Resveratrol-3-O-sulfate is a bioactive metabolite that suppresses pro-inflammatory cytokine expression (e.g., IL-1β, TNF-α) in LPS-stimulated immune cells and exhibits antioxidant properties. It also inhibits proliferation and induces apoptosis in colorectal adenocarcinoma cells and binds to the mitochondrial target mitoNEET, indicating potential research applications in inflammation, oncology, and metabolic studies.
