一種正子放射斷層造影追蹤劑,用以成像過度表現載脂蛋白型前列腺素D合成酶(Lipocalin-type prostaglandin D synthase, L-PGDS)之腫瘤或腦神經細胞之用途。本發明已製備使用可接受量放射性的氟18標定之氟丁基依他尼酰胺之穀胱甘肽綴合物 (glutathione conjugate of fluorine-18-labeled fluorobutyl ethacrynic amide),其可與載脂蛋白型前列腺素D合成酶(Lipocalin-type prostaglandin D synthase, L-PGDS)結合,並可用於體外和體內的成像研究。 A PET tracer for imaging tumors or neurological disorders that overexpress L-PGDS enzyme is provided. The present invention have prepared a glutathione conjugate of fluorine-18-labeled fluorobutyl ethacrynic amide using an acceptable amount of radioactivity that is capable of binding to L-PGDS and can be used forin vitroandin vivoimaging studies. |
