一种西格列汀中亚硝胺类杂质的制备方法
一种西格列汀中亚硝胺类杂质的制备方法亚硝胺类化合物是一类化学结构特殊的有机化合物，其中的亚硝基
（-NO）与氨基（-NH2）结合形成。
一些亚硝胺类化合物被认为是毒性物质，例如二甲基亚硝胺（DMA），三甲基亚硝胺（TMA）等。
因此，制备亚
硝胺类杂质的方法被广泛应用于食品、水、土壤等领域的污染控制和分析
检测。
以下是一种制备亚硝胺类杂质（以DMA为例）的方法：
1.材料准备：亚硝胺类前体化合物（例如亚硝酸盐）、还原剂（例如
亚硫酸钠）、溶剂（例如水或有机溶剂）。
2.反应体系：在适当的反应容器中，将亚硝酸盐和还原剂加入溶剂中，控制温度和pH值。
3.反应控制：通过控制温度和pH值，控制亚硝酸盐与还原剂的反应
速率。
一般来说，较低的温度和较高的pH值有利于亚硝胺类杂质的生成。
4.反应过程：在反应体系中，亚硝酸盐和还原剂发生还原反应，生成
亚硝胺类化合物。
反应过程中，可以使用适当的分析方法（例如HPLC、
GC-MS等）监测亚硝胺类化合物的生成情况。
5.杂质分离和纯化：通过适当的分离和纯化方法，将亚硝胺类化合物
从反应体系中分离提取出来，并去除其他杂质。
需要注意的是，亚硝胺类化合物具有一定的稳定性，因此在制备中需
要小心操作，避免其它杂质的产生。
同时，亚硝胺类杂质具有一定的毒性，对于实验室和工业环境中的人员需采取相应的安全措施进行防护。
通过以上的步骤，可以制备亚硝胺类杂质，为其在环境污染和食品安全领域的控制及分析提供了技术支持。
同时，也可以通过相关的研究深入了解亚硝胺类化合物的生成机理及其对环境和人体的危害。

氨基聚乙二醇-1,2-二硬脂酰甘油磷酰乙醇胺的合成
氨基聚乙二醇-1,2-二硬脂酰甘油磷酰乙醇胺的合成脂质体是一种定向药物载体，属于靶向给药系统的一种新剂型。
脂质体对机体毒副作用小，其脂质双分子层与生物膜有较大的相似性与组织相溶性，易于被组织吸收。
脂质体包裹药物为物理过程，不改变药物分子结构，当药物被包裹后可降低药物毒性，减小药物使用量，具有缓释和控释作用，因此，脂质体靶向给药可以大大提高药物的疗效[1, 2]。
甲氧基聚乙二醇-1, 2-二硬脂酰甘油磷酰乙醇胺 (mPEG-DSPE) 是制备脂质体的重要辅料之一，它一端是甲氧基聚乙二醇(mPEG)，具有亲水性，另一端是脂肪酸甘油酯，具有亲脂性。
不同于天然磷脂，mPEG-DSPE属于合成磷脂，具有确定的化学成分。
经过mPEG修饰后脂质体的柔顺性和亲水性显著增强，通过单核巨噬细胞系统吞噬，减少脂质体脂膜与血浆蛋白的相互作用，延长循环时间，形成了长循环脂质体[3, 4]。
将抗体或配体结合在mPEG的末端，既可保持长循环，又可保持对靶体的识别[5, 6]。
mPEG-DSPE在脂质体研究方面应用极为广泛，国内外需求量在逐年增加，此类产品市售价格昂贵，所以，开发新的mPEG-DSPE合成方法有着广阔的市场前景。
虽然国内外对mPEG-DSPE 的应用研究已较为深入，但其合成方法报道的较少。
有文献[7]报道通过mPEG与三光气反应进行制备，但该路线步骤多，三光气毒性较大，反应收率较低，给以后的放大生产带来不便。
本文探究了一种新的合成方法，以1, 2-二硬脂酸甘油酯为原料，将其与三氯氧磷及乙醇胺反应，合成关键中间体1, 2-二硬脂酰甘油磷酰乙醇胺 (DSPE) 后，再与mPEG2000反应，制备mPEG2000-DSPE (图式1)。
该方法具有操作简单、收率高、三废少等优点，有较好的应用前景。

LCMS检测西他沙星原料中基因毒性杂质的含量
LC-MS检测西他沙星原料中基因毒性杂质的含量石莹1宋雪洁3李浩冬2路显锋2*1药物研究院分析所，扬子江药业集团，泰州2253212药物制剂新技术国家重点实验室，扬子江药业集团，泰州2253213质量管理部，扬子江药业集团，泰州225321摘要建立了LC-MS 法测定西他沙星中基因毒性杂质对甲苯磺酸甲酯和对甲苯磺酸乙酯含量的方法。
方法:采用Agilent Poroshell 120 EC-C18色谱柱；流动相为纯水（0.1%甲酸）:甲醇（V/V）=60:40；稀释剂为乙腈（0.1%甲酸）:纯水（V/V）=50:10；柱温为40℃；进样体积为5µl；流速为0.4ml/min；采用正离子模式进行扫描。
对甲苯磺酸甲酯测定浓度在0.76ng/ml~15.27ng/ml范围内，线性关系良好；对甲苯磺酸乙酯测定浓度在0.75ng/ml~15.01ng/ml范围内，线性关系良好。
对甲苯磺酸甲酯的定量限为0.0038ng；对甲苯磺酸乙酯的定量限为0.0038ng。
杂质回收率在限度浓度80%、100%和160%三个浓度水平均在90~110%之间，该方法准确度良好。
该方法适用于西他沙星原料中对甲苯磺酸甲酯和对甲苯磺酸乙酯的检测。
西他沙星(sitafloxacin)是日本第一制药有限公司继左氧氟沙星后开发出的一种强力广谱新氟喹诺酮类抗菌剂，该药对革兰氏阳性球菌，革兰氏阴性菌以及厌氧菌的抗菌活性是左氧氟沙星的4～32倍，同时对肺炎球菌DNA 促旋酶和拓扑同功酶有双重抑制作用。
临床表现有极广的抗菌谱，特别是对呼吸道的病菌有极强的抗菌活性。
因西他沙星的一个起始物料为对甲苯磺酸盐，在后续反应中对甲苯磺酸若有残留，可能会与溶剂甲醇、乙醇反应生成具有基因毒性的杂质—对甲苯磺酸甲酯和对甲苯磺酸乙酯，故采用LC-MS法对产品中的对甲苯磺酸甲酯/乙酯进行控制。

mgtfsi2质谱
mgtfsi2质谱
MgTFSI2（镁双（三氟甲基磺酰）亚胺）是一种镁盐，通常用于电解质溶液，特别是在镁离子电池中。
在质谱（Mass Spectrometry, MS）分析中，MgTFSI2的分子量和分子结构可以被用来确定其质谱特征。
MgTFSI2的分子式为Mg(CF3SO2)2，分子量为322.4 g/mol。
在质谱图中，MgTFSI2会产生特定的质谱峰，其峰值通常对应于分子离子（MgTFSI2+）的质荷比（m/z）。
由于MgTFSI2含有镁（Mg）和氟（F）等元素，其质谱图会有相应的特征峰，这些峰可以用来识别和定量MgTFSI2。
在质谱分析中，MgTFSI2的样品通常需要通过电离源（如电子喷雾电离源）进行电离，使其分子转化为离子形式。
然后，这些离子会在质量分析器（如四级杆质量分析器）中根据它们的质荷比进行分离，最终通过检测器（如离子计数检测器）记录下来。
由于MgTFSI2的化学性质，其在质谱分析中的电离可能主要发生在其R组（CF3SO2）上，而不是镁离子（Mg2+）上。
因此，质谱图可能会显示出R组+1的电离产物，以及可能的碎片离子。
在实际应用中，通过对MgTFSI2标准样品的质谱分析，可以建立其质谱指纹，用于后续样品的识别和分析。
这有助于在镁离子电池和其他电化学应用中准确地表征和量化MgTFSI2。
