5-Carboxamidotryptamine
Template:Short description Template:Cs1 config Template:Drugbox
5-Carboxamidotryptamine (5-CT), also known as 5-(aminocarbonyl)tryptamine, is a tryptamine derivative closely related to the neurotransmitter serotonin.[1]
5-CT acts as a non-selective, high-affinity full agonist at the 5-HT1A, 5-HT1B, 5-HT1D, 5-HT5A, and 5-HT7 receptors, as well as an agonist of the 5-HT2, 5-HT3, 5-HT6 receptors with lower affinity.[2][3][4][5] It has negligible affinity for the 5-HT1E and 5-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 of 5-HT7, although being more selective over 5-HT1A.[9] Structural study indicated residue Ser5x43 might play critical roles in the selectivity of 5-CT across the serotonin receptor family.[10]
