  Influence of the Structure on the Antioxidant Activity of Tetradentate Schiff Bases and their Copper(II) Complexes: Possible Mechanisms

  摘要：

  The influence of the structure on the antioxidant activity of a series of Schiff bases and their copper(II) complexes as well as possible mechanisms of antioxidant activity were investigated. Schiff bases are derived from the condensation of ethane-1,2-diamine or propane-1,2-diamine and pentane-2,4-dione and/or 1-phenylbutane-1,3-dione. The corresponding complexes were synthesized. The antioxidant activity in vitro, determined using reversed-phase thin layer chromatography assay (RP TLC) based on the reaction with 2,2'-diphenyl-1-picrylhydrazyl, was expressed as Trolox equivalent antioxidant capacity (TEAC). The influence of the structure was observed on the basis of interpretable and informative descriptors calculated by hybrid density functional theory (DFT) methods. Structural features responsible for the antioxidant activity of the investigated compounds were discussed. Copper(II) complexes showed a significantly higher antioxidant activity than their corresponding ligands. Calculated quantum-chemical descriptors gave an insight to the reaction mechanism of the scavenging/antioxidant activity of tetradentate Schiff bases and their copper(II) complexes and two different reaction mechanisms were proposed.

  二氮杂s。第V部分2,3-二氢-1 H -1,4-二氮杂s

  摘要：

  当将β-二酮和脂肪族1,2-二胺的等摩尔混合物在乙酸中加热时，会形成2,3-二氢-1 H -1,4-二氮杂derivatives衍生物。但是，如果将这些反应物的2：1混合物保持在室温下（无论是在醇中还是在无溶剂中），都将产生开链缩合产物。甘氨酰胺与乙酰丙酮反应生成偶氮甲碱而不是二氮杂pine。过氢的1,4-二氮杂pine不能脱氢成二氢二氮杂pine。2，3-二氢-1 H -1,4-二氮杂吡啶鎓阳离子非常稳定，这是由二氮杂的p K值及其对高锰酸盐氧化的相对稳定性所证明的。

  Two pairs of enantiomeric oxovanadium(IV) complexes of the fluorinated Schiff base 1,2-propylenebis(trifluoroacetylace-toneimine) were separated chromatographically and the absolute configurations tentatively assigned. The complexes were found to be stable to diastereoisomeric conversion about the carbon chiral centre at 200 degrees C but were sensitive to such conversion about the oxovanadium(IV) chiral centre at considerably lower temperatures. Moisture and traces of free ligand appear to hasten this process. (C) 2000 Elsevier Science S.A. All rights reserved.
