Activity-based probe compounds for use in labeling a cysteine protease are provided. The compounds are targeted to the protease through a specific targeting element. The compounds additionally include a detectable element, such as a fluorescent label, a radiolabel, or a chelator. In some cases, the compounds additionally include a quenching element that is released upon reaction with the protease. Also provided are compositions comprising the compounds and methods for using the compounds, for example in labeling a protease in an animal and in visualizing a tumor in an animal.
提供了用于标记半胱氨酸蛋白酶的基于活性的探针化合物。这些化合物通过特定的靶向元件靶向蛋白酶。化合物还包括可检测元素,如荧光标签、放射性标签或螯合剂。在某些情况下,化合物还包括一种淬灭元素,在与蛋白酶反应时释放出来。此外,还提供了包含这些化合物的组合物和使用这些化合物的方法,例如标记动物体内的蛋白酶和观察动物体内的肿瘤。
