synthesized and tested novel pyridopyrrolo- and pyrrolobenzoxazepine derivatives, as novel and selective peripheral type benzodiazepine receptor (PBR) ligands, and their ability to modulate steroid biosynthesis has been investigated. A subset of new ligands bind the PBR (rat brain and testis) with picomolar affinity, representing the most potent ligands that have been identified to date, and elicited effects
在本研究中,我们已经合成并测试了新颖的吡咯并吡咯并吡咯并吡咯并a庚因衍生物,作为新颖的和选择性的外周型苯并二氮杂receptor受体(PBR)配体,并研究了它们调节类固醇生物合成的能力。一组新的配体以皮摩尔亲和力结合了PBR(大鼠的大脑和睾丸),代表了迄今已鉴定出的最有效的配体,并引起了对MA10 Leydig细胞中类固醇生成的内源性速率的作用,具有与PK11195相似的效力和作用。 。使用几种在C-7处不同取代的化合物作为分子标准,以探测受体结合位点中亲脂性口袋L4的空间尺寸。
