The present invention relates to a compound based on cyanine scaffold for diagnosing sepsis by selectively detecting glutathione. The compound based on cyanine scaffold according to the present invention has the advantages of maintaining its structure in intracellular environment and of reacting selectively to glutathione only among many amino acids containing thiol group (R—SH) such as cysteine, homocysteine, and glutathione, to produce changes in absorption or fluorescence spectrum, making the compound useful for the detection of in vivo glutathione in biosamples and also for the diagnosis of sepsis characteristically displaying the changes of glutathione concentration.
                            本发明涉及一种基于青蛉酮骨架的化合物,用于通过选择性检测
谷胱甘肽诊断败血症。根据本发明的基于青蛉酮骨架的化合物具有在细胞内环境中保持其结构的优点,并且在众多含
硫醇基团(R—SH)的
氨基酸中只对
谷胱甘肽选择性地发生反应,如半胱
氨酸、同型半胱
氨酸和
谷胱甘肽,从而产生吸收或荧光光谱的变化,使得该化合物在
生物样本中检测体内
谷胱甘肽以及诊断表现为
谷胱甘肽浓度变化的败血症具有用途。
