(S)-DCPT is an experimental drug from the 2-aminotetralin family, related to the selective 5-HT<sub>1A</sub> agonist 8-OH-DPAT. However, (S)-DPCT instead acts as a selective agonist for the 5-HT<sub>1B</sub> receptor, with moderate selectivity over 5-HT<sub>1D</sub> and good selectivity over 5-HT<sub>1A</sub>, 5-HT<sub>7</sub>, and other serotonin receptors.
