Dioxadrol exists in four isomeric forms. alpha-(+)-Dioxadrol (dexoxadrol) showed phencyclidine (PCP)-like activity in rhesus monkeys trained to discriminate s.c. administration of ketamine, but neither alpha-(-)-dioxadrol (levoxadrol) nor beta-(+/-)-dioxadrol showed such activity. In addition, response-contingent i.v. dexoxadrol maintained higher rates of responding than either levoxadrol or...
Metaphit, a derivative of phencyclidine (PCP), binds irreversibly to PCP sites and appears to act as an antagonist of PCP under some conditions and as a PCP-like agonist under other conditions. To describe further these conditions, the authors investigated the behavioral effects of metaphit by using different routes of administration, behavioral procedures and species. In pigeons, metaphit...
