In this paper, we report the synthesis and cell-based anti-prion activity of quinacrine analogs derived by replacing the basic alkyl side chain of quinacrine with 4-(4-methylpiperazin-I-yl)phenyl, (1-benzylpiperidin-4-yl) and their structural variants. Several promising analogs were found that have a more favorable anti-prion profile than quinacrine in terms of potency and activity across different
在本文中,我们报道了用4-(4-甲基哌嗪-1-基)苯基,(1-苄基哌啶-4- yl)及其结构变体。发现在不同different病毒感染的鼠细胞模型的效价和活性方面,一些有前途的类似物在抗病毒方面比奎纳克林更有利。它们还表现出对人类病毒蛋白片段的更高结合亲和力(hPrP 121–231)比奎纳克林高,并且在PAMPA-BBB分析中的渗透率在CNS渗透候选物范围内。当在过表达Pgp的细胞系上进行双向分析评估时,与奎纳克林相比,一种类似物对Pgp外排活性的敏感性较低。两者合计,结果表明连接到a啶,四氢ac啶和喹啉骨架上的取代9-氨基侧链的重要作用。该侧链的性质影响基于细胞的效能,PAMPA渗透性和对hPrP 121-231的结合亲和力。
