摘要

[1'-13 C]柠檬酸（1）由 1,3-丙酮二羧酸二甲酯通过两个步骤高效制备而成，可作为呼气测试的探针。之所以选择这种合成方法，是因为其产量高且具有可重复性。给大鼠口服化合物 1，成功地跟踪了大鼠呼气中 13 CO2 /12 CO2 比率（Δ13 CO2）增加的时间过程，表明了 1 的新陈代谢。

Preparation of [1′-13C]citric acid as a probe in a breath test to evaluate tricarboxylic acid cycle flux

[1′-¹³C]Citric acid (1) was efficiently prepared from dimethyl 1,3-acetonedicarboxylate in two steps as a probe for a breath test. The synthetic method was selected because of the yield and reproducibility. Compound 1 was orally administrated to rats, and the time course of the increase of ¹³CO₂/¹²CO₂ ratios (Δ¹³CO₂) in their breath was successfully followed, indicating the metabolism of 1. Thus, the ¹³C-breath test using 1 is a promising method to evaluate tricarboxylic acid (TCA) cycle flux.
