Parkinson's disease (PD) is a neurodegenerative disease that devastatingly affects people's lives. Numerous research studies have shown that peroxynitrite (ONOO-) plays a pivotal role in the pathogenesis of PD. However, a suitable tool that could quickly and sensitively detect ONOO- in various PD models is still lacking. To this end, we designed and synthesized a series of near-infrared probes that
帕金森氏病(PD)是一种严重影响人们生活的神经退行性疾病。大量研究表明,过氧亚硝酸盐(ONOO-)在PD的发病机理中起着关键作用。但是,仍然缺少能够在各种PD模型中快速灵敏地检测ONOO-的合适工具。为此,我们设计并合成了一系列近红外探针,这些探针可以通过近红外荧光成像以超快速且高度选择性的方式在几秒钟内检测ONOO-。值得注意的是,其中一种开发的探针NIR-PN1具有出色的传感性能和血脑屏障穿透能力。NIR-PN1已成功应用于多种PD模型中的ONOO通量成像,包括PC12细胞,果蝇,秀丽隐杆线虫和小鼠大脑,
