The present invention provides compounds of Formula I:
wherein: R
1
is a label (e.g., a detectable groups; an anti-tumor agent)s; L is present or absent and when present is a linking group; and x represents an integer from 1 to 10; or a pharmaceutically acceptable salt thereof. the compounds are useful for, among other things, identifying cysteine sulfenic acids in proteins and monitoring oxidative damage in proteins and cells.
本发明提供了I式化合物:其中:R1是标签(例如,可检测的基团;抗肿瘤剂);L存在或不存在,当存在时是连接基团;x代表1到10的整数;或其药学上可接受的盐。该化合物可用于识别蛋白质中的半胱
氨酸磺
酚酸并监测蛋白质和细胞中的氧化损伤等方面。
