包括一氧化氮(NO)、一氧化碳(CO)和硫化氢(H2S)在内的内源性气体信号分子已被证明具有重要的生理和药理功能,并与生物系统中的多种疾病有关。为了更深入地了解它们的作用和作用机制,需要开发新的技术来有效地检测气体信号分子。小分子荧光探针由于其非侵入性、高选择性和实时原位检测能力,已被证明是一种检测和成像生物信使的有力方法。基于气体信号分子的固有特性,已经构建了许多荧光探针来满足各种需求。在这方面,我们总结了用于检测NO、CO和H2S的荧光探针领域的最新进展,并举例说明了这些探针的设计策略和应用实例。此外,我们还强调了气体发射器响应荧光探针的挑战和发展方向,希望为未来的研究提供一般性的启示。
Endogenous gaseous signaling molecules including nitric oxide (NO), carbon monoxide (CO) and hydrogen sulfide (H2S) have been demonstrated to perform significant physiological and pharmacological functions and are associated with various diseases in biological systems. In order to obtain a deeper insight into their roles and mechanisms of action, it is desirable to develop novel techniques for effectively detecting gaseous signaling molecules. Small-molecule fluorescent probes have been proven to be a powerful approach for the detection and imaging of biological messengers by virtue of their non-invasiveness, high selectivity, and real-time in situ detection capability. Based on the intrinsic properties of gaseous signaling molecules, numerous fluorescent probes have been constructed to satisfy various demands. In this perspective, we summarize the recent advances in the field of fluorescent probes for the detection of NO, CO and H2S and illustrate the design strategies and application examples of these probes. Moreover, we also emphasize the challenges and development directions of gasotransmitter-responsive fluorescent probes, hoping to provide a general implication for future research.
