Biological Activity

[Description]:

2,5-Dihydroxyacetophenone, isolated from Rehmanniae Radix Preparata, inhibits the production of inflammatory mediators in activated macrophages by blocking the ERK1/2 and NF-κB signaling pathways[1].

[Related Catalog]:

Research Areas >> Inflammation/Immunology

Signaling Pathways >> MAPK/ERK Pathway >> ERK

Signaling Pathways >> Stem Cell/Wnt >> ERK

[Target]

ERK1

ERK2

NF-κB

[In Vitro]

2,5-Dihydroxyacetophenone significantly inhibits NO production via the suppression of iNOS expression and significantly decreases levels of the pro-inflammatory cytokines TNF-α and IL-6 via the down-regulation of their mRNA expression in LPS-stimulated RAW264.7 cells. 2,5-Dihydroxyacetophenone potently inhibits the phosphorylation of extracellular signal-related kinase (ERK) 1/2 and the nuclear translocation of nuclear factor-κB (NF-κB) p65 in LPS-stimulated cells[1].
