Abstract
Introduction: Nanocarriers have emerged as a powerful alternative for cancer therapy.Indeed, they are promising candidates to tackle the acquired resistance of surviving cells against antiproliferative drugs – the so-called multidrug resistance (MDR) phenomenon – which has arisen as one of the major clinical issues of chemotherapy. Among nanocarriers, this review focuses on the recent approaches based on tailored mesoporous silica nanoparticles (MSNs) that could overcome this problem. Areas covered: Herein we summarize the current efforts developed to provide MSNbased nanosystems of enhanced dual therapeutic action against diseased cells. This can be accomplished by three main approaches: i) increasing nanosystems’ killing capability towards particular cells by enhancing both recognition and specificity; ii)increasing the apoptotic effect throughout co-delivery of several drugs; or iii)combining drug delivery with apoptosis induced by physical methods.
Expert Opinion: The development of multifunctional nanosystems able to exert the optimal therapeutic action through the minimal administration constitutes a major challenge in nanomedicine. Recent developments in advanced MSN-based platforms for drug delivery represent promising avenues in the management of MDR associated with cancer therapy. All strategies discussed in this manuscript demonstrate improvements against difficult-to-treat tumors.
