芥子气是一种强效起泡剂,也是最有害的化学战剂之一。为了解芥子气的毒代动力学和生物分布,建立一种可靠的芥子气监测方法是必不可少的。设计、合成了一种灵敏、选择性强的荧光探针,用于硫芥的检测。荧光发射强度与SM浓度呈良好的线性关系。应用SM-Flu探针对蓝水母和活细胞中的硫芥进行了检测和成像。使用SM-Flu,首先测量暴露于SM后小鼠脑中SM的浓度和时间曲线。
Sulfur mustard is a potent blister agent and one of the most harmful chemical warfare agents. To explore the toxicokinetics and biodistribution of SM, a reliable detection method for monitoring sulfur mustard would be indispensable. We describe the design, synthesis and application of a selective and sensitive turn-on fluorescent probe for sulfur mustard detection. A good linear relationship between fluorescence emission intensity and SM concentration was observed. The probe, SM-Flu, was applied to the determination and imaging of sulfur mustard in living cells andAurelia coeruleapolyps. With SM-Flu, concentration and time profiles for SM in mouse brain after exposure to SM were first measured.
