JP4-039 is a lead structure in a series of nitroxide conjugates that are capable of accumulating in mitochondria and scavenging reactive oxygen species (ROS). To explore structure–activity relationships (SAR), new analogs with variable nitroxide moieties were prepared. Furthermore, fluorophore-tagged analogs were synthesized and provided the opportunity for visualization in mitochondria. All analogs were tested for radioprotective and radiomitigative effects in 32Dcl3 cells.
JP4-039 是一系列硝基氧化物共轭物的先导结构,能够在线粒体中积累并清除活性氧(ROS)。为了探索结构-活性关系(
SAR),我们制备了具有可变亚硝基的新类似物。此外,还合成了荧光团标记的类似物,为线粒体中的可视化提供了机会。所有类似物都在 32Dcl3 细胞中进行了辐射防护和辐射诱变效应测试。
