Antineoplastic 31-norcycloartanones from Solanum cernuum vell

Area of Science:

• Phytochemistry
• Pharmacology
• Natural Products Chemistry

Background:

• The Solanum genus is a rich source of bioactive compounds.
• Triterpenoids are a diverse class of natural products with various pharmacological activities.
• Investigating novel compounds from Solanum species can lead to new therapeutic agents.

Purpose of the Study:

• To isolate and characterize triterpenoids from Solanum cernuum leaves.
• To evaluate the cytotoxic activity of isolated compounds against human tumor cell lines.
• To assess the antiulcer activity of the Solanum cernuum dichloromethane extract.

Main Methods:

• Isolation and structure elucidation of triterpenoids using chromatographic and spectroscopic techniques.
• In vitro cytotoxic assays against human tumor cell lines (e.g., NCI-H460).
• In vivo antiulcer assays using ethanol and indomethacin-induced gastric ulcer models.

Main Results:

• 24-oxo-31-norcycloartanone, a novel 31-norcycloartanone triterpenoid, was isolated and identified as a major constituent.
• 24-oxo-31-norcycloartanone exhibited significant and selective cytotoxicity against the NCI-H460 lung tumor cell line.
• The dichloromethane extract showed dose-dependent inhibition of gastric lesions induced by ethanol, but limited activity against indomethacin-induced ulcers.

Conclusions:

• Solanum cernuum is a source of novel triterpenoids with potential anticancer properties.
• 24-oxo-31-norcycloartanone is a promising candidate for further development as an anti-lung cancer agent.
• The plant extract possesses antiulcer activity, warranting further investigation into its mechanisms and active components.
