carbon-11 for evaluation with positron emission tomography (PET) in monkey. After intravenous injection, [11C]31 entered brain to give a high proportion of TSPO-specific binding. These findings augur well for the future application of [11C]31 in humans. Consequently, the binding of 31 to human TSPO was tested on samples of brain membranes from deceased subjects who through ethically approved in vitro
根据我们之前报道的药效团/拓扑模型设计的一系列新型N 1 -甲基-(2-苯基吲哚-3-基)乙醛酰胺19 - 31对 18 kDa 易位蛋白 (TSPO) 显示出高亲和力并铺平开发新的放射性标记探针的方法。因此,配体31,N,N-二-正-丙基-(N 1 -甲基-2-(4'-硝基苯基)吲哚-3-基)乙醛酰胺,具有亲和性和亲脂性的最佳组合,用碳- 11 用于在猴子中使用正电子发射断层扫描 (PET) 进行评估。静脉注射后,[ 11 C] 31进入大脑以提供高比例的 TSPO 特异性结合。这些发现预示着[ 11 C] 31未来在人类中的应用。因此,31与人类 TSPO的结合在来自已故受试者的脑膜样本上进行了测试,这些受试者之前通过伦理批准的体外研究被确定为高亲和力结合剂 (HABs)、混合亲和力结合剂 (MABs) 或低亲和力结合剂。 - 已知 TSPO 配体 PBR28 ( 2 ) 的亲和结合剂
