  Unsymmetrical Azo Initiators Increase Efficiency of Radical Generation in Aqueous Dispersions, Liposomal Membranes, and Lipoproteins

  摘要：

  Lipid peroxidation studies often employ the use of azo initiators to produce a slow, steady source of free radicals, but the lack of initiators capable of efficiently generating radicals in lipid aggregates such as micelles and membranes has created persistent problems in these investigations. We report here the synthesis and study of unsymmetrically substituted (hydrophilic/hydrophobic) azo initiators C-8, C-12, and C-16 that increase the efficiency of radical generation in lipophilic regions of aqueous emulsions such as micelles and liposomes. Radical generation from these initiators was monitored in micelles? liposomes, and lipoproteins by the use of two radical scavengers, one that scavengers lipophilic peroxyl radicals and one that scavenges hydrophilic peroxyls. The lipophilic radical scavenger used was the well-known antioxidant alpha-tocopherol and thr hydrophilic radical scavenger used was uric acid. Two peroxyl radicals are trapped by each of these scavengers, tocopherol presumably being biased toward reacting with lipid soluble radicals, uric acid presumably reacting preferentially with water-soluble radicals. In Triton X-100 micelles the unsymmetrical initiators C-8 and C-16 display an increase in both alpha-TOH (alpha-tocopherol) trapping and in overall radical generation efficiency compared to the symmetrical initiators C-0 (hydrophilic) and MeOAMVN (lipophilic). The unsymmetrical azo initiators performance in liposomes was excellent (increased cage escape with lipid compartment access). In low-density lipoprotein oxidations, the initiators C-8, C-12, and C-16 also provided advantages over C-0 and MeOAMVN. The hydrophilic/hydrophobic character of the two radicals generated from the unsymmetrical initiators is an important factor for separating the geminate radical pair, These initiators, when compared to the widely used symmetrical azo initiators, provide an advantage of free radical production, lipophilic access, and constant radical generation in the investigation of lipid peroxidation in various media.

  基于两亲性Mn 2+的超分子组装体作为高弛豫性MRI探针† ‡

  摘要：

  在MRI造影剂（CA）的研究领域中，通常寻求两亲顺磁性络合物以增加血浆半衰期和高弛豫值，但是迄今为止已经报道了基于两亲Mn 2+的CA的有限实例。在这项工作中，包含一个或两个脂族链的六个原始两亲性配体（三个EDTA状配体和三个1,4-DO2A衍生物）的Mn 2+复合物被评估为潜在的MRI造影剂并进行了比较。由于超分子聚集体的分子翻滚速率增加，强烈的自缔合成胶束导致弛豫性（r 1）增强（相对于MnEDTA约80％）。对于双取代系统，由于螯合剂围绕脂肪族侧链的局限旋转，r 1的增益要高得多（r 1在12.6-18.4 mM -1 s -1的范围内，是单链胶束的2-3倍EDTA系统）。此外，这些两亲性螯合物以10 4 –10 5 M -1的缔合常数K A与人血清白蛋白（HSA）紧密结合。所得的超分子加合物达到了显着的弛豫值，对于MnEDTA状螯合物而言，在50-60 mM -1 s -1范围内，在27-30
