Description

2-Mercapto-4(3H)-quinazolinone is a thiol-containing quinazolinone derivative. 2-Mercapto-4(3H)-quinazolinone was described in a study of the human purine nucleoside phosphorylase enzyme, where it was used to generate a binary complex with the enzyme to produce a crystal for structural study. 2-Mercapto-4(3H)-quinazolinone was also demonstrated to produce inhibition of xanthine oxidase which was used to monitor free radical scavenging properties of this and other compounds.
