Five new prenylated chalcones from Desmodium renifolium.

Area of Science:

• Natural Product Chemistry
• Pharmacology
• Medicinal Plant Research

Background:

• Desmodium renifolium is a plant with potential medicinal properties.
• Prenylated chalcones are a class of natural compounds with diverse biological activities.

Purpose of the Study:

• To isolate and characterize new prenylated chalcones from Desmodium renifolium.
• To evaluate the cytotoxic activity of these compounds against various tumor cell lines.

Main Methods:

• Isolation of compounds using chromatographic techniques.
• Structure elucidation using 1D and 2D Nuclear Magnetic Resonance (NMR) spectroscopy.
• Cytotoxicity assays using five human tumor cell lines.

Main Results:

• Five new prenylated chalcones, named renifolins D-H (compounds 1-5), were successfully isolated and identified.
• Compounds 2 and 3 demonstrated notable cytotoxicity against A549 lung cancer cells.
• The IC50 values for compounds 2 and 3 against A549 cells were 2.8 μM and 2.2 μM, respectively.

Conclusions:

• Desmodium renifolium is a source of novel prenylated chalcones with potential anticancer properties.
• Renifolins D and E (compounds 2 and 3) exhibit promising cytotoxicity against A549 cells, warranting further investigation.
