一般說明

虾青素(AST)是一种红色的膳食类胡萝卜素。它主要存在于水生动物和微藻中,如雨生红球藻(Haematococcus pluvialis)和小球藻(Chlorella zofingiensis)。

應用

虾青素已被用于:
  • 作为抗氧化剂来研究其对臂尾轮虫(Brachionus manjavacas)(轮虫纲)种群生长的影响
  • 研究其对糖尿病性视网膜病变治疗的影响。
  • 通过人前列腺 LNCaP 细胞的表观遗传修饰,研究其在恢复 Nrf2(核因子红细胞 2 p45 相关因子 2)和谷胱甘肽 S-转移酶 P1(GSTP1)表达中的作用。

生化/生理作用

体内体外研究提出虾青素(AST)具有促进健康的活性,表明其可用于预防多种疾病,例如癌症和帕金森病。由于其颜色鲜红,AST 已用作动物饲料中的食用色素。
虾青素是一种有效的抗氧化剂,具有抗增殖、神经保护和抗炎作用。 虾青素可防止氧化应激,抑制 NF-KB,抑制促炎基因,抑制促炎化合物一氧化氮、前列腺素 E2、TNF-α 和白细胞介素-1β 的产生。 虾青素′对 TNF-α 和棕榈酸产生的氧化应激的保护作用已被证明可以改善胰岛素抵抗。 虾青素也被证明是 PPARγ 的抑制剂。

Exercise-induced reactive oxygen and nitrogen species are increasingly considered as beneficial health promotion. Astaxanthin (ASX) has been recognized as a potent antioxidant suitable for human ingestion. We investigated whether ASX administration suppressed antioxidant enzyme activity in moderate-intensity exercise. Seven-week-old male
