nitroxyl radical (nitroxide) ligands were used to detect amyloid-β fibrils, the main constituents of senile plaques in Alzheimer's disease, using anisotropic ESR spectra, and were found to affect the aggregation process due to the radical functionality. These compounds have great potential as novel and multifunctional probes, combining spin labels, spin probes, and fluorescence probes.
研究人员利用各向异性 ESR 光谱将淀粉样亚硝基自由基(亚硝基)配体用于检测淀粉样δ纤维(阿尔茨海默病老年斑的主要成分),并发现自由基功能会影响淀粉样δ纤维的聚集过程。这些化合物结合了自旋标签、自旋探针和荧光探针,具有作为新型多功能探针的巨大潜力。
