  Synthesis of chroman analogues of lipoic acid and evaluation of their activity against reperfusion arrhythmias

  摘要：

  Novel hybrids of lipoic acid and trolox connected through triamine spacers as well as analogues in which the lipoic acid was attached at different positions of the chroman moiety of vitamin E through an amide bond, were synthesized and exhibited strong inhibition of the microsomal lipid peroxidation. Moreover, the new molecules, at 1 muM concentration, reduced reperfusion arrhythimas and MDA content on isolated rat heart preparations, with the 2- and 5-subtituted chromans possessing the better cardioprotective activity.

  numerous activities while its synthetic analogues were found to exhibit anticancer and anti-ischemic activity. However, the ability of tropolone derivatives to protect neuronal cells from oxidative stress-induced cell damage has not been studied so far. As an ongoing effort toward highly effective antioxidants with potential neuroprotective activity, we have synthesized 7-substituted derivatives of β-thujaplicin

  天然托酚酮β-修柏灵（扁柏酚或2-羟基-4-异丙基-2,4,6-环庚三烯-1-酮）具有多种活性，而其合成类似物具有抗癌和抗缺血活性。然而，到目前为止，托酚酮衍生物保护神经元细胞免受氧化应激诱导的细胞损伤的能力尚未得到研究。为了努力开发具有潜在神经保护活性的高效抗氧化剂，我们合成了β-thujaplicin及其甲氧基类似物的7-取代衍生物。取代基是杂环（哌嗪，吗啉）或杂芳族化合物（三唑，吡啶）。仅β-thujaplicin的哌嗪衍生物能够保护HT22海马神经元免受氧化应激诱导的细胞死亡。

  chromans substituted at positions 2 or 5 by catechol derivatives were synthesized, and their activity against oxidative stress induced cellular damage was studied. Specifically, the ability of the new molecules to protect cultured cells from H(2)O(2)-induced DNA damage was evaluated using single cell gel electrophoresis (comet assay), while the neuroprotective activity of the new compounds against oxidative
