosomal storage diseases. More particularly, the present invention relates to isomer-pure, single isomer hexakis-S-(carboxyalkyl)-hexathio-alpha-cyclodextrin sodium salts, heptakis-S-(carboxyalkyl)-heptathio-beta-cyclodextrin sodium salts and octakis-S-(carboxyalkyl)-octathio-gamma-cyclodextrin sodium salts in medication used for the prevention or treatment of lysosomal storage diseases.

  • Publication number: 20220282001
    Abstract: Present invention relates to the protection of peptides and proteins against aggregation. The process and compositions according to the invention improve protein stability in presence of cyclodextrins without establishing any covalent interactions, only by inclusion and/or electrostatic phenomena. The carbohydrate compositions provide a temporary local molecular coating on the surface of protein macromolecules, via physical glycosylation.
