  摘要：

  在二氯甲烷中对吩噻嗪和吩嗪进行臭氧处理时，检测到了阳离子自由基和臭氧阴离子自由基，而在对吩噁噻和噻蒽进行臭氧处理时，没有检测到这些自由基。溶剂的极性越大，底物的氧化电位越低，越有利于这些自由基的形成。在极性溶剂中，吩噻嗪和吩噁嗪的臭氧化可以用电子转移机制和亲电臭氧攻击来解释，而吩噁噻和噻蒽的臭氧化则只用亲电臭氧攻击来解释。

  Synthetic probes for detecting the activity of enzymes that catalyze reactions of post-translationally modified cysteine residues are described. The probes include “turn-on” probes that include a carbamate linkage that is cleaved via an intramolecular reaction with a free thiol produced by an enzyme catalyzed activity. The probes also include ratiometric, Michael addition-based probes that respond to enzymatic activity by a change in structure that results in a change in fluorescence properties. Methods of using the probes to detect enzymatic activity and disease are described. For example, the probes can be used to detect enzymatic activity in a variety of samples, including live cells and heterogeneous tissues. In addition, prodrugs that can be activated by enzymes that catalyze reactions of post-translationally modified cysteine residues and methods of using the prodrugs to treat disease are described.
