Abstract

The major limitation of traditional chemotherapeutic agents is their poor selectivity for cancer cellsand their severe toxicity to normal cells. Therefore, localized drug delivery would, ideally, improve thetherapeutic efficacy, minimizing side effects. The properties of mesoporous silica nanoparticles (MSNs)seem to cope with this aim. A MSN-based device, FOL-MSN-BTZ, bearing the antineoplastic drugbortezomib (BTZ), linked to MSNs by means of a pH-sensitive bond and the folic acid (FOL, a targetingfunction), was then developed and tested on folate receptor (FR+ cells) overexpressing cancer cells andon FR- normal cells, in order to investigate MSNs behaviouor.
