摘要

Schisandra chinensis (Turcz.) Baill (Sch) is a Traditional Chinese Medicinal (TCM) plant. It is divided into southern and northern. Sch is widely used in treating chronic kidney disease (CKD), which is primarily characterized by renal interstitial fibrosis. However, the knowledge of components in Sch that play a major role in treating renal fibrosis (RF) and its mechanism of action in vivo remains unclear. Here, the active ingredients of Sch for treating RF were initially identified through network pharmacological analysis and molecular docking technology. Cytological assays were conducted in vitro, and a gentamicin-induced zebrafish model was established to assess the anti-RF activity in vivo. Finally, the efficacy and mechanisms of these active components were further validated through transcriptomic analysis at the cellular level. Sch C has a stable combination (-8.69 kcal/mol) with Transforming Growth Factor Beta Receptor I (TGFBR1), which was identified as the main active ingredient of Sch in the treatment of RF. Transcriptomic and cell experiments revealed that Sch C inhibited the excessive accumulation of extracellular matrix (ECM) by regulating the TGF-β signaling pathway and PI3K-Akt signaling pathway, in which fibrosis markers CDH2 and α-SMA were significantly downregulated, and collagen expressions of COL3A1 and COL1A1 were reduced. In the zebrafish model, Sch C exhibited significant anti-fibrotic activity, suggesting its potential as a key anti-RF compound in Sch. This study significantly advances our understanding of the anti-fibrotic activity of Sch and elucidates its anti-RF mechanism. The findings provide a solid foundation for further research and development of effective anti-RF drugs derived from Sch.
