Аннотация: Previously, we created a modular nanotransporter (MNT) containing a monobody to Keap1, an intracellular protein inhibitor of the Nrf2 transcription factor that controls cellular protection from oxidative stress and is capable of interacting with Keap1 in hepatocytes and protect these cells from the effects of hydro- gen peroxide. Oxidative liver damage by acetaminophen was used as a model to study the antitoxic effect of this MNT. Intraperitoneal injection of acetaminophen to mice resulted in an increase in the level of alanine aminotransferase and aspartate aminotransferase in the blood, as well as in liver edema. A significant decrease in the level of these enzymes in the blood, along with a decrease in liver edema, was observed after preliminary intravenous administration of MNT 2 h before the acetaminophen injection. The results obtained can be used as a basis for developing drugs to treat diseases associated with oxidative stress.
