Submit ReviewMethoxyluteolin
Description: Inhibitor of pro-inflammatory mediator release from mast cells
Chemical Name: 2-(3,4-Dimethoxyphenyl)-5,7-dimethoxy-4H-1-benzopyran-4-one
Purity: ≥98% (HPLC)
Biological Activity for Methoxyluteolin
Methoxyluteolin inhibits release of pro-inflammatory mediators from mast cells and decreases gene expression and release of TNF, VEGF and IL-8/CXCL8. The product also significantly inhibits IL-33 stimulated expression and release of CCL5 and CCL2. Methoxyluteolin pretreatment of LAD2 mast cells decreases gene expression of TNF, CXCL8 and VEGF in response to neurotensin or substance P via mTOR activation.

Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
