“…It has demonstrated anticancer activity and could be a formulant in innovative anticancer drugs [ 17 , 18 , 19 ]. Copper(II) complexes, such as hydroxytryptophan copper(II) [ 20 ], substituted derivatives of pregnenolone acetate copper(II) [ 21 ], thiosemicarbazone copper(II) [ 22 ], substituted carboxylic acid copper(II) [ 23 ], 1,10-phenanthroline derivative copper(II) [ 24 ], pyridine derivative copper(II) [ 25 ], thiosemicarbazone copper(II) [ 26 ], piperazine copper(II) [ 27 ], and schiff copper(II) [ 28 ], have been synthesized, and their anticancer efficacy has been assessed.…”
