Arylcyclohexylamine
class of chemical compounds
Arylcyclohexylamines, also known as arylcyclohexamines or arylcyclohexanamines, are a chemical class of pharmaceutical, designer, and experimental drugs.
History
Phencyclidine (PCP) is believed to be the first arylcyclohexylamine with recognized anesthetic properties, but several arylcyclohexylamines were described before PCP in the scientific literature, beginning with PCA (1-phenylcyclohexan-1-amine) the synthesis of which was first published in 1907. PCP itself was discovered in 1926 but not researched by the pharmaceutical industry until the 1950s. PCE was reported in 1953 and PCMo (4-(1-phenyl-cyclohexyl)-morpholine see chart below for figure) in 1954, with PCMo described as a potent sedative. Arylcyclohexylamine anesthetics were intensively investigated at Parke-Davis, beginning with the 1956 studies of PCP and later the related compound ketamine. The 1970s saw the debut of these compounds, especially PCP and its analogues, as illicitly used recreational drugs due to their dissociative hallucinogenic and euphoriant effects. Since that time, the class has been expanded by scientific research into stimulant, analgesic, and neuroprotective agents, and also by clandestine chemists in search of novel recreational drugs.
Structure
An arylcyclohexylamine is composed of a cyclohexylamine unit with an aryl moiety attachment. The aryl group is positioned geminal to the amine. In the simplest cases, the aryl moiety is typically a phenyl ring, sometimes with additional substitution.
Begin with the source’s own compact description: “Arylcyclohexylamine” is class of chemical compounds. The dossier treats that line as a proposition to test through Arylcyclohexylamine, class and chemical, not as a finished interpretation.
Why this record matters
The phrase “class of chemical compounds” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 1, 2026. The linked authority identifier is Q2866102. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1907, 1926, 1953 and 1954.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
