Paclitaxel (PTX) was complexed with beta-cyclodextrin (1), 2,6-dimethyl-beta-cyclodextrin (2) and 2,3,6-trimethyl-beta-cyclodextrin (3). PTX-CYD complexes were characterized both at the solid and liquid states. Experimental findings are in agreement, with molecular modeling analysis, which showed different PTX-CYD interaction as a function of macrocyle methylation. The complexation of PTX within the CYD cavity preserved its antitumoral activity.

Abstract
Paclitaxel (PTX) was complexed with beta-cyclodextrin (1), 2,6-dimethyl-beta-cyclodextrin (2) and 2,3,6-trimethyl-beta-cyclodextrin (3). PTX-CYD complexes were characterized both at the solid and liquid states. Experimental findings are in agreement, with molecular modeling analysis, which showed different PTX-CYD interaction as a function of macrocyle methylation. The complexation of PTX within the CYD cavity preserved its antitumoral activity.
