Astragalin is a natural flavonoid compound with strong antioxidant and anti-inflammatory activities and has shown potential therapeutic applications in various diseases, including cancer and cardiovascular diseases[1]. Astragalin is extracted from plants such as Mongolian milkvetch (Astragalus membranaceus) and sumac (Rhus chinensis)[2]. In cancer research, Astragalin has been reported to inhibit the proliferation of cancer cells and induce apoptosis[3]. Astragalin also protects the cardiovascular system by reducing oxidative stress and inflammation[4].
In vitro, Astragalin (0–100µM) treatment of human colorectal epithelial cells (HCT-116 and HT-29) significantly inhibited cell proliferation. Pre-treatment with Astragalin significantly reduced the mRNA expression levels of tumor necrosis factor-α (TNF-α)-induced interleukin-6 (IL-6), IL-8, and TNF-α. Additionally, Astragalin inhibited the phosphorylation and degradation of IκBα induced by TNF-α and reduced the DNA-binding activity of NF-κB[5]. Astragalin (1–20µM) treatment of human bronchial epithelial cells (BEAS-2B) significantly inhibited the epithelial-mesenchymal transition (EMT) process induced by oxidative stress. Astragalin restored the reduced expression of E-cadherin induced by H₂O₂ and dose-dependently inhibited the expression of vimentin and the formation of autophagosomes[6].
In vivo, Astragalin (10, 20, 40mg/kg) was administered via intraperitoneal injection to APP/PS1 transgenic mice once daily for one month. Astragalin significantly improved cognitive dysfunction in APP/PS1 mice. Astragalin also alleviated neuronal damage in the hippocampus, reduced amyloid-β (Aβ) deposition and the number of senile plaques, and activated autophagy by promoting the expression of autophagy-related proteins (LC3B, Beclin-1, ATG5, ATG12, and LAMP-1). Furthermore, Astragalin inhibited the phosphorylation levels of PI3K/Akt-mTOR signaling pathway-related proteins, thereby exerting neuroprotective effects[7]. Astragalin (5, 10mg/kg/day) was administered orally to streptozotocin (STZ)-induced diabetic mice for 4 weeks. Astragalin significantly improved proteinuria and reduced serum creatinine levels in diabetic mice. Astragalin also alleviated renal pathological damage. Astragalin significantly inhibited the activity of aldose reductase (ALR2) in the kidneys, reduced oxidative stress, improved mitochondrial dysfunction, promoted mitochondrial biogenesis, maintained mitochondrial dynamic balance, and reduced renal cell apoptosis by activating the AMPK-dependent PGC1α pathway[8].

| Cell experiment [1]: | |
Cell lines | BEAS-2B cells |
Preparation Method | BEAS-2B cells were seeded into 6-well plates at a density of 5 × 104 cells per well and cultured in HEPES-buffered M199 medium containing 10% FBS and other supplements for 24 hours. The cells were then pretreated with different concentrations (1, 5, 10, and 20μM) of Astragalin for 1 hour before being stimulated with 20μM H₂O₂ for up to 72 hours. |
Reaction Conditions | 1, 5, 10, and 20μM Astragalin; 20μM H₂O₂; 72 hours |
Applications | Astragalin significantly restored the expression of E-cadherin and inhibited the induction of vimentin in H₂O₂-treated BEAS-2B cells, indicating its ability to attenuate EMT. Astragalin blocked the induction of autophagy-related proteins beclin-1 and LC3A/B and reduced autophagosome formation. |
| Animal experiment [2]: | |
Animal models | C57BL/6J mice |
Preparation Method | Six-week-old male C57BL/6J mice were used. Diabetes was induced by intraperitoneal injection of streptozotocin (STZ, 100mg/kg/day) for two consecutive days. Seven days after injection, mice with random blood glucose ≥16.7mmol/L were randomly divided into groups and treated with Astragalin (5 and 10mg/kg/day) by oral gavage for 4 weeks. At the end of the experiment, blood and kidney tissues were collected for analysis. |
Dosage form | 5 and 10mg/kg/day for 4 weeks; p.o. |
Applications | Astragalin significantly improved renal function by reducing proteinuria, lowering serum creatinine levels, and improving kidney pathological damage in diabetic mice. It also inhibited aldose reductase activity, reduced oxidative stress, improved mitochondrial dysfunction, and regulated mitochondrial dynamics by activating the AMPK/PGC1α pathway. |
