Abstract: Cardiovascular diseases currently dominate the cause of death worldwide. Oxidative stress injury is one of the important pathogenesis of cardiovascular diseases. The purpose of this study is to investigate the antioxidative protection effect of molybdenum disulfide (MoS2) nanoparticles on cardiomyocytes under oxidative stress injury. We synthesized MoS2 nanoparticles with antioxidant-like enzyme activity by a one-step hydrothermal method. MTT, intracellular apoptosis, intracellular reactive oxygen species (ROS) detection, and Western Blot experiments confirm that MoS2 nanoparticles (100 μg/mL) can protect H9c2 cardiomyocytes from oxidative stress injury induced by hydrogen peroxide (H2O2). At the same time, it also promotes the proliferation of H9c2 cardiomyocytes. This study shows that MoS2 nanoparticles can be used to construct antioxidant defense against cardiovascular diseases caused by oxidative stress injury, and provide experimental data and theoretical basis for the development of nanomedicine in the resistance to myocardial oxidative damage.

Key words: molybdenum disulfide nanoparticles, antioxidant enzyme-like activity, oxidative stress, reactive oxygen species, myocardial protection
