Implication

In vitro study reveals potent cytotoxic activity of gelsedine-type indole alkaloids against human epidermoid carcinoma cells, highlighting their potential as anticancer chemical scaffolds.

Key Points

To isolate novel gelsedine-type indole alkaloids from the leaves of Gelsemium elegans and assess their cytotoxic potential against human epidermoid carcinoma cells.
Extracted and purified chemical constituents from Gelsemium elegans leaves, establishing structures via spectroscopic analysis.
Screened 14 isolated Gelsemium alkaloids, including two newly identified compounds, for cytotoxicity against the A431 human epidermoid carcinoma cell line.
Characterized four new gelsedine-type indole alkaloids—14-acetoxygelsenicine, 14-acetoxy-15-hydroxygelsenicine, 14-hydroxy-19-oxogelsenicine, and 14-acetoxygelselegine—along with 11 known alkaloids.
Identified potent cytotoxic effects against A431 carcinoma cells specifically among the gelsedine-type alkaloids 14-acetoxy-15-hydroxygelsenicine, 14,15-dihydroxygelsenicine, gelsedine, and gelsemicine.
