Trehangelin E(1)是从放线菌polymorphosporasp的培养提取物中分离得到的一种新的双酰基海藻糖。化合物1是一种新的海藻糖衍生物，经核磁共振和质谱分析，它与(Z)-2-甲基-2-丁烯酸（天使酸）在3-和6 -位上酰化。与未处理的种子相比，化合物1在1 μM和10 μM处理下使发芽莴苣种子的根伸长分别提高了30%和90%。在相同水平上，翠绿素A和B对根伸长的促进作用相似。
Trehangelin E (1), a new bisacyl trehalose, was isolated from the culture extract of an actinomycetePolymorphosporasp. RD064483, along with three known congeners, trehangelins A, B, and D. Compound1is a new trehalose derivative acylated with (Z)-2-methyl-2-butenoic acid (angelic acid) at 3- and 6ʹ-positions, as determined by NMR and MS analyses. Compound1promoted root elongation of germinated lettuce seeds by 30% at 1 μM and 90% at 10 μM compared to the nontreated seeds. Similar promoting activity of root elongation was also observed with trehangelins A and B at the same level.
