Cytotoxicity of 6-Mercaptopurine via Loading on PVA-Coated Magnetite Nanoparticles Delivery System: A New Era of Leukemia Therapy

Moustafa ME, Amin AS and Magdi Y

Fe₃O₄ were synthesized via chemical co-precipitation method in which NH₄OH acted as reducing agent to obtain water-dispersible, biocompatible, magnetite (Fe₃O₄) nanoparticles. The latters were coated with polyvinyl alcohol (PVA) and 6-Mercaptopurine (6-MP) drug was then loaded into the surface of PVA-coating- Fe₃O₄ nanoparticles. The structural, morphological and magnetic characterization of the uncoated, coated and 6-MP loaded iron oxide nanoparticles are presented here. The particles were characterized by XRD, HR-TEM, TGA, FTIR and vibrating sample magnetometer (VSM). Cytotoxicity of 6-Mercaptopurine loaded into PVA-coated magnetite nanoparticles as a new era of leukemia therapy was studied aiming to improve its therapeutic effects by decreasing its dose as well its side effects.
