Although supramolecular prodrug self-assemblies have been proven as efficient nanocarriers for cancer therapy,tedious synthesis procedures have made their practical applications more difficult. In this paper, β-cyclodextrinbased supramolecular self-assemblies (SSAs) were directly constructed by utilizing β-cyclodextrin trimer (β-CD3)as the host unit and unmodified curcumin as the guest unit. Due to the adjustment of host-guest inclusion and hydrophilic-hydrophobic interactions occurring in the SSAs, their morphology could be readily tuned by changing the ratio of the two components. Different self-assembly morphologies, such as spherical complex micelles, spindle-like complex micelles and multi-compartment vesicles, were obtained. Furthermore, basic cell experiments were performed to study the corresponding effects of the SSA shape on their biological properties. Compared to the other micelles, the spindle-like complex micelles exhibited enhanced cellular toxicity, uptake behaviors and apoptosis rates, and the spherical complex micelles exhibited poor performance. The performance of the multi-compartment vesicles was similar to that of the spindle-like complex micelles. The facile construction of these shape-regulated SSAs and their different cellular biological properties might be valuable in the controlled drug release field.
