Innovate combination of sevoflurane dilution in dimethyl sulfoxide: A stability study by gas chromatography and nuclear magnetic resonance

World Journal of Pharmacology 2016年第3期5卷 59-67页

AIM To investigate physicochemical stability of sevoflurane in dimethyl sulfoxide using gas chromatography with a flame ionization detector and nuclear magnetic resonance(NMR).METHODS Undiluted sevoflurane, plus dilutions 1:2, 1:5, 1:10, 1:25, and 1:50 in dimethyl sulfoxide were prepared in a vertical laminar flow cabinet class Ⅱ type B and stored at different temperatures(23 ℃, 6 ℃, and-10 ℃) for 45 d. Sterile 1 mL polypropylene amber syringes to minimize light degradation, caps and needles were used. The presence of sevoflurane and its degradation products in the samples was determined by gas chromatography with flame ionization detector(260 ℃, 40 min), and by ~1H, ^(19) F, and proton-decoupled ^(19) F nuclear magnetic *** The gas chromatography analysis showed sevoflurane and dimethyl sulfoxide(DMSO) retention times were 2.7 and 13.0 min, respectively. Pure DMSO injection into the column resulted in two additional peaks at 2.1 and 2.8 min. The same sevoflurane peak at 2.7 min was observed in all the dilutions at-10 ℃, 4 ℃ and 25 ℃. The NMR spectra showed signals consistent with the sevoflurane structure in all the dilutions at-10 ℃, 4 ℃ and 25 ℃. In the ~1H spectrum, two signals corresponding to the sevoflurane molecule were observed at 5.12 and 4.16 parts per million(ppm5). In the ^(19)F-NMR spectrum, two signals were observed at-76.77 ppm and-157.13 ppm. In the ^(19)F NMR CPD, two signals were observed at-76.77 ppm and-157.13 ppm. The first one showed a doublet(JF-F = 3.1 Hz) which integrated by six fluorine nuclei from the hexafluoro-isopropyl group. The second signal was integrated by a fluorine atom and showed a septuplet(JF-F = 3.1 Hz).CONCLUSION This study shows that different concentrations of sevoflurane in dimethyl sulfoxide retain their chemical composition after exposure to different temperatures for a period of 45 d.

摘要在阿尔茨海默病(AD)中,在β-淀粉样蛋白斑块周围发现了反应性星形胶质细胞和营养不良的神经突(异常的突触前元件)。笔者的前期研究已经表明,反应性星形胶质细胞会包裹、吞噬和降解APP小鼠以及AD患者海马中营养不良的突触,但仅波及不到7%的营养不良神经突,这表明星形胶质细胞在AD中的吞噬能力降低。本研究旨在通过分析原代星形胶质细胞培养物对分离突触(突触神经小体,SNs)吞噬和降解的能力来深入了解其潜在机制。SNs分别来自APP(包含营养不良性突触和β淀粉样肽)小鼠、Tau(包含AT8-和AT100-阳性磷酸化Tau)小鼠以及WT(对照)小鼠。我们发现与SNs-WT相比,星形胶质细胞的吞噬和降解能力在SNs-APP大大降低,但在AT8/AT100阳性的SNs-Tau却没有。在12月大的APP小鼠的海马中证实了星形胶质细胞吞噬能力的降低,因为只有(1.60±3.81)%的斑块状星形胶质细胞具有吞噬结构。
