  金纳米粒子引发的自由基氧化和卤素抽象。

  摘要：

  我们报告了使用EPR光谱和自旋捕获技术来检测在金纳米粒子的存在下形成的自由基中间体。发现被膦和胺保护的金纳米颗粒会引发空气中含有活性氢原子的有机底物的空气氧化，例如胺和氧化膦。受较强结合的配体（例如硫醇）保护的纳米颗粒在这些反应中没有活性。我们还发现，金纳米颗粒能够从卤代化合物中提取卤素原子，这可能是由于金金属对卤素的高度亲和力所致。金纳米粒子与氯仿的反应显示出不同寻常的反同位素效应。当金纳米粒子与CDCl（3）而不与CHCl（3）混合时，观察到三氯甲基自旋加合物。

  The correlation of lipid peroxidation with release of alkanes (RH) is considered a noninvasive method for the in vivo evaluation of oxidative stress. The formation of RH is believed to reflect a lipid hydroperoxide (LOOH)-dependent generation of alkoxyl radicals (LO.) that undergo, beta -scission with release of alkyl radicals (R-.). Alternatively, R-. could be spin-trapped with a nitrone before the formation of RH and analyzed by ESR. Extracts from the liver and lung of CCl4- and asbestos-treated rats that were previously loaded with nitrones exhibited ESR spectra suggesting the formation of iso-propyl, n-butyl, ethyl, and pentyl radical-derived nitroxides. In biological systems, various nitroxides with indistinguishable ESR spectra could be formed. Hence, experiments with N-tert-butyl-alpha -phenylnitrone (PBN) for spin trapping of R-. were carried out in which the nitroxides formed were separated and analyzed by HPLC with electrochemical detection (EC). The C1-5 homologous series of PBN nitroxides and hydroxylamines were synthesized, characterized by ESR, GC-MS, and HPLC-EC, and used as HPLC standards. For in vivo generation and spin trapping of R-., rats were loaded with CCl4 and PBN. The HPLC-EC chromatograms of liver extracts from CCl4-treated rats demonstrated the formation of both the nitroxide and hydroxylamine forms of PBN/(CCl3)-C-., as well as the formation of a series of unidentified PBN nitroxides and hydroxylamines. However, formation of PBN adducts with retention times similar to these of the PBN/C2-5 derivatives was not observed. In conclusion, we could not correlate the production of PBN-detectable alkyl radicals with the reported CCl4-dependent production Of C1-5 alkanes. We speculate that the major reason for this is the low steady-state concentrations of R-. produced because only a small fraction of LO. undergo,beta -scission to release R-..
