To provide an excellent agent for preventing or treating dementia and schizophrenia based on serotonin 5-HT
5A
receptor regulating action, it was found that a tetrahydroisoquinoline derivative characterized by a structure in which an acylguanidino group binds to a N atom of a tetrahydroisoquinoline ring or the like, and a cyclic group binds to an unsaturated ring has a potent 5-HT
5A
receptor regulating action and an excellent pharmacological action based on the regulating action and also discovered that the tetrahydroisoquinoline derivative is useful as an agent for treating or preventing dementia, schizophrenia, and the like, whereby the present invention has been completed.

The development of a series of GABA(A) alpha 2/alpha 3 subtype selective pyridazine based benzodiazepine site agonists as anxiolytic agents with reduced sedative/ataxic potential is described, including the discovery of 16, a remarkably alpha 3-selective compound ideal for in vivo study. These ligands are antagonists at the alpha 1 subtype, with good CNS penetration and receptor occupancy, and excellent oral bioavailability.
