Quinazolinone is a heterocyclic chemical compound. There are two structural isomers, 2-quinazolinone and 4-quinazolinone, with the 4-isomer being the more common.

  • 2-Quinazolinone

  • 4-Quinazolinone

Derivatives

Jafari et al.[1] state that "One of the most important [groups of] heterocycles in medicinal chemistry are quinazolines[,] possessing [a] wide spectrum of biological properties like antibacterial, antifungal, anticonvulsant, anti-inflammatory, anti-HIV, anticancerous and analgesic activities. This skeleton is an important pharmacophore considered as a privileged structure."[1] Their review discusses quinazolines and quinazolinone derivatives with antimicrobial and cytotoxic activities.[1]

Quinazolinone drugs function as hypnotic/sedatives that contain a 4-quinazolinone core. Their use has also been proposed in the treatment of cancer.[2]
