在SmartMass平台上使用串联质谱数据进行兽药的非靶标筛选。这一新开发的软件使用特征裂解模式(CFP)来识别化学品,特别是那些含有特定亚结构的化学品。采用超高效液相色谱法(UPLC)对17种磺胺类药物进行分离,并采用SmartMass对Orbitrap质谱仪上获得的串联质谱(MS/MS)数据进行处理。数据自动提取,并识别和分析与预先建立的分析规则,每一个磺胺。通过使用该软件,超过98%的错误候选结构被消除,并且所有正确的结构都在排名列表的前10名中找到。此外,SmartMass还可以用于通过简单的预先构建的规则识别稍微修改的违禁药物和代谢物。
Non-target screening of veterinary drugs using tandem mass spectrometric data was performed on the SmartMass platform. This newly developed software uses the characteristic fragmentation patterns (CFP) to identify chemicals, especially those containing particular substructures. A mixture of 17 sulfonamides was separated by ultra performance liquid chromatography (UPLC), and SmartMass was used to process the tandem mass spectrometry (MS/MS) data acquired on an Orbitrap mass spectrometer. The data were automatically extracted, and each sulfonamide was recognized and analyzed with a prebuilt analysis rule. By using this software, over 98 % of the false candidate structures were eliminated, and all the correct structures were found within the top 10 of the ranking lists. Furthermore, SmartMass could also be used to identify slightly modified contraband drugs and metabolites with simple prebuilt rules.
