Abstract:

Acetaminophen(APAP) is a drug used to treat headaches and fever symptoms, and its metabolites deplete glutathione(GSH) in the liver and cause oxidative stress. Taking large amounts of APAP in a short period of time can lead to liver failure. Yellow-emissive carbon dots(D-CDs) with strong antioxidant ability and good biocompatibility were synthesized by one-step hydrothermal method using catechol(CAT) and 2,5-dihydroxyterephthalic acid(DHTA) as precursors. In the APAP-induced zebrafish liver injury model, in vivo imaging showed that D-CDs could be effectively enriched in the zebrafish liver. The superoxide dismutase(SOD) activity and GSH content was increased and the content of malondialdehyde(MDA) was reduced, which finally effectively improved APAP- induced oxidative stress injury in zebrafish.
