Kaempferol 3-O-sophoroside
Based on 1 Customer Validation
Kaempferol 3-O-sophoroside is an orally active derivative of Kaempferol. It exhibits anti-inflammatory, analgesic, and antidepressant effects. Kaempferol 3-O-sophoroside is an inhibitor of the cell surface receptor toll-like receptor (TLR) 2/4 for High mobility group box 1 (HMGB1), and it also exerts anti-inflammatory effects by blocking the activation of NF-κB expression and the production of TNF-α. Kaempferol 3-O-sophoroside promotes the production of brain-derived neurotrophic factor (BDNF) and enhances autophagy by binding to AMP-activated protein kinase (AMPK), thereby exerting antidepressant effects. Kaempferol 3-O-sophoroside holds promise for research in the fields of inflammation and neurodegenerative diseases.

Kaempferol 3-O-sophoroside (5 μM, 48 h) does not affect the cell viability of human umbilical vein endothelial cells (HUVECs)[1]. Kaempferol 3-O-sophoroside (0-5 μM, 3 h) dose-dependently reduces barrier disruption in lipopolysaccharide (HY-D1056)-stimulated human umbilical vein endothelial cells (HUVECs), while it does not alter the integrity of the cell barrier when used alone[1]. Kaempferol 3-O-sophoroside (0-5 μM, 24 h) inhibits neutrophil adhesion to lipopolysaccharide (HY-D1056)-stimulated human umbilical vein endothelial cells (HUVECs) and suppresses neutrophil migration to HUVECs by blocking the activation of NF-κB and the production of TNF-α[1].

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 40% PEG300 5% Tween-80 45% Saline
