制备方法与用途

用途

Labelled Estradiol是一种在人体乳腺癌细胞组织培养中具有生物活性的雌激素，通常称为α-Estradiol或17 α-Estradiol。虽然17-α-Estradiol及其选择性受体ER-X并不属于经典的激素/受体内分泌系统，而是涉及发育和成年大脑中的重要自分泌/旁分泌功能。17- Estradiol可能对更年期的激素替代疗法以及治疗阿尔茨海默病和缺血性中风等神经退行性疾病具有巨大的潜在意义。

  Assay of labile estrogen o-quinones, potent carcinogenic molecular species, by high performance liquid chromatography–electrospray ionization tandem mass spectrometry with phenazine derivatization

  摘要：

  A sensitive and selective assay method for labile estrogen o-quinones, estrone (E-1)-2,3-quinone (Q), E-1-3,4-Q, estrachol (E-2)-2,3-Q and E-2-3,4-Q based on the use of phenazine (Phz) derivatization with o-phenylenediamine and high performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS) was described The Phz derivatives of four estrogen o-quinones were purified by solid phase extraction and analyzed by HPLC-ESI-MS/MS The protonated molecule was observed as a base peak for all Phz derivatives in their ESI-mass spectra (positive mode) In multiple reaction monitoring, the transition from [M+H](+) to m/z 231 was chosen for quantification Calibration curves for the o-quinones were obtained using standard catechol estrogens after sodium metaperiodate treatment and Phz derivatization Using this method, these four estrogen o-quinones were analyzed with the limit of quantification of 5 ng/ml in acetonitrile (MeCN)-blank matrix (1 4, v/v), respectively, on a basis of the weight of catechol estrogens Assay accuracy and precision for four estrogen o-quinones were 896-113 0% and 3 1-12.6% (5, 125 and 2000 ng/ml in MeCN-blank matrix) Applications of this method enabled to determine the catalytic activities on hydroxylation and subsequent oxidation of E-1 and E2 of Mushroom tyrosinase and rat liver microsomal fraction It was confirmed by this method that tyrosinase exhibited 2- and 4-hydroxylation and further oxidation activities for catechols in the ring-A of estrogens. Whereas rat liver microsomal fraction possessed only 2- and 4-hydroxylation activities, and further oxidation activity for catechol estrogens was low (C) 2010 Elsevier Ltd All rights reserved.

  practices in cattle in the European Union has become challenging since endogenous compounds such as estradiol derivatives can potentially be used as growth promoters. Due to the great difficulty in establishing a reference threshold value for endogenous steroids, the direct detection of steroid esters in hair is an efficient strategy for the detection of 'natural' steroid abuse in cattle. METHODS The

  理由：由于雌激素衍生物等内源性化合物有可能被用作生长促进剂，因此在欧盟，控制牛的同化代谢行为已成为一项挑战。由于很难为内源性类固醇建立参考阈值，因此直接检测头发中的类固醇酯是检测牛中“天然”类固醇滥用的有效策略。方法本研究旨在根据当前的欧洲标准开发和验证一种特定的液相色谱/串联质谱（LC / MS / MS）分析策略，以监测牛毛中的雌激素酯。丹磺酰化后通过阳离子电喷雾电离（ESI +）进行分析。然后评估了两种采集模式：单反应监测和前体离子扫描。结果结果表明，采用丹磺酰化步骤可大大提高LC /（ESI +）-MS / MS检测雌二醇17-酯的灵敏度。优化后，CCα值在1-10 ng g（-1）范围内，但癸酸酯化的癸酸酯除外，因为衍生化效率不高。此外，这种LC / MS / MS方法可以进行前体离子扫描，以筛选头发样品中这些雌二醇17-酯的存在。结论基于特定的产物离子，即天然条件下的m / z
