Ebselen is a small molecule mimic and inducer of glutathione peroxidase activity and possesses antioxidant and anti-inflammatory properties. This drug has been investigated in phase II clinical trials for the treatment of Meniere's disease, bipolar disorder and in the prevention of hearing loss. Besides, experiments on mice have shown that ZIKV infection could be on the list for potential use of ebselen. It alleviates testicular pathology in mice with Zika virus infection and prevents its sexual transmission. Ebselen has various mechanisms of action. It binds to the N-terminal domain of soluble epoxide hydrolase and chemically reacts with the enzyme to quickly and irreversibly inhibit one of the enzymes' activity: phosphatase (Nterm-phos). Besides, ebselen inhibits inositol monophosphatase and thus exhibits lithium-like on human central nervous system (CNS) function. In addition, ebselen inhibits the G4 isoform of acetylcholinesterase. It is a well-known relationship between the cholinergic system and learning, memory and other common cognitive processes, thus ebselen can be studied for the treatment of memory impairment diseases.
