In Vitro

N-Acetyl-5-hydroxytryptamine (NAS), a precursor of Melatonin, is acetylated from serotonin by AANAT (arylalkylamine N-acetyltransferase). 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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

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 suggest that NAS strongly provokes both wild-type TrkB and TrkB F616A tyrosine phosphorylation and activation^[1].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Animal Administration^[1]

Mice^[1]
Two-month-old TrkB F616A mice are pretreated with 1NMPP1 in drinking water (50 μM) 1 day before the experiment, followed by administration of N-Acetyl-5-hydroxytryptamine (20 mg/kg, i.p.) or Melatonin (1 mg/kg, i.p.). Mice are killed at 1 h. The brain homogenates are analyzed by immunoblotting with anti-p-TrkB. Two- to three-month-old BDNF forebrain conditional knockout mice are injected i.p. with N-Acetyl-5-hydroxytryptamine or Melatonin. Mice are killed at 0, 0.5, 1, or 2 h following drug administration. Brain lysates are prepared and analyzed by immunoblotting with anti-phospho-TrkB Y816^[1].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
