Ebselen is an organoselenium compound with antioxidant, anti-inflammatory, and potential neuroprotective properties. It mimics the activity of glutathione peroxidase, an important antioxidant enzyme, by scavenging reactive oxygen species (ROS) and reducing oxidative stress. Ebselen has been studied for various therapeutic applications, including as a treatment for neurological disorders, such as stroke and Alzheimer’s disease, and as a potential antiviral agent. It is also being explored for its ability to modulate immune responses and protect against tissue damage in inflammatory conditions.
