Nineteen antimony(III) complexes were obtained and examined as possible herbicides. Six of these were synthesized for the first time, and their structures were identified using elemental analyses, 1H-NMR, 13C-NMR, FTIR, LCMS, magnetic susceptibility, and conductivity measurement techniques. For the nineteen examined antimony(III) complexes their most-stable forms were determined by DFT/B3LYP/LanL2DZ calculation method. These compounds were examined for effects on photosynthetic electron transfer and carbonic anhydrase activity of photosystem II, and glutathione reductase from chloroplast as well were investigated. Our results indicated that all antimony(III) complexes inhibited glutathione reductase activity of chloroplast. A number of these also exhibited good inhibitory efficiency of the photosynthetic and carbonic anhydrase activity of Photosystem II.
我们获得了 19 种锑(III)配合物,并将其作为可能的除草剂进行了研究。其中六种锑(III)配合物是首次合成的,并通过元素分析、1H-NMR、13C-NMR、FTIR、LCMS、磁感应强度和电导率测量技术确定了它们的结构。通过 DFT/B3LYP/LanL2DZ 计算方法确定了 19 种锑(III)配合物的最稳定形式。研究了这些化合物对光合电子传递和光合系统 II 的碳酸酐酶活性的影响,还研究了叶绿体中的谷胱甘肽还原酶。结果表明,所有锑(III)络合物都能抑制叶绿体谷胱甘肽还原酶的活性。其中一些锑(III)络合物对光合作用和光系统 II 的碳酸酐酶活性也有很好的抑制作用。
