TATP-铜(Ⅱ)-氨基酸配合物的合成及其SOD活性
Synthesis and SOD-like activity of TATP-copper(Ⅱ)-amino acid complexes
【Abstract】 Two novel complexes [Cu(TATP)(L-Leu)(H2O)]NO3·H2O and [Cu(TATP)L-Met)(H2O)]NO3·0.5H2O(TATP=1,4,8,9-tetraazatriphenylene,L-Leu=L-Leucinate,L-Met=L-Methioninate)were synthesized and characterized by elemental analysis,molar conductivity,infrared absorption spectrum,electronic absorption spectrum and DTA-TGA.The results showed that both of the complexes had a distorted square-pyramidal geometry with two nitrogen atoms of TATP and one amino nitrogen and one carboxylate oxygen atoms of L-Leu/L-Met at the equatorial positions,and one water oxygen at the axial position.The SOD-Like activity of the complexes was determined by NBT-illumination method.The result indicated that the complexes possessed excellent SOD-like activity and showed 50% inhibition ration in the concentration of 0.355 μmol·L-1 and 0.185 μmol·L-1,respectively.The greater SOD-like activity of the complex[Cu(TATP)(L-Leu)(H2O)]NO3·H2O may be attributed to the smaller spatial hindrance of the side-chain group of L-Met.
