3-Hydroxymorphinan (3-HM), or morphinan-3-ol, is a psychoactive drug of the morphinan family.[1] It is the racemic counterpart to norlevorphanol.

The dextrorotatory stereoisomer of the compound is an active metabolite of dextromethorphan, dextrorphan, and 3-methoxymorphinan,[2] and similarly to them has potent neuroprotective and neurotrophic effects on LTS- and MPTP-treated dopaminergic neurons of the nigrostriatal pathway,[3][4] but notably without producing any neuropsychotoxic side effects (e.g., dissociation or hallucinations) or having any anticonvulsant actions.[5][6] It does not seem to bind to the NMDA receptor,[6] and instead, its neuroprotective properties appear result from inhibition of glutamate release via the suppression of presynaptic voltage-dependent Ca2+ entry and protein kinase C activity.[7] In any case, as such, the compound has been investigated as a potential management of Parkinson's disease medication (antiparkinsonian agent). A prodrug, GCC1290K, has been developed on account of 3-HM's poor bioavailability (18%), and a New Drug Application has been approved for it by the United States Food and Drug Administration.[6] It is currently undergoing clinical trials for the treatment of Parkinson's disease.[6] It does not have a Controlled Substances Act 1970 schedule, ACSCN, or annual aggregate manufacturing quota and may not necessarily be controlled, whilst norlevorphanol is; none of the dextrorotary derivatives of the dromoran and norlevorphanol sub-families of morphinan derivatives are controlled as they do not have opioid activity but the other racemic compounds are.[8]

3-HM's levorotatory stereoisomer, norlevorphanol, in contrast to (+)-3-HM, is an opioid analgesic.[9] It was never marketed as such however, probably due to a combination of the facts that norlevorphanol has low bioavailability and that its potency is diminished compared to its N-methylated analogue levorphanol.[10]

(+)-3-Hydroxymorphinan the Dextro isomer of 3-hydroxymorphinan. The Dextro form is metabolite of 3-methoxymorphinan which is metabolite of Dextromethorphan
