Endoplasmic reticulum-targeted fluorescent probe with aggregation-induced emission features for imaging peroxynitrite in drug-induced liver injury model. Biosens Bioelectron 2024; 262:116573. [PMID: 39018976 DOI: 10.1016/j.bios.2024.116573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 05/17/2024] [Accepted: 07/12/2024] [Indexed: 07/19/2024]
Abstract
Drug-induced liver injury (DILI) poses a severe threat to public health. Endoplasmic reticulum (ER) stress contributes significantly to DILI pathogenesis, with peroxynitrite (ONOO-) identified as a pivotal indicator. However, the temporal and spatial fluctuations of ONOO- associated with ER stress in the pathogenesis of DILI remain unclear. Herein, a novel ER-specific near-infrared (NIR) probe (QM-ONOO) with aggregation-induced emission (AIE) features for monitoring ONOO- fluctuations in DILI was elaborately constructed. QM-ONOO exhibited excellent ER-targeting specificity, a large Stoke's shift, and a low detection limit (26.9 nM) toward ONOO-. QM-ONOO performed well in imaging both exogenous and endogenous ONOO- in HepG2 cells. Furthermore, molecular docking calculations validated the ER-targeting mechanism of QM-ONOO. Most importantly, using this probe allowed us to intuitively observe the dynamic fluctuations of ONOO- during the formation and remediation processes of DILI in the acetaminophen (APAP)-induced mouse model. Consequently, this work provides a promising tool for in-depth research of ONOO- associated pathological processes in DILI.

Abstract
We report a specific lysosome targeted light-responsive CO-releasing molecule (Lyso-CORM). Lyso-CORM is very stable under dark conditions. CO and singlet oxygen (1O2) generation was effectively triggered under one photon and two photon excitation (800 nm) conditions. The cytotoxicity results demonstrated that Lyso-CORM showed good phototoxicity due to the synergistic effect of CO and 1O2 release, and its good biocompatibility, negligible dark toxicity and specific lysosome targeting make Lyso-CORM a potent candidate for phototherapeutic applications.
