Tigloylgomisin H is a lignan isolated from the fruits of S. chinensis, can induce quinone reductase (QR) activity in Hepa1c1c7 mouse hepatocarcinoma cells. Tigloylgomisin H functions as a monofunctional inducer that specifically upregulates phase II detoxification enzyme NQO1 through the NF-E2-related factor 2 (Nrf2)-ARE pathway, thus represents a potential liver cancer prevention agent.
