Cytotoxic activity of 1 and 2 against human cancer cell lines [MCF-7 (breast), HeLa (cervical), MIA-PA-CA 2 (pancreatic), A-498 (kidney), Hep-G2 (hepatoma)] was evaluated by SRB assay.
Additionally, <i>in vitro</i> anticancer activity of the complexes were evaluated by SRB assay on selected cancer cell lines viz., HeLa (cervical), MIA-PA-CA-2 (pancreatic), MCF-7 (breast), Hep-G2 (Hepatoma), and SK-OV-3 (ovarian) which exhibited the superior cytotoxicity of complex [C<sub>31</sub>H<sub>35</sub>O<sub>4</sub>SeRuCl] as compared to other analogs on selective cancer phenotypes.Communicated by Ramaswamy H.
