Dextromethorphan (3-methoxy-17-methylmorphinan) has complex pharmacologic effects on the central nervous system. Although some of these effects are neuropsychotoxic, this review focuses on the neuroprotective effects of dextromethorphan and its analogs. Some of these analogs, particularly dimemorfan (3-methyl-17-methylmorphinan) and 3-hydroxymorphinan, have promising neuroprotective properties with negligible neuropsychotoxic effects. Their neuroprotective effects, the mechanisms underlying these effects, and their therapeutic potential for the treatment of diverse neurodegenerative disorders are discussed.

Parishin C, a major component of Gastrodia elata BLUME (GE), was purified from GE. Because GE modulates the serotonergic system and the 5-HT1A receptor is an important therapeutic target of schizophrenia, we examined whether parishin C affects phencyclidine-induced abnormal behaviors in mice. Phencyclidine-induced abnormal behaviors were significantly ameliorated by parishin C. These effects were reversed by WAY 100635, a 5HT1A–receptor antagonist. Consistently, parishin C showed high affinity at 5-HT1A receptor as well as a 5-HT1A–agonist activity in a 8-OH-DPAT–stimulated [35S]GTP-γS binding assay. Our results suggest that the antipsychotic effects of parishin C require activation of 5-HT1A receptors.

Drug abuse involving dextromethorphan, an antitussive, has been a social problem in various geographic locations since the 1960s. Ironically, high doses of the drug confer neuroprotective activity with central nervous system and behavioral effects. Accumulating evidence suggests that metabolism to phencyclidine-like dextrorphan is not essential for the neuroprotective activity of dextromethorphan. Here, we review the neuroprotective properties of dextromethorphan and its potential for abuse and the potential neuroprotective effects of the drug’s analogs and 3-hydroxymorphinan, a metabolite of dextromethorphan. These compounds may provide a novel therapeutic direction for the treatment of neurodegenerative diseases such as convulsive or parkinsonian-like disorders.
