  摘要：

  Here, we investigated the structure-activity relationships of the 6,7-dimethoxyquinazoline moiety. With regard to exploration of positions and varieties of substituents on the quinazoline ring, 6,7-dialkoxy substitution was optimal. This study suggests the possibility of further modifications for this moiety. (C) 2003 Elsevier Ltd. All rights reserved.
