摘要：

The goal of this study was to estimate the blood brain barrier (BBB) permeability of Ginkgolide B in normal condition and models of ischemia both in vivo and in vitro. A sensitive LC-MS/MS analytical method was developed to determinate accurately the concentration of Ginkgolide B in cell, plasma and brain tissue. The injured rat brain microvessel endothelial cells (RBMECs) induced by Na2S2O4 served as a hypoxia/reoxygenation model in vitro. Intracellular concentration of Ginkgolide B increased in injured cells in a concentration-dependent manner. As a model of in vivo-ischemia/reperfusion, we performed middle cerebral artery occlusion (MCAC)in rats. Concentration of Ginkgolide B in the brain tissues showed higher in cerebral ischemia-reperfused animals than that in normal rats. To evaluate potential clinical effect of Ginkgolide B, we determined therapeutic time window in MCAO rats. Up to i.v. administration at 2 h after reperfusion of rats, Ginkgolide B Could decrease infarction volume and brain edema, exerting significant protective effect in cerebral ischemia injury. In conclusion, Ginkgolide B could pass through BBB, especially after ischemia-reperfusion injury of brain, and might be therapeutically effective for ischemia/reperfusion injury of human brain.
