    nitroxide derivatives 4a-h. A lead compound 4f was discovered based on Ach-induced vascorelaxation assay. Further chemical modification based on this scaffold provided a new series of 2-substituted phenylnitronyl nitroxide derivatives 6a-s. The newly synthesized compounds 6a-s possess improved radical scavenger's activity based on PC12 cell survival assay. Compounds 6g,n,o, and s are some of the most
    为了开发具有增强的自由基清除剂性能的更有效的小分子,我们设计并合成了一系列硝酰基硝基氧衍生物4a-h。基于Ach诱导的血管舒张测定法发现了前导化合物4f。基于该支架的进一步化学修饰提供了一系列新的2-取代的苯基亚硝酰基硝基氧化物衍生物6a-s。基于PC12细胞存活测定法,新合成的化合物6a-s具有改善的自由基清除剂的活性。就NO,H(2)O(2)和OH的清除能力而言,化合物6g,n,o和s是一些最有效的化合物。2-取代的苯基亚硝基硝基氮氧化物具有较高的自由基清除活性,带有给电子基团(EDG)。相比之下,吸电子基团(EWG)引入芳环导致其自由基清除活性急剧下降。这些结果表明,芳香环的给电子基团(EDG)可能是影响这些化合物清除自由基行为的重要因素,清除自由基的能力很大程度上取决于苯环的位置和电子性质。取代基。新型的2-取代的硝酰基氮氧化物的增强的自由基清除能力可能是对抗ROS(活性氧)/ R

    constants of the oxygen transfer reaction of 2-(substituted phenyl)-4,5-dihydro-4,4,5,5-tetramethylimidazol-1-oxyl 3-oxides with nitric oxide have been measured by using liquid chromatography (h.p.l.c.). The Hammett ρ value (–0.37) indicates that electron-donating substituents favour the reaction. This can be explained by a mechanism which includes electron transfer to nitric oxide and can be rationalised by

  • Crystal structures and magnetic properties of two complexes synthesized from manganese and halogenophenyl-substituted nitronyl nitroxide
    作者:Chen-Xi Zhang、Xiang-Yu Zhao、Na-Na Sun、Yan-Ling Guo、Yuying Zhang

    One-dimensional complex (1), [Mn(hfac)(2)(NITPhF)](2) and one binuclear radical complex (2), [Mn(hfac)(2)(NITPhBr)](infinity) have been synthesized. Here hfac stands for hexafluoroacetylacetonate, NITPhF for 2-(4'-fluorophenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide, and NITPhBr for 2-(4'-bromophenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide). All the two precursors were prepared and characterized by single-crystal X-ray diffraction analysis, IR, and magnetic analysis. In complex 1, the NITPhF radical acts as a bridge ligand linking two Mn(II) ions through the oxygen atom of the N-O group to form cyclic dimer. The dimers further connect two oxygen atoms of uncoordinated nitroxides of two adjacent radicals and yield one-dimensional chain sections. Instead in complex 2, the Mn(II) ions are bridged by the NITPhBr radicals through their N-O groups giving infinite one-dimensional chains. Magnetic susceptibility measurements indicate that both complex 1 and 2 behave ferrimagnetically. The Mn(II) ions interact antiferromagnetically with the direct bonding nitroxide group of the radicals alt(h)ough the structures of two complexes are different. The magnetic behaviors can be satisfactorily explained on the basis of the structural data. (C) 2010 Elsevier B.V. All rights reserved.
