“…1 The bio-organometallic chemistry of ferrocene based compounds with biomolecules 2 is also today intensively studied: 3,4 the main properties of the ferrocene unit in these compounds, related to their biological activity, are the small size, the high stability in aqueous and aerobic media, the relative lipophilicity, and the peculiar redox behavior. In the literature complex ferrocene derivatives with biological activity such as antifungal, [5][6][7][8][9][10][11][12][13] antimalerial, 14 anticancer, 15 antimicrobial, 16 anti-HIV-1, 17 antioxidant, 18 and PDE4 inhibitory activities 19 etc. are often reported, but it is important to underline that ferrocene itself exhibits interesting properties such as antianemic, 20 antiseptic, 21 or cytotoxic activities.…”
