چکیده

Ten molecularly diverse compounds, selected on the basis of the standard free energy of complexation with β-cyclodextrin, have been used as training set of molecular docking experiments. After the conformational search of each compound the Molecular Interaction Evaluation (MOLINE) program has been adopted to generate the inclusion geometries. The recognition process has been thermodynamically evaluated by the computational method, theoretical and experimental free energies of complexation have been compared obtaining an high correlation (r > 0.9). A statistical and graphical analysis of the binding inclusion geometries completed the work.

Evaluation of Some Methods for Preparing Glipizide-β-Cyclodextrin Inclusion Complexes

      Glipizide has been found to form inclusion complexes with β-cyclodextrin (β-CD) in solution and in solid state. The present study was undertaken to determine a suitable method for scaling up glipizide-β-CD inclusion complex formation and to evaluate the effect of some parameters on the efficiency of complexation. The solid inclusion complexes of glipizide and β-CD were prepared at a molar...
