The present invention relates to novel modified fatty acid analogs, where a positron or gamma-emitting label is placed at a position on a fatty acid backbone and an organic substituent is substituted at the 2,3; 3,4; 4,5; 5,6 and other sequence positions of a fatty acid backbone. These novel fatty acid analogs are designed to enter the tissues of interest by the same long chain fatty acid carrier mechanism as natural fatty acids, however, functional substituents in the 2,3; 3,4; 4,5; 5,6 and other sequence positions, block the catabolic pathway, thus trapping these analogs in a virtually unmodified form in the tissues of interest.
本发明涉及一种新型的改性脂肪酸类似物,其中在脂肪酸骨架的一个位置放置正电子或伽马发射标签,并在脂肪酸骨架的2,3; 3,4; 4,5; 5,6和其他序列位置上替换有机取代基。这些新型脂肪酸类似物被设计为通过与天然脂肪酸相同的长链脂肪酸载体机制进入感兴趣的组织,但是,在2,3; 3,4; 4,5; 5,6和其他序列位置上的功能性取代基会阻止分解途径,从而在感兴趣的组织中将这些类似物困在几乎未经修改的形式中。
