Odor: characteristic Use: Pectolinarin and pectolinarigenin also increased activity levels of glutathione (GSH), glutathione reductase (GR), gamma-glutamylcysteine synthetase (GCS) and glutathione S-transferase (GST), as well as superoxide dismutase (SOD). The significant effect was only seen in SOD activity. This suggests that the two components exhibit hepatoprotective activity mainly via SOD antioxidant mechanism.
Pectolinarigenin strongly inhibited cyclooxygenase-2 (COX-2)-mediated prostaglandin E2 (PGE2) and 5-lipoxygenase (5-LOX)-mediated leukotriene (LT) production at >1 microM, indicating that it is a dual inhibitor of COX-2/5-LOX. However, pectolinarigenin did not affect COX-2 expression or nuclear transcription factor (NF-kappaB) activation. In addition, in vivo studies demonstrated that oral administration of these two compounds at 20-100 mg/kg resulted in similar inhibitory activities against several animal models of inflammation/allergy: arachidonic acid-induced mouse ear edema, carrageenan-induced mouse paw edema and passive cutaneous anaphylaxis. All of these results suggest that pectolinarigenin and pectolinarin possess anti-inflammatory activity and that they may inhibit eicosanoid formation in inflammatory lesions. These activities certainly contribute to the anti-inflammatory mechanism of C. chanroenicum. |
