AI Article Synopsis
- Five new triterpenes were isolated from the plant Viburnum hainanense, identified using various spectral methods like NMR and IR.
- The compounds were tested for their effectiveness against seven different tumor cell lines in vitro.
- Compounds 1 and 2 showed notable cytotoxic effects, with IC50 values below 10 μM, indicating strong potential for cancer treatment.
Article Abstract
Five new nor-dammarane triterpenes, 12β-O-acetyl-17β-hydoxy-3,15-dioxo-20,21,22,23,24,25,26,27-octanordammanran (1), 12β-hydoxy-17β-methoxy-3,15-dioxo-20,21,22,23,24,25,26,27-octanordammanran (2), 12β-O-acetyl-3,15-dioxo-17-en-20,21,22,23,24,25,26,27-octanordammanran (3), 12β-hydoxy-15α-O-acetyl-3-oxo-17-en-20,21,22,23,24,25,26,27-octanordammanran (4) and 3β-hydoxy-17-oxo-12-en-20,21,22,23,24,25,26,27-octanordammanran (5), were obtained from the ethanol extract of the whole plants of Viburnum hainanense Merr. et Chun. Structural elucidation of all the compounds was performed by spectral methods such as 1D and 2D NMR, IR, UV, and HRESIMS. The isolated compounds were tested in vitro for cytotoxic potential against seven tumor cell lines (Hep-2, SCL-1, CAL-27, UMSCC-1, Detroit-562, SCC-PKU, and TCA-83). As result, compounds 1 and 2 exhibited cytotoxic activities with IC50 values less than 10 μM.
