Magnolol is a dual agonist of both RXRα and PPARγ, with EC50 values of 10.4 μM and 17.7 μM, respectively. Magnolol has antifungal, antibacterial, anti-oxidative, antidepressant-like, anti- tumor, and neuroprotective effects, it also prevents skin photoaging in UVB-irradiated hairless mice. Magnolol has a wide spectrum of targets including TNF-α, NF-KB, GSK3β.

Salvianolic acid and notoginseng triterpenes can promote EA-hy926 and expression of protein, have protective effects on angiogenesis in EA-hy926 cells in vitro.

Silydianin, an active constituent of Silybium marianum, has inhibitory effect on on the in vitro production and release of oxidative products. Silydianin has possible antiinflammatory activity, which regulates caspase-3 activation, affects cell membranes and acts as a free radical scavenger.

Flavokawain B, the hepatotoxic constituent from kava root, induces GSH-sensitive oxidative stress through modulation of IKK/NF-κB and MAPK signaling pathways. Flavokawain B has potent anti-inflammatory, and anti-cancer activities, it can significantly inhibit production of NO and PGE2 in LPS-induced RAW 264.7 cells. Flavokawain B acts through ROS generation and GADD153 up-regulation to regulate the expression of Bcl-2 family members, thereby inducing mitochondrial dysfunction and apoptosis in HCT116 cells.
