Biological Activity for Ebselen

Ebselen is a glutathione peroxidase mimic; peroxynitrite scavenger. Inhibits ferroptosis. Also inhibits lipoxygenase, cyclooxygenase, nitric oxide synthase, protein kinase C and H⁺/K⁺-ATPase activity. Inhibits the hepatic carcinogenic effects of aflatoxin B₁. Antioxidant and anti-inflammatory. Selectively inhibits G_q protein signaling and enhances differentiation of brown adipocytes. Inhibits SARS-CoV-2 M^pro in vitro (IC₅₀ = 0.67 μM in FRET assay)
