Demethyleneberberine
Based on 3 publication(s) in Google Scholar
Demethyleneberberine is a blood-brain barrier-permeable antioxidant. Demethyleneberberine exerts antioxidant effects by targeting mitochondria, activates the AMPK signaling pathway to regulate lipid metabolism, and inhibits inflammation-related pathways such as NF-κB and MAPK. Demethyleneberberine can be used in the research of inflammatory and other diseases.

Activité biologique
Demethyleneberberine (50 μM; 2 h) neutralizes 55% of H2O2-induced ROS in HepG2 cells[1].
Demethyleneberberine (50 μM; 1 week) reverses ethanol-induced mitochondrial membrane potential depolarization in ethanol-exposed HepG2 cells[1].
Demethyleneberberine (0-50 μM; 0-24 h) shows no toxicity to HepG2 cells at concentrations up to 50 μM, reduces cellular lipid accumulation by 25% at 10 μM, and activates the AMPK pathway in a dose- and time-dependent manner[2].

Demethyleneberberine (40 mg/kg per day; i.p.; daily; 5 weeks) prevents chronic alcohol intake-induced liver injury and steatosis in ICR mice by inhibiting oxidative stress pathways and restoring fatty acid oxidation[1].
Demethyleneberberine (20-40 mg/kg; i.p.; daily administration; for 4 consecutive weeks) alleviates MCD-induced non-alcoholic fatty liver disease (NAFLD) in ICR mice and spontaneous NAFLD in db/db mice[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (7.71 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
