8-O-乙酰山栀苷甲酯具有抗脑缺血损伤的潜力，其对氧糖剥夺所致脑损伤的保护作用可能是通过抑制细胞内Ca2+升高和caspase-3活性而实现的。

8-O-Acetylshanzhiside methylester 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.

Treatment of SH-SY5Y cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) blocks TNF-α-induced nuclear transcription factor κB (NF-κB) activation and decreases high-mobility group box-1 (HMGB-1) expression. . Treatment of H9c2 cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) 9 μM blocks TNF-α-induced NF-κB phosphorylation by blocking High-mobility group box1 (HMGB1) expression.

Barlerin (8-O-Acetyl shanzhiside methyl ester) 40 mg/kg demonstrates significant neuroprotective effect even after delayed administration at 4 hr after I/R. Barlerin 40 mg/kg attenuates the histopathological damage, decreases brain swelling, inhibits NF-κB activation and reduces HMGB-1 expression in ischaemic brain tissue. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly promotes angiogenesis in the ischaemic brain and improves functional outcome after stroke. Barlerin also significantly increases vascularization compared with vehicle treatment. It increases the expression of VEGF, Ang1, phosphorylation of Tie2 and Akt VEGF. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly shortens capillary blood clotting time and reduces blood loss volume, but does not influence mice activated partial thromboplastin time, prothrombin time or thrombin time. It significantly prolongs euglobulin clot lysis time in hyperfibrinolysis mice.
