The study aimed to establish a HPLC method and a two-dimensional liquid chromatography-quadrupole time-of-flight mass spectrometry (2D-LC-Q-TOF/MS) method for the determination of the related substances degradated by tryptophan in pediatric compound amino acid injection and the exploration of the degradation pathway of tryptophan. The HPLC method was carried out on a Waters Atlantis T3 C18 (250 mm × 4.6 mm, 5 μm) column by gradient elution using phosphate buffer solution-acetonitrile (990∶12) and phosphate buffer solution-acetonitrile (65∶35) as the mobile phases to separate tryptophan and the related substances degradated by tryptophan. The selected components were then trapped in switch valve tube lines respectively and delivered to the second-dimensional desalting and deacidification gradient elution which was performed with an Agilent ZORBAX Eclipse Plus C18 (50 mm × 3.0 mm, 1.8 μm) column using acetonitrile-water (95∶5) as the mobile phases. The positive ion mode of the electrospray ionization source was adopted, the parent ions were detected using MS scan mode and the fragment ions were detected using targeted MS/MS mode. The structure of the unknown impurities was figured out by mass spectrometry elucidation. The results showed that tryptophan and its related substances in pediatric compound amino acid injection can be adequately separated under the established analytical conditions. A new impurity produced by the interaction between tryptophan and antioxidant excipients such as sodium bisulfite or sodium metabisulfite was discovered for the first time. The method can provide reference for the quality control of this injection.

建立HPLC法和二维液相色谱-质谱联用法研究小儿复方氨基酸注射液中色氨酸降解产生的有关物质, 探讨色氨酸的降解途径。HPLC法采用Waters Atlantis T3 C18色谱柱(250 mm × 4.6 mm, 5 μm), 以磷酸盐缓冲液-乙腈(990∶12) 和磷酸盐缓冲液-乙腈(65∶35) 为流动相进行梯度洗脱, 实现样品中色氨酸及其各降解杂质的分离, 通过多次简单中心切割工作模式将目标杂质捕集送入下一级与质谱串联的色谱系统, 从而达到在线快速脱盐和脱酸的目的, 二维采用超高效液相色谱-四级杆飞行时间质谱(UPLC-QTOF), Agilent ZORBAX Eclipse Plus C18色谱柱(50 mm × 3.0 mm, 1.8 μm), 以乙腈-水(95∶5) 为流动相进行等度洗脱。在电喷雾离子源正离子扫描(ESI+) 模式下, 通过一级全扫描锁定母离子后, 进行目标触发式二级质谱扫描, 获取碎片离子信息, 对未知降解杂质进行定性研究, 初步确定杂质结构。结果显示, 建立的分析条件可以有效分离检测小儿复方氨基酸注射液中色氨酸降解产生的有关物质, 并首次发现色氨酸与抗氧剂辅料亚硫酸氢钠或焦亚硫酸钠发生相互作用产生的一个新杂质, 为该品种的质量控制提供参考依据。

建立HPLC法和二维液相色谱-质谱联用法研究小儿复方氨基酸注射液中色氨酸降解产生的有关物质, 探讨色氨酸的降解途径。HPLC法采用Waters Atlantis T3 C18色谱柱(250 mm × 4.6 mm, 5 μm), 以磷酸盐缓冲液-乙腈(990∶12) 和磷酸盐缓冲液-乙腈(65∶35) 为流动相进行梯度洗脱, 实现样品中色氨酸及其各降解杂质的分离, 通过多次简单中心切割工作模式将目标杂质捕集送入下一级与质谱串联的色谱系统, 从而达到在线快速脱盐和脱酸的目的, 二维采用超高效液相色谱-四级杆飞行时间质谱(UPLC-QTOF), Agilent ZORBAX Eclipse Plus C18色谱柱(50 mm × 3.0 mm, 1.8 μm), 以乙腈-水(95∶5) 为流动相进行等度洗脱。在电喷雾离子源正离子扫描(ESI+) 模式下, 通过一级全扫描锁定母离子后, 进行目标触发式二级质谱扫描, 获取碎片离子信息, 对未知降解杂质进行定性研究, 初步确定杂质结构。结果显示, 建立的分析条件可以有效分离检测小儿复方氨基酸注射液中色氨酸降解产生的有关物质, 并首次发现色氨酸与抗氧剂辅料亚硫酸氢钠或焦亚硫酸钠发生相互作用产生的一个新杂质, 为该品种的质量控制提供参考依据。

The study aimed to establish a HPLC method and a two-dimensional liquid chromatography-quadrupole time-of-flight mass spectrometry (2D-LC-Q-TOF/MS) method for the determination of the related substances degradated by tryptophan in pediatric compound amino acid injection and the exploration of the degradation pathway of tryptophan. The HPLC method was carried out on a Waters Atlantis T3 C18 (250 mm × 4.6 mm, 5 μm) column by gradient elution using phosphate buffer solution-acetonitrile (990∶12) and phosphate buffer solution-acetonitrile (65∶35) as the mobile phases to separate tryptophan and the related substances degradated by tryptophan. The selected components were then trapped in switch valve tube lines respectively and delivered to the second-dimensional desalting and deacidification gradient elution which was performed with an Agilent ZORBAX Eclipse Plus C18 (50 mm × 3.0 mm, 1.8 μm) column using acetonitrile-water (95∶5) as the mobile phases. The positive ion mode of the electrospray ionization source was adopted, the parent ions were detected using MS scan mode and the fragment ions were detected using targeted MS/MS mode. The structure of the unknown impurities was figured out by mass spectrometry elucidation. The results showed that tryptophan and its related substances in pediatric compound amino acid injection can be adequately separated under the established analytical conditions. A new impurity produced by the interaction between tryptophan and antioxidant excipients such as sodium bisulfite or sodium metabisulfite was discovered for the first time. The method can provide reference for the quality control of this injection.

小儿复方氨基酸注射液(18AA-Ⅰ、18AA-Ⅱ、19AA-Ⅰ) 是一种由多种氨基酸根据营养或治疗需要以适当比例配制而成, 与复方氨基酸注射液的区别在于降低了苯丙氨酸、甲硫氨酸、甘氨酸的用量, 增加半胱氨酸和组氨酸的用量, 以适应婴幼儿代谢的特点并满足小儿营养需要[1]。由于其中存在多种易氧化氨基酸[2], 处方中均加入了抗氧剂焦亚硫酸钠或亚硫酸氢钠作为制剂辅料。
小儿复方氨基酸注射液中各氨基酸成分大多只有末端吸收且极性较大, 采用HPLC法进行杂质谱研究, 由于成分多、分离困难、末端吸收干扰多, 因此需针对其中不稳定氨基酸单独建立适当的方法进行分析。已有文献报道在制剂生产过程中谷氨酸会高温降解为焦谷氨酸[3], 在制剂生产和储存过程中甲硫氨酸会氧化产生甲硫氨酸亚砜[4]。色氨酸化学结构中因存在吲哚环而易被氧化降解, 导致输液颜色变深, 含量下降[5], 因此有必要对色氨酸的有关物质进行研究控制, 保障儿童用药安全。
本研究试验期间查询欧洲药典(EP10.0)、英国药典(BP2020) 和美国药典(USP43) 均收载了色氨酸原料的有关物质检查方法, 经过比较, 本文参照EP10.0色氨酸原料有关物质检查方法[6], 进行色谱条件优化, 并对收集到的7家企业生产的135批小儿复方氨基酸注射液中色氨酸有关物质进行研究。二维液相色谱-高分辨质谱联用技术因不受流动相类型限制, 且具备强大的定性能力, 已被广泛应用于药物有关物质的鉴定研究[7, 8], 本研究即采用该技术手段进行分析, 发现了小儿复方氨基酸注射液中色氨酸的一个新杂质, 为该品种的质量控制提供参考依据。

1　方法学验证
1.1　专属性
专属性结果表明, 溶剂及空白阴性原辅料不影响色氨酸有关物质的测定, 且色氨酸各已知杂质色谱峰与周围化合物色谱峰均能达到基线分离, 其中EP杂质B色谱峰1受到空白阴性原辅料峰的干扰, 因此EP杂质B色谱峰以峰2计, 色谱图见图1。
强制降解实验结果表明, 色氨酸原料在各降解条件下产生的主要降解产物为EP杂质B、EP杂质D、EP杂质C、EP杂质G; 色氨酸在氧化和光照条件下稳定性较差, 在高温条件下略不稳定, 在强酸、强碱条件下较稳定。降解产生的各杂质之间、杂质与主成分之间、杂质与阴性原辅料之间均能达到基线分离。强制降解实验前后供试品溶液中主峰面积和各杂质峰峰面积总和在95%~103%之间, 物料基本守恒。
1.2　未知杂质结构确证
供试品溶液中均检出了杂质S, 且该杂质的质量相对较高, 但在色氨酸原料强制降解供试品溶液中均未检出杂质S, 照二维液相色谱条件和质谱条件实验, 对杂质S进行定性分析。测得其[M+H]+的准确离子质量m/z 285.053 5, [2M+H]+的准确离子质量m/z 569.097 8, 见图2。经软件检索, 该质量数匹配度最高的分子式为C11H12N2O5S, 得分为95.55。以m/z 285.053 5作为母离子, 做子离子扫描, 得到主要特征碎片离子m/z 205.096 5、188.070 2、146.060 0、118.064 8, 见图3。推断杂质S为色氨酸和抗氧剂(亚硫酸氢钠或焦亚硫酸钠)反应产生的新杂质(2-亚硫酸氢色氨酸), 推测其质谱裂解规律见图4。
按处方比例配制色氨酸原料与辅料(亚硫酸氢钠或焦亚硫酸钠) 的样品溶液, 分别在高温、强光条件下开展强制降解实验。结果显示, 两种条件下均产生大量杂质S, 且强光条件下杂质S的生成量远高于高温条件, 进一步证实杂质S是色氨酸与亚硫酸氢钠或焦亚硫酸钠反应生成的降解杂质。H厂家根据这一反应制备纯化出了杂质S对照品, 并进行了结构确证, 1H NMR (400 MHz, CD3OD) δ 3.545~3.601 (dd, 1H), 3.677~3.727 (dd, 1H), 4.220~4.250 (m, 1H), 7.055~7.092 (m, 1H), 7.181~7.219 (m, 1H), 7.396~7.416 (d, 1H), 7.594~7.614 (d, 1H)。该对照品用于本研究的开展, 其保留时间和质谱信息均与样品中杂质S的结果一致。
1.3　线性范围、检测限和定量限
色氨酸和各已知杂质的线性范围、线性回归方程、相关系数、检测限和定量限见表1。结果表明, 色氨酸和各已知杂质在线性浓度范围内线性关系良好, 方法的灵敏度能够满足色氨酸有关物质的检测要求。
1.4　精密度
精密量取对照品溶液20 μL, 连续进样6次, 记录色谱图, EP杂质B、EP杂质D、EP杂质C、EP杂质G、杂质S、色氨酸和USP杂质B色谱峰面积RSD (n = 6) 分别为0.21%、0.12%、0.23%、0.67%、0.14%、0.20%、0.28%, 保留时间RSD (n = 6) 分别为0.11%、0.17%、0.14%、0.19%、0.04%、0.11%、0.01%, 表明仪器精密度良好。
1.5　重复性
制备小儿复方氨基酸注射液(19AA-Ⅰ, 批号: K1701031) 供试品溶液6份, 照HPLC法色谱条件实验, 采用杂质对照品外标法计算已知杂质量, 采用不加校正因子的主成分外标法计算未知杂质量, 样品中EP杂质D和USP杂质B均未检出, EP杂质B、EP杂质C、EP杂质G、杂质S、未知最大单个杂质和总杂质的平均含量分别为0.017%、0.124%、0.111%、0.352%、0.036%和0.703%, RSD分别为4.1%、4.8%、2.9%、3.9%、4.3%和3.6% (n = 6)。
1.6　准确度
照HPLC法色谱条件实验, 以标准曲线法测定并计算回收率, EP杂质B、EP杂质D、EP杂质C、EP杂质G、杂质S、色氨酸、USP杂质B的平均回收率分别为101.0%、98.3%、99.6%、93.1%、98.9%、98.0%和97.5%, RSD分别为1.0%、0.5%、0.8%、1.5%、0.4%、0.5%和0.5% (n = 9)。
1.7　稳定性
对照品溶液在自动进样器(设置温度15 ℃) 中, 12 h进样结果显示, EP杂质B、EP杂质D、EP杂质C、EP杂质G、杂质S、色氨酸、USP杂质B峰面积的RSD值分别为1.5%、1.7%、1.3%、1.7%、0.8%、1.5%和1.1%。供试品溶液在自动进样器(设置温度15 ℃) 中, 5 h进样结果显示, 样品中EP杂质D和USP杂质B均未检出, EP杂质B、EP杂质C、EP杂质G、杂质S、未知最大单个杂质峰面积的RSD值分别为0.8%、3.6%、4.8%、0.3%和1.9%。结果表明, 对照品溶液在自动进样器中放置12 h稳定, 供试品溶液在自动进样器中放置5 h稳定。
1.8　耐用性
耐用性试验结果表明, 更换色谱柱及流速和柱温发生微小变化时, 除保留时间稍有变化外, 各杂质出峰顺序不变, 各杂质色谱峰与周围化合物色谱峰均能达到基线分离, 检出杂质个数、杂质量均未发生明显变化, 方法的耐用性良好。
2　样品测定
对收集到的7个厂家共135批样品[其中小儿复方氨基酸注射液(18AA-Ⅰ) 来源于L、J、T、C厂家共计83批, 小儿复方氨基酸注射液(18AA-Ⅱ) 来源于S厂家共计8批, 小儿复方氨基酸注射液(19AA-Ⅰ) 来源于Q、H厂家共计44批] 进行了有关物质检查。参照注册标准YBH01482017有关物质项下色氨酸杂质总量的限度值2.0%, 结合样品测定结果, 确定该品种杂质S不得过1.2%, 其他单个杂质不得过1.0%, 杂质总量不得过2.0%。结果样品中均未检出EP杂质D和USP杂质B, 有6批样品不符合规定, 合格率95.6%, 见图5。
结果显示, 厂家C生产的100 mL玻璃输液瓶包装小儿复方氨基酸注射液(18AA-Ⅰ) 中色氨酸杂质量较高, 且显著高于该厂家20 mL安瓿瓶包装的同类产品。此外, 厂家C的100 mL规格产品与厂家S的产品在不同批次间的色氨酸杂质量均存在较大差异, 提示相关产品的生产工艺关键参数控制存在一定的不稳定性。
讨论
收起
本研究开发了一种2D-LC-Q-TOF/MS分析方法, 对小儿复方氨基酸注射液(18AA-Ⅰ、18AA-Ⅱ、19AA-Ⅰ) 中色氨酸降解产生的有关物质进行定性分析, 并首次鉴定出色氨酸与抗氧剂辅料亚硫酸氢钠或焦亚硫酸钠发生相互作用产生的一个新杂质, 本研究中命名为杂质S。亚硫酸氢钠或焦亚硫酸钠在光或热的作用下发生反应生成亚硫酸氢自由基, 而色氨酸是一种含有吲哚环结构的氨基酸, 亲电取代先发生在富π电子的吡咯环上, 优先发生的位置在3位, 当吲哚环的3位被占据时, 取代就发生在2位, 当这两个位置都被占据时, 取代才发生在苯环上[9-13]。因此亚硫酸氢自由基进攻色氨酸吲哚环结构的2位, 发生取代反应生成2-亚硫酸氢色氨酸。
亚硫酸氢钠和焦亚硫酸钠作为抗氧剂, 在本产品中应该起到抑制色氨酸氧化降解的作用, 但已有研究表明EP杂质B和EP杂质C的量会随着焦亚硫酸钠含量的增加而明显升高[14], 且在本研究中发现上述抗氧剂会和主成分色氨酸发生反应产生新的杂质, 因此需要考虑上述抗氧剂在本产品中添加的必要性, 进一步优化生产工艺, 提高产品质量。
本研究中发现安瓿包装的样品总体杂质量较低, 批内杂质分布较均匀; 充氮密封性好的输液瓶包装样品比未充氮的输液瓶包装样品中杂质量低, 杂质分布较均匀。厂家C的100 mL规格产品和厂家Q的产品均为玻璃输液瓶包装, 且仅抽真空, 没充氮, 杂质量较高。厂家S的产品杂质量和生产后流通时间长短呈显著正相关, 批内均匀性较差, 推测是瓶内有残余氧, 每瓶残氧量不同, 又无独立外包装, 没有遮光处理, 导致各瓶杂质量差异大; 且玻璃输液瓶内不断会有空气进入进行气体交换, 导致流通时间长的样品杂质量较高。若本产品采用玻璃输液瓶包装, 建议抽真空充氮, 保持瓶内微正压的状态, 并加独立外包装避光, 加强密封性控制, 可以有效抑制杂质的产生, 保证产品质量。
