title: Thioglycolic acid and pyrazole derivatives of 4(3H)-quinazolinone: synthesis and antimicrobial evaluation.
abstract: New derivatives of 4(3H)-quinazolinone were synthesized and evaluated for their antibacterial and antifungal activity. The derivatives are: 3-Aryl-2-[3-aryl-1-(carboxymethylthio)-3-oxopropyl)]-4(3H)-quinazolinones 2a-f; 3-Aryl-2-(3-aryl-1H-pyrazol-5-yl)-4(3H)-quinazolinones 3a-f; 3-Aryl-2-(1,3-diaryl-1H-pyrazol-5-yl)-4(3H)-quinazolinones 4a-f; 3-Aryl-2-(3-aryl-1-thiocarbamoyl-1H-pyrazol-5-yl)-4(3H)-quinazolinones 5a-f; 3-Aryl-2-[3-aryl-1-(carboxymethylthio)-3-hydroxyiminopropyl)]-4(3H)- quinazolinones 6a-f; and 3-Aryl-2-[3-aryl-1-(carboxymethy- lthio)-3-thiocarbamoyliminopropyl)]-4(3H)-quinazolinones 7a-f. Some of the tested compounds showed activity comparable to that of the standard references used.
