2,5-二氯对苯二醌, 2,5-Dichloro-1,4-benzoquinone

2,5-Dichloro-1,4-benzoquinone is a chlorine compound that belongs to the class of quinones. It has been shown to be an irreversible inhibitor of bacterial DNA gyrase and topoisomerase IV. 2,5-Dichloro-1,4-benzoquinone is a model system for studying the quantum theory of light. The hydroxyl group on its molecule can form strong hydrogen bonds with water molecules in the active site of bacterial DNA gyrase and topoisomerase IV. X-Ray diffraction data shows that 2,5-dichloro-1,4-benzoquinone binds to the enzyme's acyl chain region and inhibits its ability to synthesize DNA. The kinetic studies show that 2,5-dichloro-1,4-benzoquinone is an effective inhibitor of DNA synthesis by interfering with the process of oxidative deamination.
