Selective 5-HT 2A receptor agonists like the 25-NB compounds, specifically those which can behave as full agonists at this receptor, can cause serotonin syndrome-like adverse effects such as hyperthermia, hyperpyrexia, tachycardia, hypertension, clonus, seizures, agitation, aggression, and hallucinations which has ended in death on numerous ...
This is a list of agonists of the serotonin receptor subtype 5-HT 2A (and other 5-HT 2 subtypes to a varying extent) which fall outside the common structural classes. Most agonists at this receptor are either substituted phenethylamine derivatives from the 2C, DOx and 25-NB groups, or substituted tryptamines and related compounds along with more complex derivatives of these such as ...
The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
5-Methoxytryptamine – full agonist to several serotonin receptors. O-4310 – 5-HT 2A selective, claimed to have 100× selectivity over 5-HT 2C and be inactive at 5-HT 2B PHA-57378 – dual 5-HT 2A / 5-HT 2C agonist, anxiolytic effects in animal studies.
A number of somewhat selective SRAs have been well-studied, for instance fenfluramine and meta-chlorophenylpiperazine (mCPP). [8] [9] Although fenfluramine and mCPP are efficacious SRAs, they are also highly potent agonists of serotonin 5-HT 2 receptors, including of the serotonin 5-HT 2A, 5-HT 2B, and particularly 5-HT 2C receptors.

Serotonin is an endogenous non-selective agonist for the 5-HT 2C receptor with a binding constant of K i = 16.0 nM. When serotonin binds to the receptors, the most important contacts are in TM helixes 3, 5 and 6 (Figure 3), while the other four TM helixes do not interact directly with the serotonin compound.
Serotonin levels within the synapse drop, then rise again, ultimately leading to downregulation of post-synaptic serotonin receptors. [183] Other, indirect effects may include increased norepinephrine output, increased neuronal cyclic AMP levels, and increased levels of regulatory factors such as BDNF and CREB . [ 184 ]
