5-Carboxamidotryptamine (5-CT) is a tryptamine derivative closely related to the neurotransmitter serotonin.

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 at the 5-HT2, 5-HT3, 5-HT6 receptors with lower affinity.[1][2][3] It has negligible affinity for the 5-HT1E and 5-HT1F receptors.[4] 5-CT binds strongest to the 5-HT1A receptor and it was once thought to be selective for this site.[5][6] 5-CT also acts as a serotonin releasing agent.
