          摘  要  核酸类药物的生物分析方法主要有基于配体结合分析、基于聚合酶链反应和基于液相色谱分离技术3大类,前两者灵敏
          度虽高,但选择性较差,很难区分寡核苷酸本身及其较短的代谢产物。基于液相色谱分离技术生物分析方法的灵敏度虽略有逊
          色,但由于其具有高选择性,能够区分寡核苷酸本身及其代谢产物,故在核酸类药物的临床前和临床研究中展现出了广阔的应用
          前景。本文综述了该类方法中的高效液相色谱-紫外检测(HPLC-UV)法、高效液相色谱-荧光(HPLC-FL)法、液相色谱-串联质谱
         (LC-MS/MS)法、液相色谱-高分辨质谱法、微流液相色谱-串联质谱(microflow LC-MS/MS)法、杂交液相色谱-串联质谱法的特点
          及其在核酸类药物分析中的应用情况,发现除HPLC-UV法的检测灵敏度较低以外,其余方法均具有较高的灵敏度,但尚存在一些
          不足,如HPLC-FL法需要设计合适的探针、LC-MS/MS法需要标准物质、microflow LC-MS/MS法成本较高等。另外,一些相关策
          略及技术(如非特异性吸附解决策略、样品前处理技术等)的发展,在提高方法灵敏度的同时,也进一步加速了基于液相色谱分离
          技术的核酸类药物生物分析方法的发展。

          ABSTRACT   There  are  three  types  of  bioanalytical  methods  for  nucleic  acid  drugs,  including  ligand  binding  assay,  quantitative
          polymerase  chain  reaction  and  liquid  chromatography-based  bioanalytical  technologies.  Although  the  first  two  assays  have  high
          sensitivity,  they  have  poor  selectivity  and  can  not  differentiate  between  intact  and  truncated  metabolites.  Liquid  chromatography-
          based  bioanalytical  technologies  which  are  less  sensitive,  offer  high  selectivity  for  the  identification  of  intact  and  truncated
          metabolites.  They  have  broad  application  prospects  in  both  preclinical  and  clinical  investigations  of  therapeutic  nucleic  acid  drugs.
          This paper provides a critical review on the characteristics of these technologies and their application to analyze nucleic acid drugs,
          including  high  performance  liquid  chromatography-ultraviolet  detection (HPLC-UV),  high  performance  liquid  chromatography-
          fluorescence (HPLC-FL), liquid chromatography-tandem mass spectrometry (LC-MS/MS), liquid chromatography-high resolution-
          mass  spectrometry,  microflow  liquid  chromatography-tandem  mass  spectrometry (microflow  LC-MS/MS)  and  hybridization  liquid
          chromatography-tandem mass spectrometry. Although these technologies have high sensitivity except for HPLC-UV, they still have
          some  shortcomings,  such  as  suitable  probes  need  to  be  designed  for  HPLC-FL,  standard  substance  for  LC-MS/MS,  and  high  cost
          for  microflow  LC-MS/MS.  In  addition,  the  development  of  some  related  strategies  or  technologies (e.g.  non-specific  adsorption
          strategy,  sample  pretreatment)  which  can  improve  the  sensitivity,  has  hastened  the  development  of  liquid  chromatography-based
          bioanalytical technologies for nucleic acid drugs.
