The aim of our study was to synthesize new radiotracers for in vivo imaging to examine the metabolic fate of fatty acids according to their unsaturation degree. Three different fatty acids of the 18-carbon series have been synthesized, labeled with 123I, and their biodistribution has been evaluated in mice in vivo. The main result shows a different distribution pattern of the fatty acids according to their degree of unsaturation between the white adipose tissue and the muscles, which is coherent with previous studies using stable isotopes.
我们研究的目的是合成用于体内成像的新型放射性痕量物质,以根据
脂肪酸的不饱和程度研究其代谢命运。我们合成了三种不同的 18 碳
脂肪酸,用 123I 标记,并在小鼠体内对它们的
生物分布进行了评估。主要结果显示,根据
脂肪酸的不饱和程度,它们在白色脂肪组织和肌肉之间的分布模式有所不同,这与之前使用稳定同位素进行的研究结果一致。
