AbstractTyrosine kinase inhibitors (TKIs) are new generation of anti-cancer drugs with very high efficiency against cancer cells. However, TKIs are associated with severe cardiotoxicity limiting their clinical benefits. One particular TKI that has been developed recently but not explored much is Ponatinib. The use of nanoparticles as a better therapeutic agent to deliver anti-cancer drugs and reduce their cardiotoxicity has been recently considered. In this study, PLGA-PEG-PLGA nanoparticles were synthesized to deliver Ponatinib while reducing its cardiotoxicity for treatment of chronic myeloid leukemia. Shape, size, surface charge and drug uptake ability of these nanoparticles were assessed using transmission electron microscopy (TEM), ZetaSIZER NANO and high-performance liquid chromatography (HPLC). Cardiotoxicity of Ponatinib, unloaded and loaded PLGA-PEG-PLGA nanoparticles were studied on zebrafish model through measuring the survival rate and cardiac function parameters, to optimize efficient drug concentrations in an in vivo setting. These particles were tested on zebrafish cancer xenograft model in which, K562 cell line, was transplanted into zebrafish embryos. We showed that, at an optimal concentration (0.0025mg/ml), Ponatinib loaded PLGA-PEG-PLGA particles are nontoxic/non-cardio-toxic and are very efficient against cancer growth and metastasis.
