Microsomal activation, and SH-SY5Y cell toxicity studies of tremetone and 6-hydroxytremetone isolated from rayless goldenrod (Isocoma pluriflora) and white snakeroot (Agertina altissima), respectively.

This research compared the cytotoxic actions of the benzofuran ketone, tremetone in B16 murine melanoma cells to SH-SY5Y human neuroblastoma cells with an MTT assay. Tremetone was not cytotoxic in B16 cells. In SH-SY5Y cells, concentration-dependent tremetone cytotoxicity occurred without microsomal activation. No cytotoxicity was observed with 6-hydroxytremetone. This suggests that SH-SY5Y cells are a better model for the cytotoxic actions of tremetone and that tremetone is toxic without microsomal activation.
