Abstract
Two series of 2-phenyl-4(3H) quinazolinone derivatives have been synthesized. Most of the tested quinazolinone derivatives showed considerable potent anti-inflammatory and analgesic activity of superior GIT safety profile in experimental rats in comparing to indomethacin as reference drug. Compounds VIa, VIb were the most potent anti-inflammatory in experimental rats in comparing to indomethacin as reference drug. Docking study into COX-2 has been made for derivatives of anti-inflammatory activity.
