초록

The present study was conducted to evaluate in vivo anticancer activity of two novel mononuclear ruthenium(II) compounds, namely Ru(1,10-phenanthroline)$_2$(2-nitro phenyl thiosemicarbazone)$Cl_2$(Compound $R_1$) and Ru (1,10-phenanthroline)$_2$(2-hydroxy phenyl thiosemicarbazone)$Cl_2$(Compound $R_2$) against Ehrlich ascites carcinoma (EAC) mice and in vitro cytotoxic activity against IEC-6 (small intestine) cell lines and Artemia salina nauplii using MTT [(3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide)] and BLT [brine shrimp lethality] assays respectively. The tested ruthenium compounds at the doses 2 and 4 mg/kg body weight showed promising biological activity especially in decreasing the tumor volume, viable ascites cell counts and body weights. These compounds prolonged the life span (% ILS), mean survival time (MST) of mice bearing-EAC tumor. The results for in vitro cytotoxicity against IEC-6 cells showed the ruthenium compound $R_2$ to have significant cytotoxic activity with a $IC_{50}$ value of $20.0{\mu}g/mL$ than $R_1$ ($IC_{50}=78.8{\mu}g/mL$) in the MTT assay and the $LC_{50}$ values of $R_1$ and $R_2$ compounds were found to be 38.3 and $43.8{\mu}g/mL$ respectively in the BLT assay. The biochemical and histopathological results revealed that there was no significant hepatotoxicity and nephrotoxicity associated with the ruthenium administration to mice.
