5-Carboxamidotryptamine (5-CT), also known as5-(aminocarbonyl)tryptamine, is atryptaminederivative closely related to theneurotransmitterserotonin.[1]

5-CT acts as anon-selective,high-affinityfull agonist at the5-HT1A,5-HT1B,5-HT1D,5-HT5A, and5-HT7 receptors, as well as an agonist of the5-HT2,5-HT3,5-HT6 receptors with lower affinity.[2][3][4][5] It has negligible affinity for the5-HT1E and5-HT1F receptors.[6][1] 5-CT binds most strongly to the 5-HT1A receptor and it was once thought to be selective for this site.[7][8][1]

In 2018, a close derivative of 5-CT,AH-494 has been shown to function as an agonist of5-HT7, although being more selective over5-HT1A.[9] Structural study indicated residue Ser5x43 might play critical roles in the selectivity of 5-CT across the serotonin receptor family.[10]
