Abstract
AbstractHepatitis and arthritis are prevalent inflammatory diseases, and the utilization of fluorogenic probes incorporating hydrogen sulfide (H2S) as a crucial mediator of inflammation presents significant opportunities for early detection. However, the poor in vivo biodistribution and limited targeted efficacy of molecule probes for inflammation imaging severely impede their ability to differentiate the extent of inflammation and provide real‐time monitoring of inflammatory levels. Therefore, we developed a highly efficient H2S‐activated near‐infrared (NIR) fluorogenic probe (hCy‐DNP) for real‐time tracking and capturing fluctuations in H2S levels within inflammatory lesions. hCy‐DNP demonstrates an exceptionally sensitive fluorescence response to H2S expression, enabling specific differentiation between various levels of lipopolysaccharide (LPS) ‐stimulated early hepatitis models in situ, while also facilitating visual monitoring for diagnosis and efficacy evaluation of arthritis. Therefore, hCy‐DNP offers an innovative tool for exploring early diagnosis and evaluating treatment effectiveness across diverse inflammatory diseases.
