General description

Ebselen is a sympathomimetic amine.

Application

Ebselen has been used as a:
  • voltage-dependent calcium channels (VDCCs) blocker
  • glutathione peroxidase mimetic to test its inhibitory effect on contraction-mediated deoxy glucose (2-DG) uptake in mouse

extensor digitorum longus (fast-twitch) muscle
  • glucocerebrosidase inhibitor
  • hepatitis C virus helicase inhibitor

Biochem/physiol Actions

An organo-selenium compound possessing antioxidant properties. Inhibits mammalian lipoxygenases in the absence of thiol groups, and glutathione S-transferase and papain via the interaction with cysteine residues. Also inhibits indoleamine 2,3-dioxygenase by covalently modifying a cysteine residue, the effect being reversible with dithiothreitol. Inhibits oxidation of low density lipoproteins (LDL).
Ebselen, a glutathione-peroxidase-mimic, elicits anti-inflammatory activity. It also has anti-atherosclerotic functionality. Ebselen displays antibacterial action on) multidrug-resistant Staphylococcus aureus (MRSA) infections and could be a potential therapeutic target for treating MRSA based skin infection. It is regarded as neuroprotective agent and elicits chemopreventive functionality in inflammation-associated carcinogenesis.
