According to a study published by "Pharmaceuticaal biology", the leaves of Premna serratifolia were used to isolate cytotoxic terpenoids and steroids. Three specific compounds, PS-01 A, PS-01 B, and PS-02 A, were isolated from the leaf extract through bioactivity-guided fractionation. These compounds showed cytotoxicity in a BSL bioassay with LC50 values of 54.49, 30.83, and 16.32 ppm, respectively. In cell line studies, PS-02 A demonstrated higher cytotoxicity with LC50 values of 66.77 μg/mL for A549 cells and 53.72 μg/mL for HepG2 cells. The study successfully isolated two terpenoids and one steroid from the leaves that could potentially be developed as anticancer agents.

According to a study published by "Phytotherapy research : PTR", Premna serratifolia Linn. is a member of the Verbenaceae family that is extensively used in the Ayurvedic system of medicine in India. Researchers screened methanolic extracts of leaves, root bark (RB), and root wood for activity against 2 cancer cell lines, specifically SHSY-5Y neuroblastoma and B16 melanoma cells. An isolated novel compound showed cytotoxic activity that was 21 times higher against SHSY-5Y cells and 23 times higher against B16 cells than the crude extract. This compound also demonstrated antioxidant effects with a DPPH radical scavenging IC50 value of 20.4 ± 1.3 μM. For comparison, the positive control caffeic acid exhibited an IC50 value of 14.4 ± 1.6 μM.
