four known compounds: (1S,3R)-austrocortirubin (1), (1S,3S)-austrocortirubin (2), 1-deoxyaustrocortirubin (3), and austrocortinin (4). Compound 2 was used as a natural product scaffold in the parallel solution-phase synthesis of a small library of N-substituted tetrahydroanthraquinones (5–15). All compounds (1–15) were tested in vitro against P. falciparum 3D7 parasites and (1S,3S)-austrocortirubin (2)
作为一项旨在从澳大利亚大型真菌中发现新的抗疟疾线索的研究计划的一部分,使用放射生长抑制测定法针对
氯喹敏感的恶性疟原虫品系(3D7)筛选了一种独特的真菌衍生的预分离文库。衍生自Cortinarius物种的文库级分显示出有希望的抗疟活性。在该真菌的CH 2 Cl 2 / MeOH
提取物上进行紫外线引导分馏,分离出四种已知化合物:(1 S,3 R)-aucortrocortirubin(1),(1 S,3 S)-austrocortirubin(2) ,1-deoxyaustrocortirubin(3)和austrocortinin(4)。化合物2在小的N取代的四氢
蒽醌文库(5-15)的平行溶液相合成中用作
天然产物支架。所有化合物(1 - 15)在体外测试针对恶性疟原虫3D7寄生虫和(1小号,3小号)-austrocortirubin(2),主要的真菌成分,被证明是与IC最活跃的化合物50 1
