## Abstract An inclusion complex of fenbufen with Ξ²βcyclodextrin (Ξ²βCD) in aqueous solution was characterized by ^1^HβNMR spectroscopy. The [1:1] stoichiometry was determined and a stability constant of several 1000s (__M__^β1^) was calculated. The geometry of the inclusion complex was established

β¦ Synopsis
The interaction of alpha-, beta- and gamma-cyclodextrins with the anthracycline antibiotics doxorubicin and daunorubicin was investigated by LC, circular dichroism (CD) and absorption spectroscopy. All studies were performed in aqueous media at different temperatures and pH values. The anthracyclines complex only with gamma-cyclodextrin. Lineweaver-Burk and Scott's plots were used to calculate the stability constants of the anthracycline-gamma-cyclodextrin inclusion complexes.
