Modification of the estrogenic properties of diphenols by the incorporation of ferrocene. Generation of antiproliferative effects in vitro
Résumé
We report here the synthesis and the strong and unexpected antiproliferative effect of the organometallic diphenolic compound 1,1-bis(4'-hydroxyphenyl)-2-ferrocenyl-but-1-ene (4) on both hormone-dependent (MCF7) and -independent (MDA-MB231) breast cancer cells (IC50 = 0.7 and 0.6 mu M). Surprisingly, 6 [1,2-bis(4'-hydroxyphenyl)-2-ferrocenyl-but-1-ene], the regioisomer of 4, shows only a modest effect on these cell lines. This pertinent organometallic modification seems to trigger an intracellular oxidation of the structurally favorable compound 4, leading to the generation of a potent cytotoxic compound.
