Synthesis and antihyperglycemic activity of suitably functionalized 3H-quinazolin-4-ones☆
摘要:
A series of 2-sec-amino-3H-quinazolin-4-ones (4a-p) and 4-sec-amino-2-chloroquinazolines (5a-b) have been synthesized by nucleophilic substitution reaction of 2-chloro-4(3H)-quinazolones (3) and 2,4-dichloroquinazolines (2) with amines, respectively. Most of the synthesized compounds were evaluated for antihyperglycemic activity but only 4a,b,d,j,o displayed significant reduction in blood glucose level in streptozotocin and sucrose loaded rat models.
