- To evaluate the cytotoxic activities of the isolated compounds.
Main Methods
- Isolation of compounds using chromatographic techniques.
- Structure elucidation via extensive spectroscopic analysis and X-ray crystallography.
- Cytotoxicity assays against Vero and A549 cell lines.
Main Results
- Seven polyketides were isolated, including a novel depsidone (1) and six known compounds (2-7).
- Compound 1 was characterized by spectroscopic methods and X-ray crystallography.
- Compounds 1 and 7 demonstrated weak cytotoxic effects against Vero and A549 cells, with IC50 values ranging from 95.6 to 296.5 μM.
Conclusions
- Penicillium robsamsonii HNNU0006 produces a range of polyketides, including a new depsidone.
- The isolated compounds, particularly 1 and 7, possess weak cytotoxic potential warranting further investigation.
