According to a study published by "Organic letters", the aerial parts of Premna fulva were used to isolate Premnafulvol A (1), which features a unique 6/5/7/3-fused tetracyclic carbon skeleton. Three biosynthetically related analogues, known as premnafulvols B-D (2-4), were also isolated from these plant parts. Structures for 1-4 were established using extensive spectroscopic analyses, quantum chemical calculations, and X-ray crystallography. Regarding medicinal interest, 2 and 3 exhibited opposite effects on estrogen biosynthesis in human ovarian granulosa-like KGN cells. These effects were achieved by modulating the expression of aromatase.
