Scutellaria baicalensis Georgi: A Promising Source of Bioactive Molecules for Kidney Disease Therapy

The incidence of kidney diseases has been increasing due to changes in modern lifestyles and the ecological environment. The progression of kidney disease is characterized by ongoing renal damage and a gradual decline in renal function, ultimately leading to end-stage renal disease. The limitations of present medications have brought many disadvantages to patients. Consequently, identifying bioactive molecules has emerged as a critical strategy in the development of novel therapies for kidney diseases, particularly those derived from natural medicinal resources. This review presents a comprehensive analysis of renoprotective effects and underlying mechanisms of the medicinal plant Scutellaria baicalensis Georgi based on evidence retrieved from multiple databases, including Web of Science, PubMed, and CNKI. Flavonoids from S. baicalensis have been demonstrated to have good renoprotective properties by mitigating inflammation and oxidative stress, inhibiting cell apoptosis, reducing renal fibrosis, etc. Baicalein, wogonin, baicalin, and wogonoside are considered as the main bioactive components of the renoprotective effect of S. baicalensis. Further research on candidate molecules derived from S. baicalensis represents a promising strategy for the development of novel therapeutic agents targeting kidney diseases.
