we report the synthesis of four new phenyl alkyl ether derivatives (7, 9–11) of the pyrazolo[1,5-a]pyrimidine acetamide class, all of which showed high binding affinity and selectivity for the TSPO and, in the case of the propyl, propargyl, and butyl ether derivatives, the ability to increase pregnenolone biosynthesis by 80–175% over baseline in rat C6 glioma cells. While these compounds fit our in silico
此,我们报告的四个新的苯基烷基醚衍生物(合成7,9 - 11)的吡唑并[1,5-一个]嘧啶乙酰胺类,所有这些都显示出高结合亲和力和选择性的TSPO,并且在在丙基,炔丙基和丁基醚衍生物的情况下,大鼠C6胶质瘤细胞中孕烯醇酮生物合成的能力比基线提高80-175%。虽然这些化合物适合我们的计算机生成的TSPO结合药效基团,但当前模型无法说明观察到的功能活性。
