Targeted Release

Background: Doxorubicin, as a strong anti-cancer agent for clinical treatment of various cancer types along with other drugs, is widely utilized. Due to the physiology of the human body and cancerous tissues, the applicability of doxorubicin is still limited and the targeted treatment of the different types of cancers is considered. Also, the side effects of the conventional forms of chemotherapy medicines, damaging and stressing the normal cells are considerable. Objective: This study introduces a novel and effective system for the targeted release of doxorubicin by successfully fabricating the green magnetic graphene oxide, chitosan, allium sativum, and quercus nanocomposite. Methods: The in vitro release of doxorubicin loaded on the nanocomposite was evaluated and investigated at pH 7.4 and 6.5, respectively. The drug diffusivity in the plasma environment was assessed for a more accurate analysis of the drug diffusion process. The nanocomposite loaded drug release mechanism and kinetics, as well as cytotoxicity assay was investigated. Results: The efficiency of the drug encapsulation was significantly enhanced using natural extract ingredients and consequently, the efficacy of the targeted treatment of cancerous tissues was improved. The developed nanocomposite provided a controlled release of doxorubicin in similar acidic conditions of the normal and cancerous cells and affirming that the fabricated system is thoroughly pH-dependent. Conclusion: The cytotoxicity assay confirmed that the fabricated nanocomposite at a high growth rate of cancerous cells has an anticancer property and acts as a toxic agent against tumor cells, suggesting that in conjunction with doxorubicin, it can be highly improved for killing cancerous cells.
