Synthesis of 7, a ferrocene derivative of the antiestrogenic drug hydroxytamoxifen bearing a basic chain-O(CH2)nN(CH3)2 with n=4 is presented, together with both studies of its antiproliferative effect on the hormone-dependent MCF7 cell line (estrogenreceptor positive cells) and of its genotoxicity. This molecule is easily prepared via a McMurry coupling reaction. The antiproliferative effect found
A route to the organometallic complex 8 is described, along with a study of its antiproliferative effects on breast cancer cell lines; in the examples studied, 8 behaves in a very similar manner to tamoxifen, suggesting new possibilities for applications in organometallicchemistry.
