名称:
Saikachinoside A, a novel 3-prenylated isoguanine glucoside from seeds of Gleditsia japonica
摘要:
A new isoguanine glucoside designated saikachinoside A has been isolated from the seeds of Gleditsia japonica. The structure was determined as 7-beta-D-glucopyranosyl-3-[(Z)-4-hydroxy-3-methyl-2-butenyl]isoguanine by interpretation of the spectroscopic data and was confirmed by X-ray crystallographic analysis.

杜氏甲虫 Bruchidius dorsalis 在皂荚种子内构建的蛹壳中的硫酸化嘌呤生物碱糖苷
摘要:
三种新的硫酸化异鸟嘌呤生物碱糖苷,命名为 saikachinoside A 单硫酸盐 (1)、saikachinoside A disulfate (2) 和 locustoside B disulfate (3),已从野生 bruchid 种子甲虫 Bruchidius dorsalis (Chrysomelidae, Bruchidius dorsalis (Chrysomelidae, Bruchidius dorsalis) 的蛹壳中分离出来) 侵染皂角的种子。(豆科)。它们的结构通过光谱方法确定,并评估了 2 和 3 对酸性磷酸酶的抑制活性。
