Hispidulin is a natural flavanoid which acts as a potent benzodiazepine (BZD) receptor ligand. In addition, hispidulin competitively binds to the benzodiazepine receptor, thus inhibiting 3H-Flumazenil from binding to the receptor. Furthermore, it has been observed that hispidulin has antioxidant, antithrombotic, antifungal, and antiproliferative properties. Alternate studies indicate that hispidulin can inhibit the PI3K/Akt/mTOR signaling pathway in endothelial cells by targeting VEGF receptor 2. Inhibition of this receptor by hispidulin suppressed cell migration, invasion, and capillary-like structure formation of HU-VE-Cs in vascular endothelial cells. Hispidulin also aactivates AMPK.
