In an effort to develop a new SPECT imaging agent for the translocator protein (TSPO), a series of novel iodinated quinoline-2-carboxamides have been synthesised and evaluated for binding affinity using rat brain homogenates. The outcome of the biological testing in combination with HPLC determination of the physicochemical properties of these compounds directed the design of new analogues resulting in 4-(2-iodophenyl)quinoline-2-N-diethylcarboxamide, a new TSPO ligand with higher affinity than the widely used clinical imaging agent PK11195.
为了开发一种新的用于转运蛋白(TSPO)的SPECT成像剂,合成了一系列新型碘化喹啉-2-羧酰胺,并使用大鼠脑匀浆对其结合亲和力进行了评估。生物测试结果结合高效液相色谱(HPLC)对这些化合物的物理化学性质的测定,指导了新类药物的设计,最终得到4-(2-碘苯基)喹啉-2-N-二乙基羧酰胺,这是一种新的TSPO配体,其亲和力高于广泛使用的临床成像剂PK11195。
