ebselen

Ebselen (CCG-39161) is a organoselenium compound with anti-inflammatory, anti-oxidant and cytoprotective activity. Ebselen acts as a glutathione peroxidase mimetic and is thereby able to prevent cellular damage induced by reactive oxygen species (ROS). In addition, this agent inhibits the activity of a variety of enzymes including nitric oxide synthase (NOS), 5-lipoxygenase, cyclooxygenase, protein kinase C (PKC), NADPH oxidase and gastric H+ K+-ATPase. Furthermore, ebselen may be neuroprotective due to its ability to neutralize free radicals upon NMDA receptor activation thus, reducing lipoperoxidation mediated by glutamate-induced excitotoxicity.

Ebselen oxide (EB-2), a novel variant of HER2 inhibitor for HER2-positive cancers, is an EB-1 analog with antibacterial and antifungal activity, and has shown cytoprotective effects in vitro in addition to cytoprotective effects against HN2.Ebselen oxide inhibits alginate production by Pseudomonas aeruginosa and inhibits HDAC1, HDAC3, HDAC3, and HDAC3. Ebselen oxide inhibits alginate production by Pseudomonas aeruginosa, inhibits HDAC1, HDAC3, HDAC4, HDAC5, HDAC6, HDAC7, HDAC8, and HDAC9, and can be used in the study of fungal infections.

Ebselen derivative 1 (Compound 19), an orally active glutathione peroxidase (GPx) mimic, exhibits notable protective effects against cisplatin-induced hair cell (HC) damage in both in vitro and in vivo settings. It significantly reduces oxidative stress, apoptosis, and ferroptosis in hair cells, making it useful in the study of cisplatin-induced hearing loss [1].

MitoEbselen-2 is a radiation mitigator which reduces lipid hydroperoxides and prevents apoptotic cell death. When administered 24 hours postirradiation, MitoEbselen-2 was shown to increase the survival of mice exposed to whole body γ-irradiation.

Carboxyebselen (HOOC-Ebs) is an endothelial nitric oxide synthase (eNOS) inhibitor that is potent and selective.
