Thermoresponsive organometallic arene ruthenium complexes for tumour targeting

Application of mild hyperthermia can increase the cytotoxicity of anticancer drugs in tumour cells. In this report, we describe low molecular weight thermoactive ruthenium-based drugs with fluorous chains that are selectively triggered by mild hyperthermia. The organometallic complexes were prepared, characterized, and evaluated for their in vitro cytotoxicity against a panel of human cancer cell lines and non-cancerous immortalized cells. The compounds show considerable chemo-thermal selectivity towards cancer cells (ca. 5 mu M versus >500 mu M for healthy cells) for the compound with the longest fluorous chain.
