Summary
Physalin F from Physalis angulata demonstrated potent anticancer activity against multiple cancer cell lines and in vivo leukemia models. Physalin D showed no significant activity, highlighting physalin F as a promising therapeutic candidate.
Area of Science:
- Phytochemistry
- Pharmacology
- Natural Products
Background:
- Physalis angulata L. (Solanaceae) is a plant with traditional medicinal uses.
- Natural compounds from plants are a rich source of potential therapeutic agents.
- Cytotoxic and antitumor compounds are actively sought for cancer treatment.
Purpose of the Study:
- To isolate and characterize active compounds from Physalis angulata.
- To evaluate the in vitro and in vivo anticancer potential of isolated compounds.
- To identify specific cancer types most responsive to the active compounds.
Main Methods:
- Ethanolic extraction of the whole Physalis angulata plant.
- Systematic fractionation of the extract to isolate compounds.
- In vitro cytotoxicity assays (DEA and MTT) on 8 human and animal cancer cell lines.
- In vivo antitumor assay against P388 lymphocytic leukemia in mice.
Main Results:
- Physalin F was isolated and identified as a key active ingredient.
- Physalin F exhibited significant in vitro cytotoxicity against hepatoma (HA22T) and cervical cancer (HeLa) cell lines.
- Physalin F demonstrated in vivo antitumor activity against P388 lymphocytic leukemia in mice.
- Physalin D was found to be inactive in both in vitro and in vivo assays.
Conclusions:
- Physalin F is a potent cytotoxic and antitumor compound isolated from Physalis angulata.
- Physalin F shows selective activity, with the strongest effects against hepatoma and cervical cancer.
- Physalin F warrants further investigation as a potential natural-based cancer therapeutic.
