半胱氨酸组织蛋白酶是在病理生理过程中至关重要的蛋白酶,并显示出作为疾病和医疗状况的靶标或生物标志物的潜力。组织蛋白酶家族的 11 个成员在某些情况下是多余的,但又非常独立于其他成员,因此需要开发泛组织蛋白酶靶向工具以及对特定组织蛋白酶具有选择性且几乎没有脱靶活性的探针。本综述讨论了用于实现半胱氨酸组织蛋白酶靶标和所结合的成像模式之间的这种定制选择性的多种设计策略。通过简要强调一些著名的半胱氨酸组织蛋白酶的性质、它们与特定疾病的关系以及组织蛋白酶成像探针在从基础生化研究到临床应用的研究中的应用,我们对这些不同工具的威力进行了背景介绍。其中之一与其他蛋白不同:11 种半胱氨酸组织蛋白酶在病理学中具有重叠但不同的作用,分子探针使其能够在许多应用中进行累积或选择性检测。
Cysteine cathepsins are proteases critical in physiopathological processes and show potential as targets or biomarkers for diseases and medical conditions. The 11 members of the cathepsin family are redundant in some cases but remarkably independent of others, demanding the development of both pan-cathepsin targeting tools as well as probes that are selective for specific cathepsins with little off-target activity. This review addresses the diverse design strategies that have been employed to accomplish this tailored selectivity among cysteine cathepsin targets and the imaging modalities incorporated. The power of these diverse tools is contextualized by briefly highlighting the nature of a few prominent cysteine cathepsins, their involvement in select diseases, and the application of cathepsin imaging probes in research spanning basic biochemical studies to clinical applications. One of these is not like the others: The 11 cysteine cathepsins have overlapping but distinct roles in pathology, and molecular probes enable their cumulative or selective detection in many applications.
