guanidine-based systems, offering a versatile preparation of substituted imidazoles. The direct comparison of the anticancer activity of all naturally occurring (−)-agelastatins in addition to eight advanced synthetic intermediates enabled a systematic analysis of the structure–activity relationship within the natural series. Significantly, (−)-agelastatin A (1) is highly potent against six blood cancer
( - ) - agelastatins A-F(我们的对映选择性全合成的全部细节1 - 6),描述了合成取代氮杂杂环的新方法的演变,以及所有已知 (-)-agelastatin 生物碱对九种人类癌细胞系的首次并列评估。我们对这些生物碱的简明合成利用了合理的生物合成前体的内在化学,并利用了 C 环的后期合成。关键的铜介导的交叉偶联反应被扩展到包括基于胍的系统,提供了取代咪唑的通用制备。除了八种高级合成中间体之外,所有天然存在的 (-)-agelastatins 的抗癌活性的直接比较使得能够对天然系列内的结构-活性关系进行系统分析。值得注意的是,(-)-agelastatin A ( 1) 对六种血癌细胞系 (20–190 nM) 具有高度效力,而不会影响正常红细胞 (>333 μM)。(-)-Agelastatin A ( 1 ) 和 (-)-agelastatin D ( 4 ) 是该家
