METHOD FOR THE PRODUCTION OF LARGE-RING CYCLODEXTRINS

Today’s cyclodextrin is a great patent on unusual CDs: large-ringed ones. The systematic experimental study of the properties of the large-ring cyclodextrins (LR-CDs) as host systems was hampered for a long time by the inability to obtain individual LR-CDs in quantities necessary for experimental examinations. Breakthrough in the situation was a recent patent and reports of Sophie Beeren and coworkers from DTU – Technical University of Denmark

Now we have a scalable method, and the isolation of the product does not require chromatography. And what should we do with these CDs? Let’s start by looking into analytical, biotech, and pharma applications. Then we shall see…

WO2024042228 METHOD FOR THE PRODUCTION OF LARGE-RING CYCLODEXTRINS (wipo.int)

Adenovirus formulation

This recent patent from our friend Tao Peng at Roquette on preserving an adenovirus vaccine with the help of cyclodextrins got us thinking about how CDs can be used in this area.

In the context of vaccines, cyclodextrins can effectively encapsulate antigens, ensuring their protection from degradation and improving their immunogenicity. Cyclodextrins offer stability advantages to vaccines by preventing the degradation of labile vaccine components during storage and transportation. Furthermore, cyclodextrins can serve as adjuvants, potentiating the immune response triggered by vaccines. Their unique structure and interaction with the immune system enhance the recognition of antigens by immune cells, leading to an improved activation of both innate and adaptive immune responses. This adjuvant effect contributes to the development of robust and long-lasting immune protection against targeted pathogens. Owing to the distinctive attributes inherent to nanoparticles, their integration into vaccine formulations has assumed an imperative role. Through the encapsulation of vaccine antigens/adjuvants within cyclodextrin nanoparticles, the potency and stability of vaccines can be notably enhanced. In particular, the capacity of amphiphilic cyclodextrins to form nanoparticles through self-assembly without surfactants or co-solvents is a captivating prospect for their application as carrier systems for antigens. In conclusion, cyclodextrins present a promising platform for enhancing the efficacy and stability of vaccines. Their ability to encapsulate antigens, stabilize labile vaccine components and act as adjuvants demonstrates their potential to revolutionize vaccine formulation and delivery. Further research and development in this field will facilitate the translation of cyclodextrin-based vaccine technologies into practical and impactful immunization strategies, ultimately benefiting global health and disease prevention.

Induction of Exocytosis Rescues Lysosomal GM2 Accumulation in Tay-Sachs Disease

Tay-Sachs disease, a progressive neurodegenerative disorder caused by mutations in the HEXA gene, lacks effective treatment. This study explores the therapeutic potential of δ-tocopherol and hydroxypropyl-β-cyclodextrin, targeting lysosomal exocytosis in Tay-Sachs models. Results indicate significant lysosomal GM2 reduction, offering hope for future treatments.
