Cis-Platin (CP) is a remarkably effective Pt-based anticancer drug, but it also exhibits severe toxic side-effects, including nephrotoxicity and ototoxicity. Previous studies conducted with mammalian model organisms have clearly demonstrated that the intravenous administration of N-acetyl-L-cysteine (NAC) or sodium thiosulfate
