Background The present study is aimed to evaluate the physiochemical properties and cytotoxicity of mercury-based formulation for the development of anticancer therapeuticals. Methods The elemental and morphological features of the formulation were characterized by FESEM, XPS and EDS. The described formulation was evaluated for its cytotoxicity on Hek293 and MCF7 cell lines using MTT assay to study the in vitro effects. The in vivo developmental toxicity was also studied on zebrafish embryos and the lethal concentration (LC50) values were calculated as per the OECD regulations. Results The elemental and morphological characterizations confirmed the presence of mercuric compounds. The particles were spherical and stable with the size ranges between 20 and 80nm. Although the PK formulation contains mercurials it was very effective only to cancerous cells (MCF-7) and it is less toxic to normal cells (HEK 293). The in vivo assessment of developmental toxicity on zebrafish embryo confirmed the safer dosage of 100μg/ml. However, a higher dosage of 1mg/ml led to the malformation of embryos such as pericardial, tail and yolk sac edema. Conclusion The physiochemical characterization of PK formulation confirmed the presence of HgS. The results of both in vitro and in vivo studies showed that the formulation is less toxic. Although the test sample contains mercurials it was very effective against cancerous cells (MCF-7) and it is less toxic to normal cells (HEK 293).
