Description

General description

Gamma-cyclodextrin (γ-CD) is a cyclic α-1,4-glucan linked oligosaccharide that is widely used in the food and pharmaceutical industries. In drug delivery, γ-CD can be used as a complexing agent because it forms an inclusion complex with a drug molecule. The complex of cyclodextrin increases the aqueous solubility and dissolution rate of the drug, which is useful for the delivery of the medical agent to a biological system.

Application

γ-Cyclodextrin can be used as a precursor for the synthesis of:

• Octakis-(2,3-di-O-methyl-6-O-carboxymethyl)-γ-cyclodextrin sodium salt (ODMCM). ODMCM is used in capillary electrophoresis as a chiral resolving agent.
• Water-soluble cyclodextrin thioethers derivatives for the transportation of hydrophobic drugs.
