Biological Activities
Vernonia pachyclada, a plant native to the Madagascar rainforest, has demonstrated significant biological potential through its cytotoxic properties. Researchers utilized bioassay-guided fractionation of leaf extracts to isolate several unique sesquiterpene lactones. Among these findings, three new compounds known as glaucolides K-M were identified and characterized using advanced spectroscopy. Structural analysis, including single-crystal X-ray diffraction, helped confirm the precise stereochemistry of these specialized molecules. Notably, compound 3 exhibited moderate cytotoxic activity against the A2780 human ovarian cancer cell line, marking it as a subject of pharmacological interest.
