PREVENTION OF CISPLATIN TOXICITY AGAINST NORMAL CELLS BY COMPLEXATION WITH C60 FULLERENE

The aim of this study was to evaluate the toxicity of noncovalent nanocomplex of C60 fullerene with cisplatin (C60-Cis-Pt) against normal cells. The toxicity of the C60-Cis-Pt nanocomplex compared to the free Cis-Pt was studied by estimating kidney human embryonic (HEK293) cells viability using MTT assay and rat erythrocytes resistance to acid haemolysis. It was shown that free 40 µM Cis-Pt changed the morphology and reduced the viability of HEK293 cells, as well as increased the number of haemolyzed erythrocytes compared to the According to the investigated parameters analysis no cytotoxic effects of C60-Cis-Pt nanocomplex was observed at Cis-Pt equivalent concentration. The prevention of Cis-Pt toxic action against normal cells by its complexation with C60 fullerene opens the prospect of nanostructure usage as an effective cytoprotector and a target carrier in tumor cells..
