1抗代谢类抗肿瘤药物对人肿瘤细胞中核苷酸代谢的影响显示文摘目的研究抗代谢类抗肿瘤药物对人肿瘤细胞核苷酸代谢的影响。方法采用离子对高效液相色谱法测定药物作用前后12种人肿瘤细胞中的12种核苷酸组分的含量,通过对主成分分析并结合单因素方差分析及受试者工作曲线分析、寻找与药物作用相关的标记物。结果对照组与加药组之间核苷酸代谢模式存在差异,筛选出贡献较大的组分为ATP、ADP、GMP和UDP,结合ROC曲线分析可知ATP、GMP和UDP具有一定的诊断准确性。结论 ATP、UDP和GMP为药物作用相关的最佳生物标记物。王迪 魏岚 刘希 刘昊昆 胡文艺 孙立新 2015西北药学杂志2015,30,1:6
2Effects of antibiotic antitumor drugs on nucleotide levels in cultured tumor cells:an exploratory method to distinguish the mechanisms of antitumor drug action based on targeted metabolomics显示文摘Nucleotide pools in mammalian cells change due to the influence of antitumor drugs,which may help in evaluating the drug effect and understanding the mechanism of drug action.In this study,an ion-pair RP-HPLC method was used for a simple,sensitive and simultaneous determination of the levels of 12 nucleotides in mammalian cells treated with antibiotic antitumor drugs(daunorubicin,epirubicin and dactinomycin D).Through the use of this targeted metabolomics approach to find potential biomarkers,UTP and ATP were verified to be the most appropriate biomarkers.Moreover,a holistic statistical approach was put forward to develop a model which could distinguish 4 categories of drugs with different mechanisms of action.This model can be further validated by evaluating drugs with different mechanismsof action.This targeted metabolomics study may provide a novel approach to predict the mechanism of action of antitumor drugs.Fang Wang Xi Liu Cuichai Liu Zheng Liu Lixin Sun 2015Acta Pharmaceutica Sinica B2015,5,3:0
