Ebselen

Category	Human immunodeficiency Virus (HIV)
CAS	60940-34-3
Description	Ebselen, also known as SPI-1005, is an organoselenium compound with potential anti-oxidant, anti-inflammatory and cytoprotective activity. Upon oral administration of SPI-1005, this agent mimics the activity of glutathione peroxidase (GPx) and can utilize glutathione to reduce other unstable molecules, thus preventing the formation of reactive oxygen species (ROS) and reducing oxidative stress on the cell. In the cochlea, this agent may prevent drug-induced injury to the auditory hair cells thereby preventing hearing loss. GPx is the main antioxidant enzyme in the cochlea and protects the inner ear from loud sounds and biochemical damage. In addition, ebselen is able to inhibit the activity of many enzymes involved in inflammation.

In Vitro	Ebselen (SPI-1005; 0.4-100 μM; 20-24 hours) shows strong antiviral effects at a concentration of 10 μM treatment in COVID-19 virus infected Vero cells. Ebsele covalently binds to C145 of the catalytic dyad in COVID-19 virus Mpro. Ebselen inhibits early viral postentry events of the HIV-1 life cycle by impairing the incoming capsid uncoating process. Ebselen permeates the blood-brain barrier and inhibits endogenous inositol monophosphatase in mouse brain. Ebselen inhibits inositol monophosphatase (IMPase). Ebselen inhibits QSOX1 enzymatic activity and suppresses invasion of pancreatic, renal cancer cell lines.
In Vivo	Ebselen (5, 10 mg/kg; IP) decreases 5-HT2 agonist-induced head twitches in a dose-dependent manner.
