The 1,3-diaryltriazenido(p-cymene)ruthenium(II) complexes with a high in vitro anticancer activity

1,3-Diaryltriazenido(p-cymene)ruthenium(II) complexes exhibit remarkable cytotoxic activity against several human carcinoma cells with IC50 values in sub micro-molar range. They are up to 560-times more active than the non-coordinated 1,3-diaryltriazenes.87
