which play crucial roles in various critical physiological activities. To clarify their complex correlations in signal transduction and metabolism pathways, methods to distinguish H2S, cysteine (Cys), homocysteine (Hcy), and glutathione (GSH) at the same time are highly needed. Herein, we deliberately integrate 7-diethylcoumarin and resorufin through an ether bond to develop RC for simultaneous differentiation
生物硫醇是必需的反应性硫物质(RSS),在各种关键的生理活动中起关键作用。为了阐明它们在信号转导和代谢途径中的复杂相关性,迫切需要同时区分H 2 S,半胱氨酸(Cys),高半胱氨酸(Hcy)和谷胱甘肽(GSH)的方法。在此,我们有意通过醚键结合7- diethylcoumarin和试卤灵开发RC为半胱氨酸,同型半胱氨酸,谷胱甘肽,和H的同时分化2首次S上。RC响应H 2显示出不同的荧光颜色在水性培养基和活细胞中,S,Cys,Hcy和GSH分别为红色,蓝红色,蓝绿色红色和绿红色。这项工作不仅报道了一个健壮的分子RC,以解开生物系统中不同生物硫醇之间复杂的相互作用网络,而且还展示了一种设计用于同时感测各种RSS物种和其他生物物种的多信号荧光探针的策略。
