    通过电荷反转衍生提高类二十烷酸的灵敏度质谱检测
    摘要:
    液相色谱-电喷雾电离-串联质谱联用 (LC-ESI-MS/MS) 是一种分析多不饱和脂肪酸(包括类二十烷酸)含氧代谢物的强大方法。这里我们描述了一种新的衍生化试剂N的合成-(4-氨基甲基苯基)吡啶鎓 (AMPP),可通过酰胺键以定量产率与类二十烷酸偶联。与未衍生化分析物的负模式电喷雾电离检测相比,将类二十烷酸的羧酸转化为阳离子 AMPP 酰胺可将检测灵敏度提高 10 到 20 倍。这种电荷反转衍生允许在电喷雾电离质谱仪中检测阳离子而不是阴离子,从而提高灵敏度。另一个因素是 AMPP 酰胺在分析物部分而不是仅在阳离子标签部分发生相当大的碰撞诱导解离,这使得同量异位衍生物可以通过串联质谱法进行区分,这进一步提高了灵敏度和特异性。这种简单的衍生方法允许前列腺素,2、白三烯B 4、羟基二十碳四烯酸异构体和花生四烯酸在复杂生物样品中定量,定量限在200-900 fg范围内。可以预期,AMPP 衍生化

  • High-performance liquid chromatography/thermospray mass spectrometry of some prostaglandins of the F series
    作者:J. Abián、E. Gelpí
    DOI:10.1002/jms.1190300412
    日期:1995.4
    Thermospray (TSP) mass spectra and chromatographic characteristics of the prostanoids PGF2α, 6-keto-PGF1α, 2,3-dinor-6-keto-PGF1α, and their methyl esters and methoximes are reported. The spectra of these compounds are dominated by ions of the type [M + H +xNH3 - nH2O]+ in the positive-ion mode and [M - H + xAcOH – nH2O]− in the negative-ion mode (n ranges from 0–4 and x is 0 or 1). The relative abundances of these ions depend on the particular structure, source and interface temperatures and eluent composition. In addition, these compounds show losses of 44 mass units, mainly due to the loss of the C-10–C-11 moiety, as demonstrated by deuterium labelling of PGF2α. Methoximated derivatives of 6-keto-PGF1α also show low-abundance ions due to fragmentation in the position α to the methoxime group. The liquid-phase equilibria of tautomers of 2,3-dinor-6-keto-PGF1α or products thereof which direct its particular chromatographic behavior, can be effectively blocked by methoximation of the keto group thus improving its detectability. Detection limits of 20 ng on-column may be obtained for this derivative. Adsorption and hydrolysis in the interface are the principal factors responsible for this relatively high detection limit.
    报告了前列腺素PGF2α、6-酮-PGF1α、2,3-二去氢-6-酮-PGF1α及其甲基酯和甲氧ime的热喷雾(TSP)质谱和色谱特性。这些化合物的质谱在正离子模式下以[ M + H + xNH3 - nH2O]+离子为主,在负离子模式下以[M - H + xAcOH - nH2O]−离子为主(n的范围为0-4,x为0或1)。这些离子的相对丰度取决于特定的结构、来源、界面温度和洗脱液成分。此外,这些化合物表现出44个质量单位的损失,主要是由于C-10-C-11部分的损失,这一点通过对PGF2α的氘标记得到了证实。6-酮-PGF1α的甲氧化衍生物也表现出低丰度的离子,主要是由于在甲氧ime基团的α位发生碎片化。2,3-二去氢-6-酮-PGF1α的互变异构体或其产物的液相平衡会影响其特定的色谱行为,而甲氧化酮基团的处理可以有效阻止这一现象,从而提高其可检测性。对于该衍生物,可以获得20 ng的柱上检测限。界面中的吸附和水解是导致这一相对高检测限的主要因素。

  • Effects of cyclodextrins on the hydrolysis of prostacyclin and its methyl ester in aqueous solution.
    作者:KANETO UEKAMA、FUMITOSHI HIRAYAMA、TORU WAKUDA、MASAKI OTAGIRI
    DOI:10.1248/cpb.29.213
    日期:——
    The rates of hydrolysis of prostacyclin (PGI2) and its methyl ester (PGI2Me) in aqueous solution were significantly retarded by α-, β-, and γ-cyclodextrins (α-, β-, and γ-CyDs), and showed characteristic saturation kinetics and competitive inhibition. The deceleration effects of CyDs on the hydrolysis of PGI2Me were about 3 times larger than those on the hydrolysis of PGI2. The importance of the spatial relationship between the host and guest molecules was reflected in the kinetically determined stability constant (Kc) for these inclusion complexations. To elucidate the deceleration mechanism of the CyDs, the effects of pH, solvent and temperature on the hydrolysis rate were studied. The protolytic dissociation of the terminal carboxylic acid moiety of PGI2 was suppressed by the binding to CyDs, depending upon the magnitude of the Kc value. Thermodynamic activation parameters suggested that the deceleration mechanism of CyDs in the case of PGI2 was somewhat different from that for PGI2Me, which may be due to different modes of inclusion.
    前列环素(PGI2)及其甲酯(PGI2Me)在水溶液中的水解速率受到α-、β-和γ-环糊精(α-、β-和γ-CyDs)的显著延缓,并表现出特征性的饱和动力学和竞争性抑制。CyDs 对 PGI2Me 水解的减速作用约为 PGI2 水解的 3 倍。这些包合物的动力学稳定常数(Kc)反映了主分子和客分子之间空间关系的重要性。为了阐明 CyDs 的减速机制,研究了 pH 值、溶剂和温度对水解速率的影响。PGI2 末端羧酸分子的原生解离受到与 CyDs 结合的抑制,这取决于 Kc 值的大小。热力学活化参数表明,CyDs 对 PGI2 的减速机制与对 PGI2Me 的减速机制有些不同,这可能是由不同的包含模式造成的。
