中文摘要
尽管α-硫辛酸具有很强的抗氧化和抗炎活性,但由于其不溶于水,其应用受到限制。采用~(31)P-核磁共振波谱法研究了一种新开发的α-硫辛酸水溶性衍生物的神经保护作用。高能量磷酸盐,ATP和磷酸肌酸(在活细胞中ATP的能量缓冲)的恢复,显着较高时,脑切片灌流水溶性α-硫辛酸。电子自旋共振光谱表明水溶性α-硫辛酸具有广泛的自由基清除活性。
英文摘要
Despite its strong antioxidative and anti-inflammatory activity, application of alpha-lipoic acid has been limited due to its water-insolubility. The neuroprotective effect of a newly-developed water-soluble derivative of alpha-lipoic acid was studied using 31P-nuclear magnetic resonance spectroscopy. The recovery of high-energy phosphates, ATP and phosphocreatine (energetic buffer of ATP in living cells), was significantly higher when brain slices were superfused with water-soluble alpha-lipoic acid. The electron spin resonance spectroscopy indicated a wide range of free radical scavenging activity of the water-soluble alpha-lipoic acid.
