“…A thorough survey of the literature has revealed that the structure-activity relationship has been studied for cobalt [33], copper [34,35], iron [36], vanadyl [37], platinum [38][39][40][41][42][43][44] and ruthenium [45] complexes with diverse ligands. The biological properties related to the structure are the anticancer activity [38,39], the antimicrobial activity [35][36][37] and the DNA-binding [33][34][35][36][37][40][41][42][43][44] since the interaction with DNA may be a principal target of metals or complexes in the cancer cells [46][47][48][49].…”
