their functional TRPV1 activity and radical-scavenger activity. The safe biological profile together with the protective effect against hypoxia damage as well as the in vitro antioxidant properties were also evaluated. Although less potent than capsaicin, almost all lipoic amides were found to be TRPV1 agonists and, specifically, compound 4, the lipoic analogue of capsaicin, proved to be the best ligand
α-硫辛酸是一种含硫营养素,具有多效性和安全的生物学特征,被选择用于替代辣椒素的不饱和烷基酸,目的是获得作为 TRPV1 配体具有潜在活性并具有显着抗氧化特性的硫辛酰胺。因此,通过简单的合成程序并测试了它们的功能性 TRPV1 活性和自由基清除剂活性,以良好的收率获得了九种化合物。还评估了安全的生物学特性以及对缺氧损伤的保护作用以及体外抗氧化特性。尽管不如辣椒素那么有效,但几乎所有的硫辛酰胺都被发现是 TRPV1 激动剂,特别是化合物4,辣椒素的硫辛类似物,被证明是功效和效力方面最好的配体。EPR 实验和体外生物学分析表明,受试化合物具有抗氧化应激的潜在保护作用及其安全的生物学特性。化合物4、5和9显着改善由缺氧条件引起的线粒体膜电位并降低 F2-异前列烷,已知的氧化应激标志物。因此,实验结果鼓励进一步研究这些硫辛酰胺的治疗潜力。
