    • A radioactive halogen-labeled phenyoxyaniline derivative represented by the following formula: wherein R1 represents a group such as an alkyl group; X1, X2, X3 and X4 represent each a hydrogen atom, an alkyl group, an alkoxy group, an alkoxy group carrying 11C introduced thereinto or a radioactive halogen atom, provided that at least one of X1, X2, X3 and X4 represents an alkoxy group carrying 11C introduced thereinto or a radioactive halogen atom; which is a compound useful as a PBR ligand having a high affinity and a high selectivity. In in vitro measurement of PBR, a PBR ligand having a high affinity and a high selectivity is labeled with a radioactive halogen nuclear species so as to enable the measurement of PBR in vivo with the use of means including not only PET but also SPECT. Thus, a compound which is useful in early diagnosing, preventing and treating diseases such as Alzheimer type dementia can be obtained.
    • 由下式表示的放射性卤素标记的苯氧基苯胺衍生物:其中R1表示烷基等基团; X 1,X 2,X 3和X 4各自表示氢原子,烷基,烷氧基,带有11C的烷氧基或放射性卤素原子,条件是X 1,X 2,X 3和X 4中的至少一个表示烷氧基 携带11C的基团或放射性卤素原子; 其是可用作具有高亲和力和高选择性的PBR配体的化合物。 在PBR的体外测量中,具有高亲和力和高选择性的PBR配体用放射性卤素核物种进行标记,以便能够使用不仅包括PET而且还包括SPECT的方法在体内测量PBR。 因此,可以获得可用于早期诊断,预防和治疗诸如阿尔茨海默氏型痴呆症的疾病的化合物。
