Summary
Five new and three known ursane-type triterpenoids were isolated from Clerodendranthus spicatus. Most compounds inhibited cell proliferation in rat kidney fibroblast cells, with compound 2 showing the most activity.
Area of Science:
- Natural Product Chemistry
- Pharmacology
Background:
- Clerodendranthus spicatus is a plant source of bioactive compounds.
- Triterpenoids are a diverse class of natural products with various biological activities.
Purpose of the Study:
- To isolate and characterize new triterpenoids from Clerodendranthus spicatus.
- To evaluate the biological activity of isolated triterpenoids against kidney and cancer cells.
Main Methods:
- Isolation of compounds using chromatographic techniques.
- Structure elucidation by spectroscopic methods (NMR, MS) and X-ray crystallography.
- Cell viability assays (MTT, MST) to assess antiproliferative effects.
Main Results:
- Five new ursane-type triterpenoids (spicatusoids A-E) and four known triterpenoids were identified.
- Compounds 2, 3, 4, 5, 6, 7, 8, and 9 inhibited proliferation of TGF-β1-induced NRK-49F cells.
- Compound 2 exhibited the most potent inhibitory activity against NRK-49F cells.
Conclusions:
- The study successfully isolated and characterized novel triterpenoids from Clerodendranthus spicatus.
- The isolated triterpenoids, particularly compound 2, demonstrate potential as antiproliferative agents against kidney fibroblast cells.
