A novel naturally occurring compound with a benzofuran skeleton was isolated from a plant, Tephrosia purpurea collected in Bangladesh. The chemical synthesis of this compound confirmed its structure, and preliminary biological results showed its suppressive activity towards histamine H1 gene expression. One isomer and four derivatives were also synthesized, and their suppression activity was investigated
从孟加拉国收集的一种植物Tephrosia purpurea中分离出了一种具有苯并呋喃骨架的新型天然化合物。该化合物的化学合成证实了其结构,初步的生物学结果表明其对组胺H 1基因表达具有抑制活性。还合成了一种异构体和四种衍生物,并研究了它们的抑制活性。尽管只能从其天然来源中分离出少量这种化合物,但新开发的方法证明了10 g规模的合成。
