Abstract
A series of new 3-substituted-4-(4-aminobutyl)-1,4-benzoxazepin-5(4H)-one derivatives (1-5) which showed a very high affinity for 5-HT1A receptor with good selectivity over dopamine D2 receptor was synthesized. Among these compounds, 3-chloro-4-[4-[4-(2-pyridinyl)-1,2,3,6-tetrahydropyridin-1-yl]butyl]-1,4-benzoxazepin-5(4H)-one (5: SUN N4057) exhibited remarkable neuroprotective activity in a transient middle cerebral artery occlusion (t-MCAO) model.
