Absolute structure assignment of an iridoid-monoterpenoid indole alkaloid hybrid from Dipsacus asper.
Iridoid-monoterpenoid indole alkaloid hybrids (IMIAHs) represent a rare class of natural products reported from only several plants of Rubiaceae and Dipsacaceae families, while their structural assignments remain a very challenging work due to complexity and flexibility. In the current study, a new IMIAH (1) was isolated from the roots of Dipsacus asper and its structure with absolute configuration was unambiguously established by a combination of spectroscopic analyses, chemical degradation and ECD calculation. A new oleanane-type triterpenoid saponin (2) and 15 known co-metabolites were also obtained and structurally characterized. Our biological evaluations showed that compound 2 exhibited moderate inhibition against acetylcholine esterase (AChE) with an IC Topics: Cell Line, Tumor; Cell Survival; Dipsacaceae; Glucosides; Humans; Iridoids; Molecular Structure; Oleanolic Acid; Plant Roots; Secologanin Tryptamine Alkaloids | 2019 |
