Ovarian cancer activity of cyclic amine and thiaether metal complexes.

A thiaether metal complex 1-aza-4,7-dithiacyclononane-RhCl3, 2, and cyclic amine metal complexes tacn-CuBr2, 3, and Me3tacn-RuCl3, 4, have been evaluated for anticancer activity against the ovarian cancer cell line NuTu-19 and for cell toxicity against the noncancerous ovarian tissue cell line OVepi. Specifically, metal complex 2 is active when compared to cisplatin at micromolar concentrations using the MTT and cell invasion assay. The in vitro results reported warrant further evaluation of metal complex 2 in living systems.
