Ruthenium pincer complexes for light activated toxicity: Lipophilic groups enhance toxicity.

ABSTRACT: Nine ruthenium CNC pincer complexes (1-9) were tested for anticancer activity in cell culture under both dark and light conditions. These complexes included varied CNC pincer ligands including OH, OMe, or Me substituents on the pyridyl ring and wingtip N-heterocyclic carbene (NHC) groups which varied as methyl (Me), phenyl (Ph), mesityl (Mes), and 2,6-diisopropylphenyl (Dipp). The supporting ligands included acetonitrile, Cl, and 2,2'-bipyridine (bpy) donors. The synthesis of complexes 8 and 9 is described herein and are fully characterized by spectroscopic (¹H NMR, IR, UV-Vis, MS) and analytical techniques. Single crystal X-ray diffraction results are reported herein for 8 and 9. The other complexes (1-7) are reported elsewhere. The four most lipophilic ruthenium complexes (6,
