Classical QSAR and comparative molecular field analyses of the host-guest interaction of organic molecules with cyclodextrins
TLDR
The application of classical QSAR and molecular modeling analysis using Comparative Molecular Field Analysis (CoMFA) to the complexation of some natural and modified cyclodextrins (CDs) with guest molecules was examined. Expand
