Although the TSC Ru-arene complexes have been proven to have potential as effective anticancer drugs, their distinct modes of action and biological targets are still the focus of active research. In this Article, a series of TSC derivatives (L1–L9) and their corresponding Ru(II)-arene complexes (1–9) were synthesized and characterized. The cytotoxicity toward the SGC-7901 human gastric and BEL-7404 human liver cancer cell lines of these compounds was ...
