Barlerin (Standard) is a reference standard for research and analysis in studies involving Barlerin. Barlerin (8-O-Acetylshanzhiside methyl ester) has potential against cerebral ischemic injury, and its protective effect on oxygen-glucose deprivation-induced injury might be due to the suppression of intracellular Ca2+ elevation and caspase-3 activity, and improvement of mitochondrial energy metabolism.8-O-Acetylshanzhiside methylester can increase angiogenesis and improve functional recovery after stroke.8-O-Acetylshanzhiside methylester has protective effects on experimental myocardial ischemia injury, the effects might be due to block of myocardial inflammatory cascades through an HMGB1-dependent NF-κB signaling pathway.8-O-Acetylshanzhiside methylester protects diabetic brain against I/R injury by alleviating diabetic cerebral I/R injury and attenuating blood–brain barrier (BBB) breakdown, and its protective effects may involve HMGB-1 and NF-κB signalling pathway.
