Possible differences in modes of agonist and antagonist binding at human 5-HT6 receptors

A graphics model of the human 5-HT6 receptor was constructed and automated docking studies were performed. The model suggests that 5-HT6 antagonist arylsulfonyltryptamines might bind differently than that of the agonist serotonin. Furthermore, the model explains many of the empirical results from our previous structure–affinity studies.
