Mitoxantrone (MTO) is a topoisomerase II inhibitor which has been used to treat various forms of cancer either as solo chemotherapy regimen or as component in cocktail treatments. However, as with other anti-neoplastic agents, MTO has severe cardiac side effects. Therefore, a drug delivery approach holds promise to improve safety and applicability of this chemotherapy. Here, we report the application of a plant virus-based nanotechnology derived from tobacco mosaic virus (TMV) as a delivery vehicle for MTO towards cancer therapy. TMV is a high aspect-ratio, soft-matter nanotube with dimensions of 300×18 nm and a 4-nm wide channel. The surface chemistry of the interior and exterior surfaces is distinct and we established charge-driven drug loading mechanisms to accommodate therapeutics inside the channel for drug delivery. We demonstrate effective MTO loading into TMV yielding ~ 1,000 MTO per TMV carrier. Treatment efficacy of MTO-loaded TMV (MTOTMV) was assessed in in-vitro and in-vivo models. In-vitro testing confirmed that MTO maintained its efficacy when delivered by TMV in a panel of cancer cell lines. Drug delivery in-vivo using a mouse model of triple negative breast cancer demonstrated superior efficacy of TMV-delivered MTO vs. free MTO. This study demonstrates the potential of plant virus-based nanotechnology for cancer therapy and drug delivery.
