American medicinal plant, V. thapsus L., as a candidate of an anti-allergic lead which inhibits the expression of high-affinity receptor of IgE (FcεRI) on the surface of mast cells. Furthermore, the analysis of structure-activity relationship by using synthesized 2′,3′-dihydroxypuberulin analogs revealed that both hydroxy groups in the side chain and both of methyl moieties on phenolic hydroxy groups
我们从南美药用植物V. thapsus L.中发现了2',3'-二羟基青春素,作为抗过敏铅的候选物,该铅抑制了IgE(FcεRI)高亲和力受体在桅杆表面的表达细胞。此外,通过使用合成的2',3'-二羟基青春粉蛋白类似物进行的结构-活性关系分析表明,侧链上的两个羟基以及酚羟基上的甲基均对有效活性至关重要,但C-的绝对构型3'的位置不是。公开了活性成分2',3'-二羟基青春粉蛋白,其下调FcεRI的β链的mRNA水平,这与先前报道的降低γ链水平的活性天然产物不同。
