Accelerator Mass Spectrometry is an established technology whose essentiality extends beyond simply a better detector for radiolabeled molecules. Attomole sensitivity reduces radioisotope exposures in clinical subjects to the point that no population need be excluded from clinical study. Insights in human physiochemistry are enabled by the quantitative recovery of simplified AMS processes that provide biological concentrations of all labeled metabolites and total compound related material at non-saturating levels. In this paper, we review some of the exploratory applications of AMS (14)C in toxicological, nutritional, and pharmacological research. This body of research addresses the human physiochemistry of important compounds in their own right, but also serves as examples of the analytical methods and clinical practices that are available for studying low dose physiochemistry of candidate therapeutic compounds, helping to broaden the knowledge base of AMS application in pharmaceutical research.
加速器质谱分析是一项成熟的技术，其重要性不仅在于它是放射性标记分子的更好探测器。阿特摩尔灵敏度将临床研究对象中的放射性同位素暴露降低到无需排除任何人群参与临床研究的程度。通过定量回收简化的 AMS 过程，实现了人类生理化学的深入了解，该过程以非饱和水平提供所有标记代谢物和总相关化合物材料的生物浓度。在本文中，我们回顾了 AMS(14)C 在毒理学、营养学和药理学研究中的一些探索性应用。这些研究本身涉及到重要化合物的人体生理学化学，但也为研究候选治疗化合物低剂量生理学化学的分析方法和临床实践提供了范例，有助于拓宽 AMS 在药物研究中的应用知识库。
