Pectolinarigenin is an orally active dual inhibitor of COX-2/5-LOX with anti-inflammatory, antioxidant, antitumor and neuroprotective activities. Pectolinarigenin exerts neuroprotective and anti-inflammatory effects on astrocyte inflammation via the NFκB and MAPK pathways. Pectolinarigenin inhibits LPS-induced phosphorylation of ERK1/2, N-FκB and p38MAPK, directly inhibits the enzymatic activity or binding of COX-2, 5-LOX and HIF-1α, and reduces the level of XIAP. Pectolinarigenin modifies Keap1 to promote nuclear accumulation of Nrf2, induces ARE-mediated antioxidant enzyme expression, and possesses direct free radical scavenging activity. Pectolinarigenin reduces the release of NO, proinflammatory mediators and leukotrienes, and increases the level of IL-10. Pectolinarigenin induces G2/M cell cycle arrest, apoptosis (Apoptosis) and autophagy (Autophagy) via the PI3K/AKT/mTOR signaling pathway. Pectolinarigenin reduces renal crystal deposition and inhibits melanin synthesis. Pectolinarigenin inhibits inflammation and alleviates allergy in mouse models of inflammation. Pectolinarigenin alleviates renal injury, inflammation and oxidative stress in mice by inhibiting HIF-1α activity. Pectolinarigenin can be used for the research of neurodegenerative diseases, inflammatory/allergic diseases, calcium oxalate nephrocalcinosis, gastric cancer, melasma, post-inflammatory diseases and chloasma .
