Thiosemicarbazones of 2-amino-5-chlorobenzophenone and 3-aminobenzophenone(L~1-L~4) have been synthesized and their Cu(Ⅱ) complexes(1-4) were afforded via coordination with cupric chloride.All these compounds were characterized by UV-vis and IR spectroscopy together with CHN elemental analysis.NMR spectroscopy was also applied to characterize the ligands.In vitro chohnesterase inhibitory assays for the complexes(1-4) showed IC_(50) values less than 10μmol/L,with complex 1 exhibiting the most activity,IC_(50)=2.15μmol/L and 2.16μmol/L for AChE and BuChE,respectively. Molecular modeling simulation revealed the binding interaction template for complex 1 with the AChE and BuChE receptors.In DPPH assay,the complexes also showed more in vitro antioxidant activities in comparison to their parent ligands.
