Synergistic targeting of cancer and associated angiogenesis using triple-targeted dual-drug silica nanoformulations for theragnostics

Small. 2012 Nov 19;8(22):3476-89. doi: 10.1002/smll.201200874. Epub 2012 Aug 3.

Abstract

The targeting and therapeutic efficacy of dye- and dual-drug-loaded silica nanoparticles, functionalized with triple targeting ligands specific towards cancer and neoangiogenesis simultaneously, are discussed. This synergized, high-precision, multitarget concept culminates in an elevated uptake of nanoparticles by cancer and angiogenic cells with amplified proficiency, thereby imparting superior therapeutic efficacy against breast cancer cells and completely disabling the migration and angiogenic sprouting ability of activated endothelial cells. The exceptional multimodal efficiency achieved by this single therapeutic nanoformulation holds promise for the synergistic targeting and treatment of the yet elusive cancer and its related angiogenesis in a single, lethal shot.

Keywords: angiogenesis; cancer therapy; drug delivery; mesoporous materials; nanoparticles.
