Ebselen is a selenoorganic compound with glutathione peroxidase-like activity and is an anti-inflammatory and antioxidant agent[1]. Ebselen is an inhibitor of inositol monophosphatase (IMPase) with an IC50 of 1.5μM[2]. Ebselen is a potent scavenger of hydrogen peroxide and hydroperoxides, including membrane-bound phospholipid and cholesterol ester hydroperoxides[3]. Ebselen can penetrate the blood-brain barrier and has anti-inflammatory, antioxidant and anti-cancer activities[4].
In vitro, Ebselen (0-100μM) treatment of U266 and RPMI8226 cells for 24h reduced cell viability in a concentration-dependent manner, induced cell apoptosis, increased the generation of intracellular ROS, and induced the translocation of Bax protein from the cytosol to the mitochondria[5]. Ebselen (5-10μM) treatment of V79 cells reduced hydrogen peroxide-induced DNA damage[6]. Ebselen (10-20μM) inhibited the growth of A549 lung cancer cells, Calu-6 lung cancer cells and primary normal human lung fibroblasts (HPF) cells, with IC50 values of approximately 12.5μM, 10μM and 20μM, respectively[7].
In vivo, Ebselen (10mg/kg) was intraperitoneally injected into rats with spinal cord injury (SCI), which reduced the levels of malondialdehyde (MDA) and protein carbonyl (PC) in spinal cord tissue and prevented the inhibition of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) enzyme activities in tissues induced by SCI[8].

| Cell experiment [1]: | |
Cell lines | U266、RPMI8226 cells |
Preparation Method | Cells were treated with 0 (control), 10, 20, 30, 40, 50, and 100μM Ebselen for 24h, respectively. Concentration dependent changes of cell viability determined by CCK-8 assay in cells. |
Reaction Conditions | 0, 10, 20, 30, 40, 50, 100μM; 24h |
Applications | Ebselen induced a decrease in cell viability in a concentration-dependent manner. |
| Animal experiment [2]: | |
Animal models | Wistar albino rats |
Preparation Method | Rats were allotted in six experimental groups: A (control), B (only laminic tomy), C (Trauma; laminectomy+spinal trauma), D (Placebo group; laminectomy+spinal trauma+serum physiology), E (Methylprednisolone group; laminectomy+spinal trauma+Methylprednisolone treated), F (Ebselen group; laminectomy+spinal trauma+Ebselen treated), each containing six rats. Group A, B and C were not treated by any drug. Group D received 1 mL serum physiology, group E received 30mg/kg Methylprednisolone intraperitoneally (i.p.) and group F received 10mg/kg Ebselen i.p. just after the trauma. Rats were examined neurologically at 24h after trauma and spinal cord tissue samples were harvested for both biochemical and histopathological evaluation. |
Dosage form | 10mg/kg; i.p. |
Applications | Ebselen treatment reduced malondialdehyde (MDA) and protein carbonyl (PC) levels in spinal cord tissue and prevented SCI-induced inhibition of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) enzyme activities in the tissue. |
