Substituted 3-benzazepine
class of chemical compounds

A substituted 3-benzazepine, or simply 3-benzazepine, is a derivative of 3-benzazepine. They are cyclized phenethylamines and are closely related to the tetrahydroisoquinolines. In addition, they are analogous to the cyclized tryptamine ibogalogs and their β-carboline relatives.
3-Benzazepines are known to act as monoamine receptor modulators, including as dopamine D1-like receptor agonists, dopamine D1 receptor antagonists, and serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptor agonists, among other activities. 3-Benzazepines acting as serotonin 5-HT2 receptor agonists generally show varying degrees of preferential activity at the serotonin 5-HT2C receptor over the serotonin 5-HT2A receptor, with occasional exceptions. One 3-benzazepine, the non-selective serotonin 5-HT2 receptor agonist and previously marketed anorectic lorcaserin (Belviq), is known to produce psychedelic effects at supratherapeutic doses.

Why this record matters
“Substituted 3-benzazepine” is worth following because a concise public description often conceals a longer documentary argument. Here, Substituted, 3-benzazepine and class provides the most credible route into that argument.
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 Apr 4, 2026. The linked authority identifier is Q136659439.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
