Interactions

3-Me-2'-oxo-PCE (also known as Deoxymethoxetamine, DMXE, 3D-MXE) is a dissociative substance of the arylcyclohexylamine class that produces ketamine-like dissociative effects when administered. It is structurally related to MXE, ketamine, PCE, and 3-MeO-PCP.

DMXE has been sold online since around October 2020, marketed as a legal replacement for MXE after the global ban of the substance made it extinct.

Limited data exists about the pharmacological properties, metabolism, and toxicity of DMXE in humans, and it has a limited history of human use. It is highly advised to use harm reduction practices if using this substance.

History and culture

The compound does not have a clear first synthesis date. DMXE was first reported as being used for recreational purposes in 2020, and has been increasing in popularity as an alternative to the now-banned MXE. DMXE, alongside another compound, MXiPr, have been sold online as a research chemical since around October 2020.

It is rarely sold on the streets and is almost exclusively sold as a gray-area research chemical alternative to the more recognizable MXE for recreational and entheogenic purposes.

Chemistry

DMXE (Deoxymethoxetamine), or 2-(ethylamino)-2-(3-methylphenyl)-cyclohexanone, is classed as an arylcyclohexylamine, similar to PCP, ketamine, and MXE, which include a cyclohexane ring bound to an aromatic ring along with an amine group. It is an analog of MXE (Methoxetamine) distinguished by the replacement of the methoxy group at the 3-position with a methyl group. This modification removes an oxygen atom, hence Deoxy-(without oxygen)-methoxetamine, creating a more hydrophobic and less bulky molecule, which slightly alters its pharmacological effects compared to MXE.

DMXE features a phenyl ring that has a methyl (CH₃) substituent at the R₃ position, which is connected to a cyclohexane structure. This cyclohexane ring is modified at the R₂ position with an oxo group, defining it as a cyclohexanone. Attached to the same site (R₁) on the cyclohexanone ring is an ethylamino chain (-N-CH₂CH₃).

It is a white crystalline solid at room temperature that is sparingly soluble at 10mg/mL in ethanol as well as DMSO. DMXE is stable for approximately 5 years when stored at -20°C.

Pharmacology

DMXE acts as a non-competitive NMDA receptor antagonist. NMDARs (N-methyl-D-aspartate receptors) are specific types of glutamate receptors which modulate the transmission of electrical signals between neurons in the brain and spinal cord; for the signals to pass, the receptor must be open. The substance has shown a IC₅₀ (half-maximal inhibitory concentration), which measures the potency of DMXE and related compounds in blocking NMDARs, of 0.679mM, indicating significant potency. DMXE and related compounds bind to the phcyclidine (PCP) site of NMDARs, which was determined via in silico docking results. This binding is implicated in the antagonistic activity observed, which includes the blocking of NMDA-induced inward currents in a dose-dependent manner. DMXE shows a high affinity and potent inhibitory capacity comparable to that of other MXE analogs like MXiPr and O-desmethyl MXE, with some variations in potency explained by different interactions at the receptor site. Additionally, DMXE significantly reduces excitatory postsynaptic currents (EPSCs) evoked in the presence of NMDA.

Dissociatives inhibit the normal functioning NMDA receptors by binding to and blocking them. This disruption of neural network activity leads to loss of normal cognitive and affective processing, psychomotor functioning, anesthesia and eventually the equivalent of a “k-hole.”

Subjective effects

This subjective effects section is a stub. As such, it is still in progress and may contain incomplete or wrong information. You can help by expanding or correcting it.

Disclaimer: The effects listed below cite the Subjective Effect Index (SEI), an open research literature based on anecdotal user reports and the personal analyses of PsychonautWiki contributors. As a result, they should be viewed with a healthy degree of skepticism.

It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠.

Physical effects

• • Stimulation and Sedation - DMXE has been compared to MXE which is known for its especially sedating and relaxing effects. However dissociatives are also able to induce stimulation, usually in lower doses.
  • Pain relief
  • Motor control loss
  • Tactile suppression
  • Physical euphoria

Disconnective effects

• • Tactile disconnection
  • Visual disconnection - This eventually results in DMXE's equivalent of the "k-hole" or more specifically, holes, spaces and voids alongside of structures.

Visual effects

• Suppression

  • Visual acuity suppression
  • Double vision

  Distortions

  • Perspective distortions

  
  

  Geometry

  If applicable, a brief paragraph summary describing the visual geometry produced by the substance may be included here.

  Hallucinatory states

  If applicable, a brief summary of the substance's visual effects profile may be written here.

  • Internal hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots)
  • External hallucination (autonomous entities; settings, sceneries, and landscapes; perspective hallucinations and scenarios and plots)

Cognitive effects

• The general head space of DMXE, like MXE, is often described as particularly euphoric and clear-headed in comparison to that of DXM and ketamine.
  • Amnesia
  • Anxiety suppression
  • Depersonalization
  • Derealization
  • Dream potentiation
  • Ego death
  • Immersion enhancement
  • Increased music appreciation
  • analysis suppression
  • Introspection
  • Mania
  • Memory suppression
  • Personal meaning enhancement
  • Thought deceleration
  • Time distortion

Auditory effects

• • Distortions
  • Hallucinations
  • Suppression

Toxicity and harm potential

Further information: Research chemicals § Toxicity and harm potential, and Responsible use

Due to its similarity to MXE, it is advised to use MXE's safety profile when taking this substance. The toxicity and long-term health effects of recreational DMXE use specifically have not been researched.

This is because DMXE is a research chemical with a very brief history of human usage.

It is strongly recommended that one use harm reduction practices when using this substance.

Dangerous interactions

Warning: Many psychoactive substances that are reasonably safe to use on their own can suddenly become dangerous and even life-threatening when combined with certain other substances. The following list provides some known dangerous interactions (although it is not guaranteed to include all of them).

Always conduct independent research (e.g. Google, DuckDuckGo, PubMed) to ensure that a combination of two or more substances is safe to consume. Some of the listed interactions have been sourced from TripSit.

• DOx - As an NMDA antagonist MXE potentiates DOx which can be unpleasantly intense.
• 25x-NBOMe - As an NMDA antagonist MXE potentiates NBOMes which can be unpleasantly intense.
• 2C-T-x
• PCP - There are no reports available about this combination.
• Amphetamines - Risk of tachycardia, hypertension, and manic states.
• MDMA - There have been reports of risky serotonergic interactions when the two are taken at the same time, but MXE taken to the end of an MDMA experience does not appear to cause the same issues.
• Cocaine - Stimulants taken with MXE can lead to hypermanic states much more easily, especially if sleep is avoided.
• Benzodiazepines - Both substances potentiate the ataxia and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. Place affected patients in the recovery position to prevent vomit aspiration from excess.
• SSRIs - Depending on the SSRI this combination can be unpredictable.
• MAOIs - MAO-B inhibitors appear to increase the potency of MXE. MAO-A inhbitors have some negative reports associated with the combination but there isn't much information available.
• ΑMT
• Alcohol - There is a high risk of memory loss, vomiting and severe ataxia from this combination.
• GHB - Both substances cause ataxia and bring a risk of vomiting and unconsciousness. If the patient falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.
• GBL - Both substances cause ataxia and bring a risk of vomiting and unconsciousness. If the patient falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.
• Opioids - This combination can potentiate the effects of the opioid.
• Tramadol

Legal status

• US: DMXE itself is not scheduled, but due to its similarities to now schedule I MXE, one can be prosecuted for under the Federal Analog Act, which states any chemical "substantially similar" to a controlled substance listed in Schedule I or II to be treated as if it were listed in Schedule I, but only if intended for human consumption.
• CA: DMXE is on Schedule 1 in Canada.
• DE: DMXE is regulated under the NpSG in Germany.
• UK: DMXE is scheduled under Class B in the United Kingdom.
