topostins, a novel type of mammalian DNA topoisomerase I inhibitors isolated from the bacterium Flexibacter topostinus sp. nov., have remained unknown. Reexamination of the production of topostins resulted in the isolation of original topostins B (B553 (1) and B567 (2)) and new related compounds named topostins D (D640 (3) and D654 (4)). Their structures, including the absolute stereochemistry, were determined
topostins的结构,一种从细菌Flexibacter topostinus sp。分离的新型哺乳动物DNA拓扑异构酶I抑制剂。十一月。,仍然未知。重新检查topostins的产生导致分离出原始topostins B(B553(1)和B567(2))和名为topostins D的新相关化合物(D640(3)和D654(4))。它们的结构,包括绝对立体化学,是通过光谱分析和化学降解来确定的。这些物质是含脂质的氨基酸和肽。
