Norkurarinol is a prenylated flavonoid with significant anti-rotavirus properties. Isolated from Sophora flavescens, it effectively inhibits mushroom tyrosinase DOPA oxidase activity, exhibiting an IC50 of 2.1 μM. Norkurarinol also suppresses poly(I:C)-induced NF-κB and AP-1 activation, while decreasing levels of pro-inflammatory cytokines such as TNF-α and IL-6. Furthermore, it inhibits the phosphorylation of key mitogen-activated protein kinases (p38, JNK, and ERK1/2) and promotes IRF3 phosphorylation, highlighting its potential in antiviral and anti-inflammatory research applications.
