Ro 04-6790 is a drug, developed by Hoffmann–La Roche, which has applications in scientific research. It acts as a potent and selective receptor antagonist for the 5-HT6 serotonin receptor subtype, with little or no affinity at other receptors. In common with other drugs of this class,[1] Ro 04-6790 has nootropic effects in animals,[2] and reduces the amnesia produced by memory-impairing drugs such as dizocilpine[3] and scopolamine.[4]
