We investigated the constituents of Dictyostelium discoideum to clarify the diversity of secondary metabolites of Dictyostelium cellular slime molds and to explore biologically active substances that could be useful in the development of novel drugs. From a methanol extract of the multicellular fruit body of D. discoideum, we isolated two novel amino sugar analogues, furanodictine A (1) and B (2).
我们调查了盘基网柄菌的成分,以阐明盘基网柄细胞粘液霉菌的次生代谢产物的多样性,并探索可用于开发新药的
生物活性物质。从D. discoideum的多细胞子实体的
甲醇提取物中,我们分离了两个新的
氨基
糖类似物,
呋喃果苦碱A(1)和B(2)。它们是最早从天然来源中分离出来的3,6-脱
水糖。通过光谱方法阐明了它们的相对结构,并通过1和2的不对称合成证实了其绝对构型。这些
呋喃西汀可有效诱导大鼠嗜
