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.

Chrysin 6-C-glucoside 8-C-arabinoside and Chrysin-6-C-arabinosyl-8-C-glucoside are α±-glucosidase inhibitors widely used in the treatment of type 2 diabetes.

Scutellarein tetramethyl ether (4',5,6,7-Tetramethoxyflavone) is extracted from Siam weeds and demonstrates anti-inflammatory activity via the NF-κB pathway.

1. Malic acid (Pomalus acid) did reduce populations of L. monocytogenes on poultry. 2. Malic acid supplementation may be useful for conservative treatment of calcium renal stone disease by virtue of its capacity to induce these effects.

5-Hydroxy-7-acetoxy-8-methoxyflavone is a flavonoid compound that inhibits lipid peroxidation and may exhibit anti-influenza virus activity.
