The present paper reports the synthesis and binding studies of new 2-phenylpyrazolo[1,5-a]pyrimidin-3-yl acetamides as selective Peripheral Benzodiazepine Receptor (PBR) ligands. The variability of substituents at the 3-position was investigated and a 3D-QSAR model was proposed to evaluate the effect of different substitutions on the acetamide moiety. In addition, a subset of the novel compounds showing high affinity for PBR was tested for their ability to modulate the steroid biosynthesis in C6 glioma cells.
本文报道了新型2-苯基吡唑并[1,5-a]嘧啶-3-基乙酰胺作为选择性外周苯二氮䓬受体（PBR）配体的合成及结合研究。研究了3-位取代基的变化情况，并提出了一个3D-QSAR模型来评估不同取代基对乙酰胺部分的影响。此外，还测试了对PBR具有高亲和力的一部分新型化合物调节C6胶质瘤细胞中类固醇生物合成的能力。
