  Coumarin derivatives protect against ischemic brain injury in rats

  摘要：

  Neuroprotection strategies are of great importance in the treatment of ischemic brain injury. Screening of our in-stock coumarin derivatives identified compound 1 as exhibiting neuroprotective activity. Subsequently, a structural optimization was carried out, which led to the discovery of the potent compound 20. This compound significantly attenuated the damage in a cell line derived from a pheochromocytoma of the rat adrenal medulla induced by oxygen glucose deprivation in vitro. Furthermore, compound 20 exhibited clear neuroprotection in middle cerebral artery occlusion rats by reducing infarct size and brain-water content, improving neurological function, and suppressing neuronal loss and neuropathological changes in the cortex and hippocampus. Pharmacokinetic evaluation indicated that compound 20 could penetrate the blood brain barrier of rats. (C) 2013 Elsevier Masson SAS. All rights reserved.
