Abstract

Objective(s): Anemoside B4 (AB4) is a multifunctional compound with anti-inflammatory, anti-apoptotic, antioxidant, antiviral, and autophagy-enhancing effects. However, the role of AB4 in cerebral ischemia/reperfusion injury (CIRI) remains obscure. This experiment aims to investigate the pharmacological effects of AB4 in CIRI.
Materials and Methods: In vivo, eighty male SD rats were randomly divided into five groups: sham, MCAO/R, LD group (2.5 mg/kg), MD group (5 mg/kg), and HD group (10 mg/kg). The rats in sham and MCAO/R groups were given equal volumes of normal saline. In vitro, PC12 cells were divided into five groups: normal, OGD/R, OGD/R+AB4 (50 μM), OGD/R+AB4 (100 μM), and OGD/R+AB4 (200 μM). The cells were treated with hypoxia and hypoglycemia for 1.5 hr and reoxygenation for 24 hr.
Results: In vivo, TTC and neurological scoring tests indicated that AB4 favors promoting the recovery of the brain. The histopathologic study of the brain tissues revealed that AB4 inhibited the damage of neuron cells. The TUNEL assay found that AB4 could improve cell apoptosis and prevent the brain from injury. In vitro, the data showed that AB4 inhibited cell damage and prevented PC12 cells from OGD/R injury, reduced IL-1β content, and increased the IL-10 level. AB4 could inhibit apoptosis of PC12 cells, down-regulate Caspase 12 and BAX expression, and up-regulate Bcl-2 expression.
Conclusion: AB4 played a protective role in CIRI and could be a promising active ingredient against ischemia stroke.
