Oxopurpureine
Oxyberberine (Oxyberberin; Berlambine) is an orally effective heme oxygenase HO-1 agonist that can activate antioxidant mechanisms by regulating the PI3K/Akt/AMPK signaling pathway. Oxyberberine induces HO-1 expression, increases SOD and GSH-Px activity, inhibits NF-κB-mediated inflammatory responses, and improves insulin sensitivity and glucose metabolism. Oxyberberine has anti-diabetic, neuroprotective, anti-inflammatory and antioxidant effects, and can be used to study type 2 diabetes, traumatic brain injury (TBI) and inflammatory bowel disorder[1][2][3].
