英文摘要：

OBJECTIVE To study the neuroprotection and brain targeting of scutellarin and its derivatives. METHODS The neuroprotection of scutellarin and its derivatives was evaluated by effecting the survival of rat cerebral cortical neurons cell in vitro. The blood brain barrier model by co- culturing brain capillary endothelial cells and astrocytes in vitro was established for the evaluation of their targeting on brain. RESULTS Both scutellarin and its derivatives had protected the brain neuron. And the penetration cross blood brain barrier of ethyl ester of scutellarin was better than scutellarin and its aglycone. CONCLUSION The ethyl ester of scutellarin can penetrate cross blood brain barrier and have brain targeting.
