Summary

Five isopimarane diterpenes from Hypoestes serpens leaves show antifungal activity against plant pathogens and yeast. Two compounds also inhibit acetylcholinesterase, suggesting potential therapeutic applications.

Area of Science:

Phytochemistry
Natural Products Chemistry
Pharmacology

Background:

Hypoestes serpens (Acanthaceae) is a plant species with potential medicinal properties.
Diterpenes are a class of natural products known for diverse biological activities.

Purpose of the Study:

To isolate and characterize chemical constituents from Hypoestes serpens leaves.
To evaluate the isolated compounds for antifungal and enzyme inhibitory activities.

Main Methods:

Isolation of compounds using chromatographic techniques.
Structure elucidation via spectroscopic methods (1D/2D NMR, MS).
Biological assays for antifungal activity (Cladosporium cucumerinum, Candida albicans) and acetylcholinesterase inhibition.

Main Results:

Five isopimarane diterpenes were successfully isolated and identified.
All five compounds demonstrated antifungal activity against tested fungi.
Two of the isolated diterpenes exhibited acetylcholinesterase inhibition.

Conclusions:

Hypoestes serpens is a source of bioactive isopimarane diterpenes.
These compounds possess significant antifungal properties and potential for enzyme inhibition.
Further research may explore their therapeutic potential.
