Abstract
We present a novel, multicomponent nanoparticulate carrier system based on superparamagnetic iron oxide nanoparticles with a designed hydrophilic/hydrophobic balance based on oleic acid and TWEEN 80 to incorporate hydrophobic cannabinoids-cannabigerol and cannabidiol-as well as the hydrophilic anthracycline drug epirubicin, forming a conjugate anticancer system. Additionally, the superparamagnetic iron oxide-based nanoparticles formed the core of the system, thus providing it with magnetic hyperthermia capabilities with a specific absorption rate comparable to the corresponding systems in the literature. The interaction of the conjugate with the cell membrane was studied using the Langmuir monolayers at the air/water interface formed of selected lipids modeling the healthy and cancerous cell membranes. Finally, cytotoxicity tests were carried out against the SKOV-3 cell line in vitro. A synergistic effect was observed when both the cannabinoid and epirubicin were present in the conjugate, as compared to the cannabinoid or epirubicin alone, making our system advantageous for further development for tentative therapeutic use.
