A series of novel 4-phenylquinazoline-2-carboxamides (1–58) were designed as aza-isosters of PK11195, the well-known 18 kDa translocator protein (TSPO) reference ligand, and synthesized by means of a very simple and efficient procedure. A number of these derivatives bind to the TSPO with Ki values in the nanomolar/subnanomolar range, show selectivity toward the central benzodiazepine receptor (BzR)
一系列新的4-苯基喹唑啉-2-羧酰胺(1 - 58)被设计为PK11195,公知的18 kDa的转运蛋白(TSPO)参考配体,的氮杂等排并合成由一个非常简单和有效的程序的装置。这些衍生物中的许多与TSPO结合的K i值在纳摩尔/亚纳摩尔范围内,对中央苯并二氮杂receptor受体(BzR)表现出选择性,并显示出结构亲和力关系,与先前公布的配体-TSPO相互作用的药效团/拓扑模型一致。
