Inclusion complexation with cyclodextrins

Inclusion of guest molecules into the hydrophobic cavity of various cyclodextrins changes the properties of these guest molecules, which can be used for a broad variety of applications. Prediction models obtained from QSAR studies lead to a better understanding of the inclusion mechanism. A special feature of such complexation is the enthalpy-entropy compensation and pronounced solubility enhancements, which are used for better bioavailabilty of drugs and, in the case of biocides for a reduction of the biologically active compounds by equal activity.
