摘要:
A series of 3-[(4-arylpiperaz-1-yl)alkylamino]-2H-1,4-benzoxazines were prepared and their affinities for cloned human D-2, D-3, and D-4 dopamine receptor subtypes were measured. This led to the identification of 1a, 1f, and 1g as high affinity selective antagonists at the D-4 receptor. (C) 1997 Elsevier Science Ltd.
