Isorhapontigenin, a naturally-occurring stilbene derivative, exhibits potent antioxidant and anti-inflammatory properties [1]. Isorhapontigenin inhibits the EGFR-mediated pathways, including the ERK1/2 and PI3K/Akt signaling pathways, and regulates the activities of transcription factors such as FOXO1, STAT1, and Sp1[2]. Isorhapontigenin affects epigenetic regulation by altering the expression of microRNAs, particularly miR-137 and miR-145[2]. Isorhapontigenin has been widely used to inhibit Fe2+-Cys-induced malondialdehyde (MDA) generation in rat liver microsomes, brain mitochondria, and synaptosomes[3].
In vitro, Isorhapontigenin treatment for 24 hours significantly inhibited the release of IL-6 and CXCL8 in primary airway epithelial cells stimulated by 1ng/ml IL-1β + 50% cigarette smoke extract (CSE), with IC50 values of 17.3μM and 33.4μM, respectively[4]. Treatment with 100μM Isorhapontigenin for 24 hours significantly induced apoptosis in LNCaP and CWR22Rv1 cells, accompanied by nuclear fragmentation and cell rupture[5]. Treatment with 40μM Isorhapontigenin for 24 hours significantly reduced the expression level of HIF-1α protein in A549 cells and inhibited cell invasion[6].
In vivo, Isorhapontigenin treatment via intraperitoneal injection at a dose of 50mg/kg/day for 21 days significantly inhibited cardiac hypertrophy in the aortic-banded rat model, and decreased posterior wall thickness and left ventricle diastolic and systolic diameters [7]. Oral administration of Isorhapontigenin at a dose of 51.6mg/kg/day for 7 consecutive days prevented lipopolysaccharide (LPS)-induced acute lung injury in mice and reduced inflammatory response and oxidative stress[8].

| Cell experiment [1]: | |
Cell lines | LNCaP cells |
Preparation Method | LNCaP cells were grown in RPMI-1640 medium supplemented with 1% penicillin/streptomycin, and 10% heat-inactivated fetal bovine serum (FBS) at 37°C in an incubator with 5% CO2. LNCaP cells were cultured in 96-well plates in culture medium at 5000 cells/well. Different concentrations of Isorhapontigenin (0, 1, 10, 20, 50 and 100μM) were added and incubated at 37°C with 5% CO2 for 24h. Cell viability was measured. |
Reaction Conditions | 0, 1, 10, 20, 50 and 100μM; 24h |
Applications | Isorhapontigenin treatment significantly reduced cell viability of LNCaP cells in a dose-dependent manner. |
| Animal experiment [2]: | |
Animal models | Male C57BL/6 mice |
Preparation Method | Male C57BL/6 mice (6 weeks old) weighing 20-25g, were housed in an environmentally controlled room (12h light–dark cycle, 50%±10% relative humidity) at 23±2°C at a facility with free access to food and water. The mice (n = 60) were randomly divided into six groups. (1) Control group (n=10): sterile water via intraperitoneal injection 12h before sacrifice; (2) LPS + Isorhapontigenin group: oral administration with Isorhapontigenin (51.6mg/kg) daily for 7 days, and after 1h of the last administration, the mice were intraperitoneally injected with LPS (15mg/kg) and euthanized after 12h. The lung tissues of mice were fixed and embedded in paraffin, and the sections were stained with hematoxylin and eosin. |
Dosage form | 51.6mg/kg/day for 7 days; p.o. |
Applications | Isorhapontigenin treatment reduced LPS-induced acute lung injury and decreased inflammatory cell infiltration in mice. |
