We here disclose the total syntheses of the natural polyphenol JBIR-94 and two nonnatural analogs, whose structures are of interest for their bioactivity potential as radical scavengers. Although we initially attempted this by dually acylating both of putrecine’s amine nitrogens in a single pot, our endeavors with this method (which has been successfully reported by other groups) proved ineffectual
我们在这里公开了天然多酚JBIR-94和两种非天然类似物的总合成,其结构因其作为自由基清除剂的生物活性而受到关注。尽管我们最初是通过在一个锅中双重酰化两个腐胺的胺氮来尝试这种方法,但是我们采用这种方法(已被其他小组成功报道)的努力被证明是无效的。因此,我们选择了更长的方法,使每种胺单独酰化,这是很受欢迎的,并且也与单独的文献先例相符。此外,我们在这里分享了我们对这些目标化合物针对A549(CCL-185)人小肺癌细胞的细胞毒性和IC 50值的分析。
