Picroside II
Based on 4 publication(s) in Google Scholar
Picroside II is an antioxidant with oral activity that can reduce the production of ROS and protect the blood-brain barrier (BBB) after CI/R injury, offering neuroprotective effects. Picroside II has antioxidant, immune-regulating, antiviral properties, and inhibits apoptosis. Picroside II alleviates the inflammatory response in sepsis by suppressing the activation of the NLRP3 inflammasome and NF-κB pathways.
