Limonin Powder CAS 1180-71-8

1. Activating the Nrf2 antioxidant pathway and scavenging free radicals:

It can drive the translocation of Nrf2 protein to the cell nucleus, upregulate the expression of endogenous antioxidant proteins such as HO-1, SOD, and glutathione, directly neutralize intracellular reactive oxygen species, reduce the accumulation of oxidative metabolic byproducts, reduce mitochondrial oxidative damage, stabilize the intracellular oxidative balance, and alleviate oxidative stress damage caused by various external stimuli.

2. Regulating the NF-κB and AMPK/mTOR pathways and alleviating local stress signals:

It blocks TLR4-mediated NF-κB signaling, downregulates the release of stress-related factors such as IL-6, TNF-α, and IL-1β; simultaneously activates AMPK signaling and inhibits mTOR pathway activity, reduces abnormal immune cell infiltration, adjusts cellular energy metabolism patterns, reduces abnormal mitochondrial production of reactive oxygen species, and alleviates local imbalances in tissues such as the skin, liver, and intestines.

3. Activate the PPARα pathway and regulate lipid metabolism in vivo: Upregulate the expression of PPARα, PGC1α, and CPT1α lipid oxidation-related genes, accelerating fatty acid decomposition and oxidation; inhibit SREBP1 and FASN lipid synthesis transcription factors, reducing lipid droplet accumulation; simultaneously regulate the gut microbiota-bile acid-FXR metabolic axis, promoting bile acid excretion, balancing lipid synthesis and decomposition, improving excessive lipid accumulation, and simultaneously increasing autophagy levels to clear lipid metabolic waste.

4. Regulate mitochondrial homeostasis and cell proliferation balance: Intervene in mitochondrial energy metabolism, reduce abnormal glycolysis activity, and balance the proportion of mitochondrial apoptosis-related proteins; downregulate the activity of pro-proliferation signaling axes such as PI3K/Akt and Wnt, limiting excessive cell proliferation; strengthen the autophagy pathway, clear damaged mitochondria, reduce the accumulation of abnormally metabolized cells, and maintain normal cell cycle homeostasis.

5. Regulating the Gut Microbiota and Bile Acid Metabolism Axis: Altering the gut microbiota structure, reducing the abundance of bile salt hydrolysate bacteria, and increasing the content of conjugated bile acids; inhibiting intestinal FXR signaling, downregulating FGF15 expression, regulating hepatic lipid metabolism through enterohepatic circulation, establishing a metabolic regulatory pathway between the gut and liver, and improving lipid metabolism disorders from an endogenous circulation level.

6. Interfering with Physiological Processes Related to Exogenous Microbial Replication: By binding to microbial proteases and transcription-related structures, interfering with microbial nucleic acid replication and protein assembly processes, and inhibiting microbial proliferation cycles, the system achieves a restraining effect on the growth activities of various exogenous microorganisms through natural molecular structures.
