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 (estrogen receptor positive cells) and of its genotoxicity. This molecule is easily prepared via a McMurry coupling reaction. The antiproliferative effect found for 7 at an incubation molarity of 1 μM was very close to that found for the usual reference molecule, namely OH-tamoxifen. In addition to its structural antiestrogenic effect, 7 showed cytotoxic activity probably due to the vectored ferrocene. This genotoxic component was confirmed by a 3D (damaged DNA detection) test, that permits identification and quantification of lesions induced on DNA. Some key interactions of 7 docked into the alpha-estrogen receptor binding site were also shown.

As part of the search for tamoxifen substitutes that could be useful in the treatment of breast cancer, the use of organometallic complexes has been investigated.For this purpose a synthesis has been developed for ferrocifen, the prototype of this new series of complexes.Low valent titanium-mediated (TiCl4/Zn) cross-coupling of 4-MeO-C6H4COPh with ferrocenyl ethyl ketone affords the corresponding but-1-ene in high yield (66percent), from which ferrocifen, 3, is rapidly prepared in an overall yield of 41percent.Keywords: Ferrocifen; Ferrocene; Tamoxifen; Anti-tumour
