The peripheral benzodiazepine receptor (PBR) is pharmacologically distinct from the central benzodiazepine receptor (CBR) and has been identified in a wide range of peripheral tissues as well as in the central nervous system. Although numerous studies have been performed of it, the physiological roles and functions of the PBR are still unclear. In the present study, in exploring new types of ligands
外周苯二氮卓类受体(PBR)在药理上不同于中枢苯二氮卓类受体(CBR),并且已在广泛的外周组织以及中枢神经系统中得到鉴定。尽管已经对其进行了大量研究,但是PBR的生理作用和功能仍不清楚。在本研究中,在探索新型的PBR配体时,我们发现由FGIN-1-27设计的一系列具有四环系统的新化合物对PBR表现出高亲和力。我们准备并评估了它们的PBR亲和力。结合测试的结果表明,12e和12f是其中最有效的PBR配体(12e:IC(50)= 0.44nM,12f:IC(50)= 0.37nM)。在本文中,我们介绍了设计,综合,
