Paeonol reduced lesions in LL-37-induced rosacea-like mice, correlating with suppressed S100A9-NF-κB signaling
Using network pharmacology to predict shared targets of paeonol and rosacea, then validating in an LL-37-induced rosacea-like BALB/c mouse model, the study found that 150 mg/kg paeonol markedly lowered redness area and score, reduced inflammatory cell and CD4+ T-cell infiltration and angiogenesis, and downregulated S100A9 and p65 phosphorylation, indicating its effects correlate with suppressed S100A9-NF-κB signaling.
