Description:

Wogonoside has anticoagulant, anti-inflammatory, anti-angiogenic and anticancer effects, it may exert its anti-inflammatory effect via dual inhibition of NF-κB and NLRP3 inflammasome. Wogonoside induced autophagy through the MAPK-mTOR pathway, it inhibited LTB 4 production at the concentration of 100 uM.

Wogonoside inhibits lipopolysaccharide-induced angiogenesis in vitro and in vivo via toll-like receptor 4 signal transduction.    

Wogonoside, one flavonoid derived from the root of Scutellaria baicalensis Georgi, has been reported for its anti-inflammation activity; however, whether it can inhibit inflammation-induced angiogenesis is still unclear. 

METHODS AND RESULTS:

In the present study, we evaluated the effect of Wogonoside on lipopolysaccharide (LPS)-induced angiogenesis in vitro and in vivo. Wogonoside suppressed the LPS-stimulated migration and tube formation of human umbilical vein endothelial cells (HUVECs), as well as microvessel sprouting from rat aortic rings in vitro. Moreover, Wogonoside also inhibited LPS-stimulated vessel growth of Chicken chorioallantoic membrane (CAM) in vivo. The mechanism revealed that Wogonoside inhibited LPS-induced toll-like receptor 4 (TLR4) up-regulation and its downstream mitogen-activated protein kinases (MAPKs) activation, by decreasing the phosphorylation of c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase. 

CONCLUSIONS:

The results suggest that Wogonoside inhibits LPS-induced angiogenesis both in vitro and in vivo, and that it might have a therapeutic potential for the diseases associated with the development of both inflammation and angiogenesis progress.

Wogonoside induces autophagy in MDA-MB-231 cells by regulating MAPK-mTOR pathway.    

Previous studies have demonstrated that Wogonoside, a bioactive flavonoid extracted from the root of Scutellaria baicalensis Gerogi, has anti-inflammatory and anti-angiogenic activities. 

METHODS AND RESULTS:

In this study, we evaluated Wogonoside-induced autophagy on human breast MDA-MB-231 cells. We report that Wogonoside triggered the formation of microtubule-associated protein-light chain 3 (MAP-LC3) positive autophagosomes and the accumulation of acidic vesicular and autolysosomes in MDA-MB-231 cells. In addition, cells treated by Wogonoside developed autophagosome-like characteristics, including single and double membrane vacuoles containing intact and degraded cellular debris. The results showed that Wogonoside promotes the expression of LC3-II and Beclin-1. Furthermore, Wogonoside inhibited cell growth of MDA-MB-231 cells in a concentration- and time-dependent manner, which was associated with Wogonoside-induced autophagy. Wogonosidealso suppressed the activation of mammalian target of rapamycin (mTOR) and p70-S6 kinase (p70S6K) by regulating the expression of the extracellular signal-regulated kinase (ERK1/2) and p38 involved mitogen-activated protein kinase (MAPK) signaling pathway. 

CONCLUSIONS:

Taken together, these results suggest that Wogonoside partially inhibits MDA-MB-231 cell growth by inducing autophagy through the MAPK-mTOR pathway and may be a promising anti-tumor agent.

Wogonoside protects against dextran sulfate sodium-induced experimental colitis in mice by inhibiting NF-κB and NLRP3 inflammasome activation.    

Previous studies have demonstrated that Wogonoside, the glucuronide metabolite of wogonin, has anti-inflammatory, anti-angiogenic and anticancer effects. However, the anti-inflammatory mechanism of Wogonoside has not been fully elucidated. Recently, NLRP3 inflammasome has been reported to be correlated with inflammatory bowel disease for its ability to induce IL-1β release. Nevertheless, there are few drug candidates targeting NLRP3 inflammasome for this disease. 

METHODS AND RESULTS:

In this study, we investigated the anti-inflammatory effect of Wogonoside in dextran sulfate sodium (DSS)-induced murine colitis and further revealed the underlying mechanisms by targeting NF-κB and NLRP3 inflammasome. Wogonoside treatment dose-dependently attenuated DSS-induced body weight loss and colon length shortening. Moreover, Wogonoside prevented DSS-induced colonic pathological damage, remarkably inhibited inflammatory cells infiltration and significantly decreased myeloperoxidase (MPO) and inducible nitric oxide synthase (iNOS) activities. The production of pro-inflammatory mediators in serum and colon was also significantly reduced by Wogonoside. The underlying mechanisms for the protective effect of Wogonoside in DSS-induced colitis may be attributed to its inhibition on NF-κB and NLRP3 inflammasome activation in colons. Furthermore, Wogonoside markedly decreased production of IL-1β, TNF-α and IL-6 and suppressed mRNA expression of pro-IL-1β and NLRP3 in phorbol myristate acetate (PMA)-differentiated monocytic THP-1 cells via inhibiting the activation of NF-κB and NLRP3 inflammasome. 

CONCLUSIONS:

In conclusion, our study demonstrated that Wogonoside may exert its anti-inflammatory effect via dual inhibition of NF-κB and NLRP3 inflammasome, suggesting that Wogonoside might be a potential effective drug for inflammatory bowel diseases.
