In vitro effect of imatinib mesylate loaded on polybutylcyanoacrylate nanoparticles on leukemia cell line K562.

The study aimed to prepare imatinib mesylate-loaded polybutylcyanoacrylate (PBCA) nanoparticles and evaluate their efficacy on leukemia cell line K562. The formulation was prepared by miniemulsion polymerization technique. Nanoparticles were characterized by dynamic light scattering (DLS), spectrophotometry, Fourier transform infrared spectroscopy (FTIR), dialysis membrane, and 3-(4,5-dimethylthiazol-2-Yl)-2,5-diphenyltetrazolium bromide (MTT) techniques. Nanoscale particles with high encapsulation efficiency (86%) and physical entrapment of drug were observed. In addition, nanoparticles showed suitable drug retention capability and potentiate the cytotoxicity effects of imatinib mesylate. Findings of study suggested PBCA nanoparticles are promising carrier for imatinib mesylate delivery to leukemia cell line K562.
