Emodin: A Promising Natural Compound for Combating Fibrotic Diseases

Fibrotic diseases place a substantial burden on health and the economy, with limited treatment options. Therefore, effective therapeutic strategies are urgently needed. Emodin, a natural compound with diverse biological activities, has been demonstrated in multiple studies over recent years to have potential therapeutic effects on fibrotic diseases. This review aims to provide a comprehensive overview of the existing research on emodin's pharmacological effects and mechanisms in inhibiting fibrotic disease, with a focus on its therapeutic advantages and systemic mechanisms. Recent studies have shown that emodin plays a role in combating fibrotic diseases by suppressing the production of inflammatory cytokines, such as IL-1β, IL-6, and TNF-α; it alleviates inflammation by inhibiting the NF-κB signaling pathway and preventing the degradation of IκB. Emodin also suppresses the activation of the MAPK pathway, enhances the expression of antioxidant enzymes, and influences the metabolism of the extracellular matrix (ECM). Thus, emodin is highlighted for its potential as an antifibrotic agent, and future research directions are proposed to deepen our understanding and develop novel treatment strategies for fibrotic diseases.
