  Discovery and structure–activity relationships of a novel class of quinazoline glucokinase activators

  摘要：

  We describe design, syntheses and structure-activity relationships of a novel class of 4,6-disubstituted quinazoline glucokinase activators. Prototype quinazoline leads (4 and 5) were designed based on the X-ray analyses of the previous 2-aminobenzamide lead classes. Modifications of the quinazoline leads led to the identification of a potent GK activator (21d). (C) 2009 Elsevier Ltd. All rights reserved.
