摘要
目的采用超高效液相色谱-四级杆-飞行时间串联质谱(UPLC-QTOF-MS)整合分子网络技术对龙葵全草的化学成分进行快速分析与鉴定,利用网络药理学技术初步探究其治疗肺癌的作用机制。方法运用UPLC-QTOF-MS,分别在正负离子模式下进行质谱检测与分析,定性龙葵全草中化学成分。同时将二级质谱图转换格式后上传到GNPS网站构建分子网络,对其化学成分进行分析。综合2种方法的定性分析结果结合网络药理学和分子对接,分析龙葵治疗肺癌过程中起主要作用的靶点及通路。结果质谱分析和GNPS分别鉴定和匹配出41个和54个化合物,其中相交11个化合物,共鉴定出84个化合物。综合上述结果筛选出有效活性成分7个,对应不重复靶点298个,疾病靶点1294个,相交靶点66个,富集分析得到28条信号通路、20个生物学过程、16个细胞组分、17个分子功能。分子对接结果显示核心靶点与核心成分均有较强的亲和力。结论运用UPLC-QTOF-MS/MS整合分子网络技术可快速、全面、系统地分析鉴定龙葵全草中的化学成分;网络药理学及分子对接结果为龙葵临床用药和药理研究提供了科学依据。
OBJECTIVE To rapidly analyze and identify the chemical constituents of Solanum nigrum L.by integrating ultrahigh performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-QTOF-MS)and molecular network technology.To preliminarily explore the mechanism for the treatment of lung cancer by network pharmacology.METHODS UPLC-QTOF-MS was used to detect and analyze the chemical constituents of Solanum nigrum L.in positive and negative ion mode.Meanwhile,the format conversion of spectra was uploaded to GNPS website to build a molecular network and then analyze its chemical composition.In the light of qualitative results,the combination of the network pharmacology and molecular docking was employed to analyze the main targets and pathways of Solanum nigrum L.in the treatment of lung cancer.RESULTS There were 41 and 54 compounds identified and matched by UPLC-QTOF-MS and GNPS,respectively.Among them,11 compounds intersected.Finally,a total of 84 compounds were identified.As a result,7 active components were screened out,which were related to 298 non-repeating targets,1294 disease targets and 66 intersecting targets.There were 28 signaling pathways,20 biological processes,16 cell components and 17 molecular functions obtained by enrichment analysis.The molecular docking results showed that the core targets had strong affinity with the core components.CONCLUSION Integrating UPLC-QTOF-MS/MS and molecular network technology can be used to quickly,comprehensively and systematically analyze the chemical constituents in the whole plant of Solanum nigrum L..The results of network pharmacology and molecular docking provide the scientific basis for its clinical treatment and pharmacological study.
