Mechanism of action

Cyclodextrins are cyclic oligosaccharides with a hydrophobic cavity that can encapsulate poorly water-soluble compounds, increasing their solubility and stability. Hydroxypropyl-beta-cyclodextrin (HPβCD) is used as a pharmaceutical excipient to facilitate the formulation and delivery of drugs that would otherwise have limited aqueous solubility. In the context of Cyclo Therapeutics' development, HPβCD is being investigated as a therapeutic agent itself for certain lysosomal storage disorders where it may help mobilize and clear accumulated lipids.
