生物活性

製品説明 Astaxanthin (β-Carotene-4,4'-dione, Trans-Astaxanthin), a xanthophyll carotenoid, is a nutrient with unique cell membrane actions and diverse clinical benefits with excellent safety and tolerability.
in vitro Astaxanthin is a carotenoid nutrient with molecular properties that precisely position it within cell membranes and circulating lipoproteins, thereby imbuing them with potent antioxidant and anti-inflammatory actions. Astaxanthin also effectively protects the double membrane system of mitochondria, to the point of boosting their energy production efficiency. In cultured cells, astaxanthin protects the mitochondria against endogenous oxygen radicals, conserves their redox (antioxidant) capacity, and enhances their energy production efficiency. Astaxanthin has also protected human LDL against oxidative attack. Astaxanthin specifically protects the mitochondria of cultured nerve cells against toxic attack and stimulates the proliferation of cultured nerve stem cells. It effectively protects cultured nerve cells against hydrogen peroxide toxicity, and down-regulates genes linked to cell death and up-regulates genes linked to cell survival[1].
in vivo In pharmacokinetic studies, after ingestion of esterified natural astaxanthin, only unesterified astaxanthin appears in the blood. Astaxanthin's bioavailability is substantially affected by meal timing and by smoking. Supplementation with astaxanthin may lower lipid peroxidation in vivo. Astaxanthin significantly improves the memory performance of mice in the Morris water maze. It has demonstrated safety in numerous human clinical trials. The doses of astaxanthin used in clinical trials have ranged from 1 mg/day to 40 mg/day (with the majority in the 6-12 mg range); single-dose pharmacokinetic studies use up to 100 mg per dose[1].

細胞アッセイ 細胞株 Vero cells
濃度 1, 5, 10, 20, or 30 μg/100 μL
反応時間 24 h
実験の流れ Vero cells (5 × 103/well) are seeded and cultured for 24 h and then infected with trypomastigotes (10 parasites/cell). Once intracellular parasites are observed (about 96 h after infection), the old medium is replaced with fresh supplemented DMEM with different ASTX (Astaxanthin) doses (1, 5, 10, 20, or 30 μg/100 μL). As a control, co-cultures are kept with NFMX (400 μg/100 μL) or with no ASTX or NFMX supplementation. After 24 h of incubation, microscopic morphological changes in the co-culture, such as loss of normal shape of T. cruzi infected Vero cell, changes of normal parasite shape or motility, and variations in the presence of intra- or extra-cellular parasites are evaluated by a trained technician. Additionally, parasite viability is evaluated by Trypan blue stain assay.
動物実験 動物モデル BALB/c mice (4-6 weeks old) infected with Trypanosoma cruzi
投薬量 10 mg/kg/day
投与方法 oral administration
