Synthetic Route of 37366-09-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer. In a document type is Article, introducing its new discovery.
Ru(ii) polypyridine complexes which can undergo photo-induced ligand dissociation and subsequent DNA covalent binding may potentially serve as photoactivated chemotherapeutic (PACT) agents. In this paper, three fluorinated dppz ligand coordinated Ru(ii) complexes (2-4) containing four monodentate pyridine ligands were studied. All complexes released one pyridine and covalently bound to DNA upon 470 nm irradiation. Compared with the parent complex [Ru(dppz)(py)4]2+ (1), 2-4 displayed enhanced phototoxicity but diminished dark cytotoxicity, more favorable for PACT application. Complex 3 is the most efficient one with IC50 values of about 8 muM toward HeLa and SKOV-3 cell lines, and also has a much higher IC50 value toward normal L-02 cells. Our results indicate that fluorination on the retaining ligand may be an efficient way to improve the drug activity of Ru(ii) PACT agents.
