產(chǎn)品描述 Melatonin是一種 MT receptor 激動(dòng)劑激素, 用作膳食補(bǔ)充品。Melatonin 是一種選擇性的 ATF-6 的抑制劑并可下調(diào) COX-2。Melatonin 可增強(qiáng)線粒體自噬并調(diào)節(jié)凋亡和自噬的穩(wěn)態(tài)。

Melatonin與高毒性羥基自由基相互作用，數(shù)率常數(shù)等于其他高效羥基自由基清除劑。Melatonin被報(bào)到能夠中和過氧化氫，單線態(tài)氧，過氧亞硝基陰離子，一氧化氮和次氯酸。[1]

Melatonin被認(rèn)為能夠清除高毒性羥基自由基，過氧亞硝酸鹽陰離子，可能也作用于氫過氧自由基。據(jù)報(bào)道，Melatonin清除超氧陰離子自由基，并且能夠淬滅單線態(tài)氧。Melatonin刺激超氧化物歧化酶的mRNA水平，并活化谷胱甘肽過氧化物酶，谷胱甘肽還原酶和葡萄糖-6-磷酸脫氫酶(都為抗氧化酶)，從而增加其抗氧化能力。[2]

在體外，Melatonin在無細(xì)胞體系中被證實(shí)能夠直接清除H2O2，單線態(tài)氧(1O2)和一氧化氮(NO*)，幾乎或完全沒有清除超氧陰離子自由基(O2*-)的能力。Melatonin也能夠直接作用于過氧亞硝基陰離子(ONOO-)和/或過氧亞硝酸(ONOOH)，或該分子的活化形式，ONOOH*，使它們失去毒性。Melatonin作為一種直接自由基清除劑，具有清除活性氧和活性氮自由基毒性的能力。[3]

Melatonin抑制大部分檢測細(xì)胞中的cAMP積累，但至今為止，對其它信使吲哚基的作用僅在一種類型的細(xì)胞或組織中經(jīng)常觀察到。Melatonin也能夠調(diào)節(jié)轉(zhuǎn)錄因子，即cAMP響應(yīng)元件結(jié)合蛋白的磷酸化和c-Fos的表達(dá)。[4]
