    • PROBLEM TO BE SOLVED: To provide labeled derivatives for image diagnosis with which prompt and noninvasive classification can be performed between sensitive patients and insensitive patients to a survivin expression inhibitor, particularly YM155.SOLUTION: The present inventors conducted intensive studies about a method of performing classification between sensitive patients and insensitive patients to YM155 and has found that 1-(2-methoxyethyl)-2-methyl-4,9-dioxo-3-(pyrazin-2-ylmethyl)-4,9-dihydro-1H-naphtho[2,3-d]imidazol-3-ium or labeled derivatives of a salt thereof has good accumulation to a YM155-sensitive tumor and enables the tumor to be imaged by positron emission tomography (PET) or single photon emission computed tomography (SPECT). Thus, the labeled derivatives of the present invention can be used as a radio-labelled tracer for the prompt and noninvasive classification between the sensitive patients and the insensitive patients to YM155, diagnosis of size and staging of the YM155-sensitive tumor, and diagnosis for a therapeutic effect by YM155 or other antitumor agents.
    • 要解决的问题:提供用于图像诊断的标记衍生物,其可以在敏感患者和不敏感患者之间进行快速和非侵入性分类至存活蛋白表达抑制剂,特别是YM155。解决方案:本发明人对进行分类的方法进行了深入研究 敏感患者和不敏感患者之间的YM155,发现1-(2-甲氧基乙基)-2-甲基-4,9-二氧代-3-(吡嗪-2-基甲基)-4,9-二氢-1H-萘并[ 2,3-d]咪唑-3-酮或其盐的标记衍生物对YM155敏感的肿瘤具有良好的积累,并且能够通过正电子发射断层摄影(PET)或单光子发射计算机断层摄影(SPECT)对肿瘤进行成像, 。 因此,本发明的标记衍生物可以用作放射性标记的示踪剂,用于敏感患者和不敏感患者之间的YM155的快速和非侵入性分类,YM155敏感性肿瘤的大小和分期的诊断,以及诊断 YM155或其他抗肿瘤剂的治疗作用。
