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.
