Combining network pharmacology， molecular docking， and experimental verification to investigate the anti-rheumatoid arthritis effect and mechanism of Baeckea frutescens leaves

Food Science and Human Wellness 2024年

作者： Xueyang Guo Mengyao Zhang Haixia cai xinyue jiang Siyuan Zhou Wen Gong Zijiao Wei Weili Qiao Beixi jia Department of Pharmacognosy， School of Pharmaceutical Science， Zhengzhou University Department of Pharmacy， Henan Provincial People's Hospital

The aromatic Baeckea frutescens leaves (BFL) known as “Gang-Song-Cha” is a popular drink (Tea) in South China. To explore the healthcare value， a systematic and in-depth study on BFL alleviating rheumatoid arthritis (RA) was carried out by integrating network pharmacology， molecular docking， and experimental verification. The efficacy was first evaluated， and the BFL extract could ameliorate RA by inhibiting articular swelling， lowering immune organ index， improving the ankle pathologies， and regulating serum levels of TNF-α， IL-6， and IL-10 in CIA rats. Then the anti-RA mechanism of BFL was investigated by leveraging the high-content and active component 5-hydroxy-7-methoxy-2-isopropylchromone (Chro.)， and the potential signaling pathway and related target proteins for Chro. acting on RA were analyzed by KEGG enrichment and docking simulation. Finally， the experimental validations were conducted on RA-FLS cells， and compound Chro. could inhibit cell invasion and migration， block cell cycle at G2/M phase and induce apoptosis， and reduce the secretion of inflammatory cytokines by suppressing the PI3K-Akt pathway. These results provided pharmacological basis for the folk usage of “Gang-Song-Cha (Tea)” for intervening RA.
