本文报道了两个新的三环倍半萜类化合物shagenes A(1)和B(2)的分离和表征。这些化合物是从南大洋斯科舍弧收集的一种未描述的软珊瑚中分离出来的。一维和二维核磁共振波谱和质谱提供了表征化合物及其相对立体化学构型所需的数据。对shagenes A和B生物活性的探索发现,其中1种对内脏利什曼病病原利什曼原虫(Leishmania donovani)有活性,对哺乳动物宿主无细胞毒性。
The isolation and characterization of two new tricyclic sesquiterpenoids, shagenes A (1) and B (2) are presented. These compounds were isolated from an undescribed soft coral collected from the Scotia Arc in the Southern Ocean. One- and two-dimensional NMR spectroscopy and mass spectrometry provided the data necessary to characterize the compounds and their relative stereochemical configurations. Exploration of the bioactivity of shagenes A and B found 1 active against the visceral leishmaniasis causing parasite, Leishmania donovani, with no cytotoxicity against the mammalian host.
