Melatonin (N-acetyl-5-methoxy tryptamine) is a substance which is secreted by multiple organs such as the pineal gland, retina, bone marrow, the gastro-intestinal tract, whose main role is to regulate the circadian rhythm (day and night cycles).
The pineal gland secretes the hormone melatonin (N-acetyl-5-methoxy tryptamine), which suppresses angiotensin II-induced human antigen R expression through the inhibition of NF-KB signaling.

In this study, a new diamine N-[2-(1H-indol-3-yl)ethyl]-3,5-diaminobenzamide (IEDAB) was synthesized using tryptamine as starting material and characterized by FT-IR, [sup.1]H-NMR, [sup.13]C-NMR, and mass spectroscopy.
As already mentioned, a number of studies have highlighted the capacity of AhR to respond to indolyl metabolites, including indoxyl-3-sulfate, 6-formylindolo[3,2b]carbazole, kyneurenine, kynurenic acid, tryptamine, indole-3-acetate, and dietary indoles (indole-3-carbinol and 3,3'-diindolylmethane from the Cruciferous vegetables), thus positioning the AhR as a candidate indole receptor [11, 15, 43, 44].
