生物活性 | Lutein (Xanthophyll) is a carotenoid with reported anti-inflammatory properties. A large body of evidence shows that lutein has several beneficial effects, especially on eye health[1]. Lutein exerts its biological activities, including anti-inflammation, anti-oxidase and anti-apoptosis, through effects onreactive oxygen species(ROS)[2][3]. Lutein is able to arrive in the brain and shows antidepressant-like and neuroprotective effects. Lutein is orally active[4]. |
体外研究 (In Vitro) | Lutein (100 or 200 μM) protects against A2-PE (a bis-retinoid compound that is the immediate precursor of the lipofuscin fluorophore A2E) photooxidation and reduces A2E photooxidation[2].

体内研究 (In Vivo) | Lutein (40-160 mg/kg; in diet for 5 weeks) protects against severe traumatic brain injury through anti-inflammation and anti-oxidative effects via ICAM-1/Nrf-2 in rats[3]. Lutein (0.1-10 mg/kg; p.o.; once or daily for 7 and 21 days) preventsCorticosterone(HY-B1618)-induced depressive-like behavior in mice with the involvement of antioxidant and neuroprotective activities[4].
Animal Model: | Sprague-Dawley rats, severe traumatic brain injury (STBI) model[3] | Dosage: | 40, 80 and 160 mg/kg | Administration: | In diet for 5 weeks | Result: | Suppressed, interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein-1 expression, reduced serum ROS levels, and reduced superoxide dismutase and glutathione peroxidase activities. Effectively downregulated the expression of NF-κB p65 and cyclooxygenase-2, intercellular adhesion molecule (ICAM)-1 protein, and upregulated nuclear factor erythroid 2 like 2 (Nrf-2) and endothelin-1 protein levels. |
Animal Model: | Male Swiss mice, chronicCorticosterone(HY-B1618) model of depression[4] | Dosage: | 0.1, 1 and 10 mg/kg | Administration: | Oral administration, once or daily for 7 and 21 days | Result: | Decreased immobility time at the dose 10 mg/kg. Counteracted the behavioral changes displayed byCorticosterone(HY-B1618) showing antidepressant-like effect. Presented antioxidant effect in the hippocampus, prefrontal cortex and plasma of mice, and exhibited a capability to protect hippocampal and prefrontal cortex slices against glutamatergic toxicity. |
