Toxicity of ruthenium
WebNov 1, 2024 · Anticancer potential of ruthenium complexes has been widely investigated, but safety evaluation studies are still scarce. Despite of ruthenium-based anticancer agents are known to cause fewer side effects compared to other metal-based drugs, these compounds are not fully free of toxicity, causing mainly nephrotoxicity. WebThis toxicity was not limited to ruthenium complexes as many cationic metal-polypyridyl complexes induced neurotoxic symptoms in mice.[11] In general, doses higher than 18 mg complex/kg mouse were lethal and in many cases doses as low as 3 mg/kg were lethal.
