PG - 13-19 LID - S0891-5849(20)32116-X [pii] LID - 10.1016/j.freeradbiomed.2020.12.443 [doi] AB - Nitric oxide donors (NODs) are indispensable in biological research and disease treatment. NODs had been utilized to treat cardiovascular diseases in clinic and many others are under trial. Thiols are typically required for these donors to release NO. Yet, their mechanism is complex and often lead to resistance. Herein, we reported that N-nitrosated electron-deficient dyes are capable of NO release with one-electron reduction. A fluorophore is generated simultaneously, whose fluorescence is harnessed to monitor the profile of NO release. Through electrochemical and spectral studies, NOD f3 was found to exhibit good biocompatibility and high reduction efficiency and its potentials in cell-protection in oxygen and glucose deprivation (OGD) models were showcased with endothelial cells. This work aims at offering a new approach to design reduction-triggered NOD, which have therapeutic potentials in ischemia-reperfusion. CI - Copyright (c) 2021 Elsevier Inc. All rights reserved.
