23-epi-26-Deoxyactein (27-Deoxyactein) has anti-inflammatory activity, it inhibits nitric oxide production by reducing iNOS expression without affecting activity of the enzyme. It also has anti-cancer activity, it can inhibit growth of the MCF7 human breast cancer cells and induce cell cycle arrest at G1.

1. Negletein (7-O-Methylbaicalein) has anti-inflammatory and immunomodulatory activities via inhibition of TNF-α, iNOS and IL-1β. 2. Negletein as a neuroprotectant enhances the action of nerve growth factor and induces neurite outgrowth in PC12 cells. 3. Negletein shows a comparable redox-active potential, and it (50 μM, 4 h) can activate Nrf2. 4. Negletein shows significant antimicrobial activity. 5. Negletein has anti-hypoxia activity, it can significantly prolong the survival time of hypoxic mice.6. Negletein has anti- Alzheimer's disease activity, it inhibits the iron-dependent formation of ROS and also blocks the iron-induced oligomerization of amyloid beta 42 in vitro. 7. Negletein (IC50: 3.89 +/- 0.39 microM) exhibits potent inhibitory activity against nuclear factor of activated T cells (NFAT) transcription factor.

GW274150 phosphate is a selective, orally active, and NADPH-dependent inhibitor of human inducible nitric oxide synthase (iNOS) (IC50: 2.19 μM; Kd: 40 nM) and rat iNOS (ED50: 1.15 μM).

Xanthoxyletin shows potent antibacterial, fungicidal, and algicidal properties, it also has anticancer, and anti-inflammatory activities. It shows an inhibitory effect on iNOS protein expression at 10 microM, it also can inhibit the synthesis of nitric oxide and the protein expression of tumor necrosis factor-alpha and cyclooxygenase-2. Xanthoxyletin induces S phase arrest and apoptosis in human gastric adenocarcinoma SGC-7901 cells, the effects are associated with the DNA damage, apoptosis through mitochondrial dysfunction, and cell cycle arrest at S phase in a dose-dependent manner, it also can increase the production of reactive oxygen species.

Regaloside B, a phenylpropanoid isolated from Lilium longiflorum, exhibits anti-inflammatory activity by inhibiting the expression of iNOS (inducible nitric oxide synthase) and COX-2 (cyclooxygenase-2).
