半胱氨酸(Cys)、同型半胱氨酸(Hcy)和谷胱甘肽(GSH)等生物硫醇在维持生物系统的氧化还原稳态中起着至关重要的作用。这篇小综述总结了目前在生物医学研究和诊断领域中硫醇反应性探针面临的最重大挑战,强调了化学家在选择性探针和传感器领域中研究不足的需求和机会。多结合位点探针区分半胱氨酸,同型半胱氨酸,谷胱甘肽的进展突出作为一个创造性的新方向,在该领域,可以实现同步,准确的比率监测。新的探针设计策略和研究人员的优先事项可以更好地帮助解决当前的挑战,包括监测疾病状态,如自闭症和涉及氧化应激的慢性疾病,其特征是GSH,Cys和Hcy水平不同。
Biothiols such as cysteine (Cys), homocysteine (Hcy), and glutathione (GSH) play crucial roles in maintaining redox homeostasis in bio-logical systems. This Minireview summarizes the most significant current challenges in the field of thiol-reactive probes for biomedical research and diagnostics, emphasizing the needs and opportunities that have been under-investigated by chemists in the selective probe and sensor field. Progress on multiple binding site probes to distinguish Cys, Hcy, and GSH is highlighted as a creative new direction in the field that can enable simultaneous, accurate ratiometric monitoring. New probe design strategies and researcher priorities can better help address current challenges, including the monitoring of disease states such as autism and chronic diseases involving oxidative stress that are characterized by divergent levels of GSH, Cys, and Hcy.
