On the encapsulation and assembly of anticancer drugs in a cooperative fashion.

ABSTRACT: In this study, we report the remarkable recognition and assembly characteristics of D _3h symmetric basket 1 ^6- containing two adjoining and nonpolar cavities with six biocompatible GABA residues at their northern and southern termini. From the results of experimental (¹H NMR, fluorescence and UV-Vis spectroscopies) and computational (MM-MC/OPLS3e) investigations, we deduced that hexaanionic 1 ^6- captured two molecules of anticancer drug doxorubicin 2 ⁺ in water and accommodated them in its two deep cavities. The formation of stable 1 ^6-⊂2 ₂ ²⁺ (K _a = 3 × 10¹² M^-2) was accompanied by the exceptional homotopic cooperativity
