Time-Gated Luminescence Detection of Enzymatically Produced Hydrogen Sulfide: Design, Synthesis, and Application of a Lanthanide-Based Probe.

硫化氢（H2S）是参与多种生理与病理过程的重要气体信使，其代谢异常与高血压、睡眠呼吸暂停、急性胰腺炎及多种癌症相关。本文报道了一种用于时间门控发光检测H2S的镧系生物探针LP2-Cu(II)-Ln(III)（Ln=Tb或Eu）的设计、合成与应用。该探针为异双核金属配合物，由DO3A螯合的Tb(III)或Eu(III)、天线色团cs1...
