In vivo study of novel nanocomposite for prostate cancer treatment

Because of high occurrence of side effects of conventional anticancer drugs, new therapies have been widely studied, such as the use of non-usual molecules and the association with nanomaterials. In this context, sildenafil is a molecule that has been lately considered as a co-adjuvant in cancer therapy because it inhibits an enzyme with a potential role in tumor progression, phosphodiesterase-5. Taking into account the combination of nanoparticles and sildenafil, we produced systems based on mesoporoussilica nanoparticles, Pluronic F-127 and sildenafil as the main therapy for prostate cancer.
