    Area of Science:

    • Natural Products Chemistry
    • Pharmacology

    Background:

    • Daphne altaica is a plant species known to produce bioactive compounds.
    • Daphnane diterpenoids are a class of natural products with diverse biological activities.

    Purpose of the Study:

    • To isolate and characterize new daphnane diterpenoids from Daphne altaica.
    • To evaluate the antiproliferative activity of isolated compounds against human lung carcinoma.

    Main Methods:

    • Isolation of compounds using chromatographic techniques.
    • Structure elucidation using 1D and 2D Nuclear Magnetic Resonance (NMR) data.
    • Antiproliferative activity assay against A549 cell line.

    Main Results:

    • Three new daphnane diterpenoids, named altadaphnans A-C, were identified.
    • Seven known daphnane diterpenoids were also isolated.
    • Altadaphnans A-C exhibited significant antiproliferative effects on A549 human lung carcinoma cells.

    Conclusions:

    • Daphne altaica is a source of novel daphnane diterpenoids.
    • Altadaphnans A-C possess promising anticancer potential for lung carcinoma treatment.
