The effect of 100 μM ibuprofen (IBU) on the content of reactive oxygen species and activity of antioxidant enzymes in 3- and 5-day-old wheat plants under normal growing conditions was analyzed. The growth parameters of these plants were also analyzed. The preparation was found to stimulate plant growth and cause a balanced accumulation of superoxide anion (O₂^-) and hydrogen peroxide (H₂O₂). This is accompanied by activation of superoxide dismutase (SOD) and catalase (CAT), enzymes involved in neutralization of reactive oxygen species (ROS). For the first time, the obtained results indicate the ability of the drug to regulate the state of redox metabolism and provide grounds for considering IBU as a plant antioxidant.
