Abstract:

A series of ruthenium(Ⅱ) rectangular macrocyclic assemblies(4—12) was synthesized by half-sandwich ruthenium(Ⅱ)(Ru1Ru3) and 1,3-diimidazolebenzene ligands(13). The composition and structure of assemblies 4—12 were determined by nuclear magnetic resonance spectroscopy, high resolution mass spectroscopy, elemental analysis and single crystal X-ray diffraction. The toxicity of these ruthenium(Ⅱ) assemblies 4—12 to four human tumor cell lines was studied by MTT experiments, and it was found that the oxalic and benzoquinone ruthenium assemblies 4—9 exhibited little cytotoxic activity against the tumor cell lines(IC50>100 μmol/L), except that naphthoquinone ruthenium assemblies 10—12 showed good cytotoxic activity against all tested tumor cell lines(IC50<2.22 μmol/L). The acute toxicity experiment of zebrafish eggs showed that the toxicity of the assembly 12 was lower, and the tumor experiment in the zebrafish showed that the assembly 12 had a better anti-cancer effect in the organism. The results showed that the main interaction between Ru assembly and DNA was insertion.

Key words: Half-sandwich ruthenium(Ⅱ), Ruthenium(II) rectangular macrocyclic assembly, Anti-cancer activity
