“…When coordinated to metal ions, promising results were obtained and some compounds show a range of biological activities (Zhou et al, 2001;Chen et al, 2009;Wang et al, 2006;Naso et al, 2010;Durgo et al, 2011;Pereira et al, 2007;Etcheverry et al, 2008;Ferrer et al, 2006). Hydroxamic acid and its derivatives coordinate to a wide variety of transition metal ions either as monoanionic hydroxamate or dianionic hydroximate O,O 0 -bidentate ligands and have also been of interest in applications in medicine (Codd, 2008;Sresutharsan et al, 2017;Adiguzel et al, 2017); it is considered by the research community as an important anticancer therapy candidate (Pal & Saha, 2012). One of the most significant uses of hydroxamic acids, however, is for the treatment of iron-overload disease and, due to some shortcomings of current drugs, much research is focused in this field (Kalinowski & Richardson, 2005;Chaston & Richardson, 2003;Li et al, 2004;Zheng et al, 1985;Tacke et al, 2000;Casellato et al, 1984).…”
