一般描述
二醌是一种有机氧化剂，属于1,4-苯醌类，用于氧化还原流动Li–O2电池。
应用
- 杜醌在光合作用研究中的作用：一项对紫色细菌光合反应中心的研究表明，当杜醌被纳入QA结合位点时，会影响同位素编辑的FTIR差光谱，这对理解光合作用中的能量转换过程至关重要（Zhao et al., 2013）。
- 杜醌作为分子离子源的研究：研究表明，杜醌可以产生分子负离子，在质谱研究分子电离和寿命方面具有潜力（Khvostenko et al., 2012）。
- 杜醌在生化传感器中的应用：利用光系统II单层优化金电极表面的研究表明，杜醌在增强传感器响应方面起着关键作用，适用于生化传感器技术（Maly et al., 2005）。
- 杜醌类同系物的细胞毒性研究一项对包括杜罗醌在内的14种对苯醌同系物的比较研究，使用定量结构-毒性关系来评估大鼠肝细胞和PC12细胞的细胞毒性，适用于化学生产中的安全性评估（Siraki et al., 2004）。

How the ductus arteriosus (DA) closes at birth remains unclear. Inhibition of O2-sensitive K+ channels may initiate the closure but the sensor mechanism is unknown. We hypothesized that changes in endogenous H2O2 could act as this sensor. Using chemiluminescence measurements

The study objective was to use pulmonary arterial endothelial cells to examine kinetics and mechanisms contributing to the disposition of the quinone 2,3,5,6-tetramethyl-1,4-benzoquinone (duroquinone, DQ) observed during passage through the pulmonary circulation. The approach was to add DQ, durohydroquinone (DQH2)
