Synthesis and Characterization of ZIF-90 Nanoparticles as Potential Brain Cancer Therapy.

ABSTRACT: Human glioblastoma is probably the most malignant and aggressive among cerebral tumors, of which it represents approximately 80% of the reported cases, with an overall survival rate that is quite low. Current therapies include surgery, chemotherapy, and radiotherapy, with associated consistent side effects and low efficacy. The hardness in reaching the site of action, and overcoming the blood-brain barrier, is a major limitation of pharmacological treatments. In this paper, we report the synthesis and characterization of ZIF-90 (ZIF, Zeolitic Imidazolate Framework) nanoparticles as putative carriers of anticancer drugs to the brain. In particular, we successfully evaluated the biocompatibility of these nanoparticles, their stability in body fluids, and their ability to uptake in U251 human glioblastoma cell lines. Furthermore, we managed to synthesize ZIF-90 particles loaded with berberine, an alkaloid reported as a possible effective adjuvant in the treatment of glioblastoma. These findings could suggest ZIF-90 as a possible new strategy for brain cancer therapy and to study the physiological processes present in the central nervous system.
