title: Synthesis, electrochemical studies and anticancer activity of ferrocenyl oxindoles.
abstract: A series of (E) and (Z)-ferrocenyl oxindoles were prepared by coupling substituted oxindoles to ferrocenylcarboxyaldehyde in the presence of morpholine as a catalyst. The redox behavior of these isomers was determined by cyclic voltammetry. The effects of the oxindole derivatives on the migration of human breast cancer cells were evaluated using the wound-healing assay and the Boyden chamber cell-migration assay. The most potent Z isomers 11b (IC(50) = 0.89 microM), 12b (IC(50) = 0.49 microM) and 17b (IC(50) = 0.64 microM) could represent attractive new lead compounds for further development for cancer therapy.
