Icaritin, a metabolite of Icarrin, Alleviates non-alcoholic fatty liver disease via inhibition of lipogenesis and ER stress
Eur J Pharmacol. 2022 Nov 10:175378. doi: 10.1016/j.ejphar.2022.175378. Online ahead of print.ABSTRACTNon-alcoholic fatty liver disease (NAFLD) is one of the most serious global public health concerns. However, there are currently no effective drugs for treatment of this disease. Icariin (ICA), a small-molecule natural product extracted from Epimedium brevicornu Maxim, offers various pharmacological activities. In the present work, we wondered whether ICA can attenuate NAFLD in db/db mice treated with ICA for 8 weeks and how ICA exert an influence on NAFLD. In db/db mice, ICA treatment had a robust effect on inhibition of ...

Icariside II induces rapid phosphorylation of endothelial nitric oxide synthase via multiple signaling pathways
In this study, human umbilical vein endothelial cells (HUVECs) were stimulated with Icariside II in the presence or absence of multiple inhibitors (1 µM), including LY294002 (PI3K-inhibitor), MK-2206 (AKT-inhibitor), Bisindolylmaleimide X (AMPK-inhibitor), H-89 (CaMKII-inhibitor), KN-62 (PKA-inhibitor), Dorsomorphin (PKC-inhibitor). The proliferation of HUVECs was assessed using cell counting kit-8 (CCK-8). The release of nitric oxide (NO) within HUVECs was detected via fluorescence probe (DAF-FM). Western blot was used to examine the effect of Icariside II on the expression of eNOS, phosphorylation of eNOS, and common si...

Immunostimulatory activity and structure-activity relationship of epimedin B from Epimedium brevicornu Maxim.
Epimedii Folium (EF, Epimedium brevicornu Maxim.), a traditional botanical drug, is famous for treating bone fractures, joint diseases, and several chronic illnesses. However, some studies indicated that EF could induce idiosyncratic drug-induced liver injury (IDILI) in the clinic. The NLRP3 inflammasome plays a crucial role in the pathogenesis of various human diseases, including IDILI. In the present study, we showed that epimedin B could specifically facilitate nigericin- or ATP-induced NLRP3 inflammasome activation under synergistic induction of mitochondrial reactive oxygen species. Moreover, epimedin B resulted in ac...

Epimedium brevicornum Maxim. Extract exhibits pigmentation by melanin biosynthesis and melanosome biogenesis/transfer
Epimedium brevicornum Maxim. (Epimedii Folium) is a traditional medicine widely utilized in China for sexual dysfunction and osteoporosis treatment. Recently, studies have reported that Epimedium flavonoid icariin displayed hair growth and melanogenic ability by targeting tyrosinase activity. Nevertheless, icariin hydrolysate icariside II and icaritin cause depigmentation due to their tyrosinase inhibition. These pigment functional discrepancies from Epimedium constituents arouse our great interest. Then, this study focused on the pigmentation effects of Epimedii Folium extract (EFE) on melanin synthesis and melanosome bio...

Epimedokoreanin B inhibits the growth of lung cancer cells through endoplasmic reticulum stress-mediated paraptosis accompanied by autophagosome accumulation
Chem Biol Interact. 2022 Aug 23:110125. doi: 10.1016/j.cbi.2022.110125. Online ahead of print.ABSTRACTEpimedokoreanin B (EKB) is a prenylated flavonoid isolated from Epimedium koreanum. In this article, we described the anti-cancerous effects of EKB and its underlying mechanism in human non-small cell lung cancer (NSCLC) A549 and NCI-H292 cells. EKB treatment inhibited cell proliferation and migration accompanied by cytoplasmic vacuolation in both cell lines. The cell death induced by EKB lacked the features of apoptosis like chromatin condensation, phosphatidyl serine exposure and caspase cleavage. The vacuoles stimulated...

Bioactive natural compounds as potential medications for osteogenic effects in a molecular docking approach
Bone defect repair and fracture healing are critical challenges in clinical treatments. Bioactive natural compounds are potential resources for medications for osteogenic effects. We have identified icariin, the effective ingredient of Epimedium pubescens, to promote osteogenic differentiation of bone mesenchymal stem cells (BMSCs) and repair bone defects. To explore more natural compounds with the potential modality for bone repair, in the present study, we employed an icariin-induced gene expression pattern as an osteogenic model and screened the Connectivity Map database for small molecules with gene expression signatur...
