Two series of territrem B analogues (10a-10c and 18) have been designed and synthesized from jujubogenin 5a which was prepared from jujubogenin glycosides 5b obtained from the leaves of Zizyphus jujuba. The structures of the new compounds were confirmed by ¹H-,¹³C-NMR and MS data. Compounds 10c and 18 showed weak inhibitory effect on AChE at 10^-4mol/L.
- Territrem B analogues,
- acetylcholinesterase (AChE) inhibitor,
- jujubogenin.
