Findings indicated that astaxanthin had neuroprotective effects against retinal damage in-vitro and in- vivo, and that its protective effects may have been partly mediated via its antioxidant effects.
Anti-oxidative, anti-tumor-promoting, and anti-carcinogenic activities of adonirubin and adonixanthin.
Adonirubin and adonixanthin exhibited an inhibitory effect on Epstein-Barr virus early antigen activation in Raji cells and carcinogensis of mouse skin tumors initiated by 7,12-dimethylbenz[a]anthracene and promoted by 12-O-tetradecanoylphorbol-13-acetate.
Astaxanthin, a dietary carotenoid, protects retinal cells against oxidative stress in‐vitro and in mice in‐vivo
Findings indicated that astaxanthin had neuroprotective effects against retinal damage in‐vitro and in-vivo, and that its protective effects may have been partly mediated via its antioxidant effects.
Protective effects of a dietary carotenoid, astaxanthin, against light-induced retinal damage.
Astaxanthin has protective effects against light-induced retinal damage via the mechanism of its antioxidative effect, and is well known as a powerful antioxidant.
Astaxanthin analogs, adonixanthin and lycopene, activate Nrf2 to prevent light-induced photoreceptor degeneration.
Protective Effects of Astaxanthin from Paracoccus carotinifaciens on Murine Gastric Ulcer Models
The results suggest that astaxanthin has antioxidant properties and exerts a protective effect against ulcer formation in murine models.
Astaxanthin Protects Against Retinal Damage: Evidence from In Vivo and In Vitro Retinal Ischemia and Reperfusion Models
Results indicate that astaxanthin inhibits ischemia-induced retinal cell death via its antioxidant effect, and might be effective in treating retinal ischemic pathologies.
