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.
