褪黑激素(N-乙酰基-5-甲氧基色胺)是由必需氨基酸色氨酸合成而来的。它是一种松果体神经激素。由褪黑激素诱导的直接、非受体介导的自由基清除活性使其与其他经典激素不同。褪黑激素在多种生物中表达,如细菌、藻类、真菌、植物、昆虫和包括人类在内的脊椎动物。褪黑激素已被实验性动物摄入用于以下研究: · 确定长期的褪黑激素摄入是否能够诱导生殖变化以及褪黑激素如何在排卵期间发挥其与大鼠卵巢中脂质氧化和抗氧化活性相关的保护作用。 · 确定褪黑激素对缺氧缺血后新生大鼠神经细胞内质网应激和sirtuin 1表达的影响。 · 在应激小鼠中研究褪黑激素慢性应激诱导的肠功能障碍的影响。
Information
Melatonin (NSC 113928) Melatonin (NSC 113928, NSC 56423, N-Acetyl-5-methoxytryptamine) is a MT receptor agonist, used as a dietary supplement. Melatonin is a selective ATF-6 inhibitor and downregulates COX-2 . Melatonin enhances mitophagy and regulates
In vitro
Melatonin interacts with the highly toxic hydroxyl radical with a rate constant equivalent to that of other highly efficient hydroxyl radical scavengers. Melatonin reportedly neutralizes hydrogen peroxide, singlet oxygen, peroxynitrite anion, nitric oxide and hypochlorous acid. Melatonin is believed to scavenge the highly toxic hydroxyl radical, the peroxynitrite anion, and possibly the peroxyl radical. Melatonin reportedly scavenges the superoxide anion radical and it quenches singlet oxygen. Melatonin stimulates mRNA levels for superoxide dismutase and the activities of glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase (all of which are antioxidative enzymes), thereby increasing its antioxidative capacity. Melatonin in cell-free systems has been shown to directly scavenge H2O2, singlet oxygen (1O2) and nitric oxide (NO*), with little or no ability to scavenge the superoxide anion radical (O2*-) in vitro. Melatonin also directly detoxifies the peroxynitrite anion (ONOO-) and/or peroxynitrous acid (ONOOH), or the activated form of this molecule, ONOOH*. Melatonin acts as a direct free radical scavenger with the ability to detoxify both reactive oxygen and reactive nitrogen species. Melatonin inhibits cAMP accumulation in most of the cells examined, but the indole effects on other messengers have been often observed only in one type of the cells or tissue, until now. Melatonin also regulates the transcription factors, namely, phosphorylation of cAMP-responsive element binding protein and expression of c-Fos.
