一些四氢异吲哚-1,3-二酮衍生物(TDDS)具有很强的除草活性。为了评估TDDS对人体的可能影响,用稳态和时间分辨荧光光谱、同步荧光光谱、傅里叶变换红外光谱和圆二色谱研究了TDDS与人血清白蛋白(HSA)之间的相互作用。在298、307和316K温度下得到的热力学数据表明,TDDS会自发地与HSA结合,从而形成TDD-HSA络合物。TDDS改变了人血清白蛋白的构象和二级结构,使人血清白蛋白的本征荧光被静态猝灭。此外,TDD-HSA络合物主要是通过静电作用形成的,在HSA上只有一个结合部位。竞争性配基结合分析表明,位点II(亚区IIIA)对TDDS的亲和力最强。此外,急性毒性生物测定表明,斑马鱼暴露于4000μg L-1的TDDS时没有死亡。这项工作有助于理解TDDS和HSA之间的相互作用。
Some tetrahydroisoindoline-1,3-dione derivatives (TDDs) possess potent herbicidal activity. To assess possible impacts of TDDs on humans, the interactions between TDDs and human serum albumin (HSA) were evaluated with steady-state and time-resolved fluorescence spectroscopy, synchronous fluorescence spectroscopy, Fourier transform-infrared spectroscopy, and circular dichroism spectroscopy. The thermodynamic data obtained at temperatures of 298, 307, and 316 K indicate that TDDs spontaneously bind to HSA and thus form a TDD-HSA complex. The conformation and secondary structure of HSA are changed, and the intrinsic fluorescence of HSA is statically quenched by TDDs. Moreover, the TDD-HSA complex is formed primarily through electrostatic interactions and has only one binding site on HSA. A competitive ligand-binding assay revealed that site II (subdomain IIIA) displays the greatest affinity for TDDs. In addition, an acute toxicity bioassay showed no zebrafish mortality upon exposure to 4000 μg L-1of TDDs. This work is helpful for understanding interactions between TDDs and HSA.
