GtoPdb Ligand ID: 9675

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Andrographolide is a major component of the leaves of the traditionally used medicinal plant Andrographis paniculata (Acanthaceae) [6]. Andrographolide and analogues are being investigated for their potential anti-inflammatory activities [4], but andrographolide has also shown anti-viral, anti-thrombotic, hepatoprotective and anti-cancer properties [6]. Accumulated evidence indicates that the principal mechanism undelying andrographolide's anti-inflammatory action is inhibition of NF-κB. Additional studies show that Nrf2 activation by andrographolide likely enhances endogenous antioxidant defense mechanisms. Direct covalent interaction with Cys62, and non-covalent binding are both required for andrographolide-induced inhibition of NF-κB p50 [3].
