A new dual-emission fluorescent probe 4-nitro-7-(4-(1-phenylimidazo [1,5-a]- pyridin-3-yl)phenoxy)benzo [c] (Yin et al., 2017; Jia et al., 2015; Chan et al., 2012) [1,2,5]oxadiazole (IP-NBD) with high sensitivity and selectivity for the detection of cysteine (Cys)/homocysteine (Hcy) and glutathione (GSH) was designed and synthesized. The probe, which exhibits low cytotoxicity and good cell penetration
新型双发射荧光探针4-硝基-7-(4-(1-苯基咪唑并[1,5- a ]-吡啶-3-基)苯氧基)苯并[c](Yin等,2017; Jia等等人,2015年; Chan等人,2012年)[1,2,5]恶二唑(IP-NBD)具有高灵敏度和高选择性,可检测半胱氨酸(Cys)/高半胱氨酸(Hcy)和谷胱甘肽(GSH)并合成。该探针具有低细胞毒性和良好的细胞穿透能力,可以快速检测Cys / Hcy,检测限低至140/180 nM,并已成功测试了细胞中Cys / Hcy和GSH。
