Inulin is an orally active prebiotic targeting the intestinal microbiota, selectively promoting the proliferation and activity of beneficial bacteria such as bifidobacteria and lactic acid bacteria, and playing a role in regulating the intestinal microecology. The functions of Inulin include: Fermentation by probiotics in the colon to produce short-chain fatty acids (such as butyrate and propionate), lowering the intestinal pH and inhibiting the overgrowth of harmful bacteria; Enhancing the intestinal barrier function and reducing endotoxin translocation; Directly scavenging free radicals (such as superoxide free radicals, hydroxyl free radicals) and activating antioxidant enzymes (SOD, CAT) to reduce oxidative stress. Inulin can also be used in the study of intestinal diseases (constipation, IBD), metabolic syndrome (diabetes, obesity) and liver damage by regulating glucose and lipid metabolism (such as reducing triglycerides, improving insulin sensitivity) and immune response (enhancing NK cell activity, inhibiting inflammatory factors)[1][2][3][4].

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.
