β-Cyclodextrin-grafted hyaluronic acid as a supramolecular polysaccharide carrier for cell-targeted drug delivery.
2021
Abstract β-Cyclodextrin (β-CD) was grafted onto hyaluronic acid (HA) in a single step to generate a supramolecular biopolymer (HA-β-CD) that was explored for targeted drug delivery applications. Along with its excellent biocompatibility, the prepared HA-β-CD exhibits not only exceptionally high loading capacity for the model drugs doxorubicin and Rhodamine B through the formation of inclusion complexes with the β-CD component, but also the capability of targeted drug delivery to cancerous cells with a high level of expression of CD44 receptors, attributable to its HA component. The polymer can release the drug under slightly acidic conditions. With all its attributes, HA-β-CD may be a promising cancer-cell-targeting drug carrier.
