Disclosed are: labeled NSAIDs compounds which can be produced within a short time, can be used suitably for a PET method, and enable the imaging of cyclooxygenase-2; and a process for producing the labeled NSAIDs compounds. Specifically disclosed are isotope-labeled 2-arylpropionic acid compounds, each of which is a compound represented by general formula (1) (wherein Ar represents an aryl group which may have a substituent; R1 represents anyone selected from 11CH3, CH218F and CF218F; and R2 represents a hydrogen atom, or an alkyl group which may have a branch, wherein a compound wherein Ar is a benzene ring, R1 is 11CH3, and R2 is a hydrogen atom is excluded), or a pharmaceutically acceptable salt, hydrate, solvate or prodrug thereof.
本发明公开了标记的非甾体抗炎药(NSAIDs)化合物,能够在短时间内生产,适用于PET方法,并能够成像环氧合酶-2;以及制备标记的NSAIDs化合物的方法。具体公开了同位素标记的2-芳基丙酸化合物,每个化合物都是由通式(1)表示的化合物(其中Ar代表可能具有取代基的芳基基团;R1代表从11CH3、CH218F和CF218F中选择的任何一个;而R2代表氢原子或可能具有支链的烷基基团,其中排除了Ar为苯环,R1为11CH3,R2为氢原子的化合物),或其药学上可接受的盐、水合物、溶剂合物或前药。
