Abstract
Long-term inflammation will develop into chronic inflammation and become inflammatory diseases. Antibiotics are commonly used in clinical practice to treat inflammatory diseases. But patients are prone to drug resistance. So we need to find new treatment. Chlorogenic acid is an organic compound extracted from honeysuckle and other plants. Its anti-inflammatory activity is strong, and it has a significant anti-inflammatory effect on inflammatory diseases in various systems. It has been shown that chlorogenic acid can regulate inflammation-related signaling pathways, such as nuclear factor κB (NF-κB) canonical signaling pathway, NF-κB atypical signaling pathway, nuclear factor-erythroid 2-related factor 2 (Nrf2) canonical signaling pathway, and Nrf2 atypical signaling pathway, etc. It can up-regulate the expression of anti-inflammatory cytokines such as interleukin (IL)-4, IL-10, IL-13 and down-regulate the expression of pro-inflammatory cytokine such as IL-1β, IL-6, and IL-8. Although chlorogenic acid has a strong anti-inflammatory effect, but clinical trials and application still face many difficulties. In the future, the anti-inflammatory molecular mechanism of chlorogenic acid should be further studied to explore its clinical application value and improve new ideas for the treatment of inflammatory diseases.
