Three novel jatrophane diterpenes, cyclojatrophanes A-C (1-3), were isolated from the seeds of Euphorbia peplus. Compounds 1-3 featured an unprecedented 5/5/5/11 tetracyclic ring system incorporating ditetrahydropyran rings. Their structures including their absolute configurations were established by extensive spectroscopic analysis, X-ray crystallographic experiments and chemical transformations. In addition, these compounds could significantly activate the lysosomal-autophagy pathway.
从泽漆种子中分离出三种新型麻风树烷二萜类化合物,即环麻风树烷A-C(1-3)。化合物1-3具有前所未有的5/5/5/11四环体系,包含二氢吡喃环。通过广泛的光谱分析、X射线晶体学实验和化学转化确定了它们的结构,包括其绝对构型。此外,这些化合物可显著激活溶酶体自噬途径。
