产品描述 | N-Acetyl-5-hydroxytryptamine (O-Demethylmelatonin) , also known as Normelatonin, is the immediate precursor of melatonin. It is produced from serotonin by the enzyme aralkylamine N-acetyltransferase and is converted to melatonin by acetylserotonin O-methyltransferase. It can potently activate TrkB receptor. |
体外活性 | N-acetylserotonin activates TrkB receptor in a circadian rhythm. N-Acetyl-5-hydroxytryptamine swiftly activates TrkB in a circadian manner and exhibits antidepressant effect in a TrkB-dependent manner. N-Acetyl-5-hydroxytryptamine rapidly activates TrkB, but not TrkA or TrkC, in a neurotrophin- and MT3 receptor-independent manner[1]. |
体内活性 | To explore whether N-Acetyl-5-hydroxytryptamine, can trigger TrkB activation in vivo, TrkB F616A knockin mice are employed, where it has been shown that TrkB F616A activation can be selectively blocked by 1NMPP1, a derivative of kinase inhibitor PP1, leading to TrkB-null phenotypes. To assess whether N-Acetyl-5-hydroxytryptamine can mimic BDNF, cortical neurons from TrkB F616A knockin mice are prepared. In alignment with a previous report, BDNF- and NAS-mediated TrkB phosphorylation are selectively reduced by 1NMPP1 but not by K252a, whereas serotonin or Melatonin had no effect. These findings indicate that NAS strongly provokes both wild-type TrkB and TrkB F616A tyrosine phosphorylation and activation[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
