Experiments were conducted to examine the molecular basis for the high affinity and potency of a new class of 5-HT2A receptor agonists, N-benzyl phenethylamines. Competition binding assays at several serotonin receptors confirmed that an N-arylmethyl substitution was necessary for affinity increases up to 300-fold over simple N-alkyl homologs, as well as enhanced selectivity for 5-HT2A versus 5-HT2C and 5-HT1A receptors. PI hydrolysis functional assays confirmed that these N-benzyl…

Aromatic interactions impact ligand binding and function at serotonin 5-HT2C G protein-coupled receptors: receptor homology modelling, ligand docking, and molecular dynamics results validated by experimental studies
TLDR
To predict and validate molecular determinants for 5-HT2C-specific activation, results from receptor homology modelling, ligand docking, and molecular dynamics simulation studies were compared with experimental results for ligand binding and function at wild type and W6.52A point-mutated 5- HT2C receptors.
5-HT2 receptor binding, functional activity and selectivity in N-benzyltryptamines
TLDR
Although some N-benzyltryptamines might be abuse-liable, others might represent new leads for the development of therapeutics for weight loss, erectile dysfunction, drug abuse, or schizophrenia.

TLDR
This is the first comparative evaluation of the functional effects of the positioning of the methoxy groups in the phenethylamine moiety of NBOMes, and the optimal substitution pattern of N-unsubstituted phenylalkylamines has been extensively studied.
N-Benzyl-5-methoxytryptamines as Potent Serotonin 5-HT2 Receptor Family Agonists and Comparison with a Series of Phenethylamine Analogues
TLDR
A series of N-benzylated-5-methoxytryptamine analogues was prepared and investigated, with special emphasis on substituents in the meta position of the benzyl group, revealing a significant correlation between this behavior and functional potency at the rat 5-HT2A receptor.
Molecular modelling of human 5-hydroxytryptamine receptor (5-HT2A) and virtual screening studies towards the identification of agonist and antagonist molecules
TLDR
The ligand interaction study using the two prominent states of GPCR, namely the active and inactive state of the 5-HT2A receptor, confirmed that agonists and antagonists interact in different modes with the receptor.
Assessment of the Roles of Serines 5.43(239) and 5.46(242) for Binding and Potency of Agonist Ligands at the Human Serotonin 5-HT2A Receptor
TLDR
Using the ergoline lysergic acid diethylamide (LSD), and a series of substituted tryptamine and phenethylamine 5-HT2A receptor agonists, it is found that Ser5.43(239) is more critical for agonist binding and function than S5.46(242), which is consistent with the functional topography and utility of the in silico-activated homology model of the h5-HT 2A receptor.
Dibenzofuranylethylamines as 5-HT2A/2C Receptor Agonists
TLDR
Five phenethylamine analogs in which the benzene ring is replaced by a bulky dibenzo[b,d]furan moiety are synthesized and found a couple with >70-fold 5-HT2C selectivity.
Molecular interactions of agonist and inverse agonist ligands at serotonin 5-HT2C G protein-coupled receptors: computational ligand docking and molecular dynamics studies validated by experimental mutagenesis results
TLDR
The movement of TMs 5 and 6 upon agonist and inverse agonist ligand binding observed in the 5-HT2C receptor modelling studies was similar to movements reported for the activation and deactivation of the β2AR, suggesting common mechanisms among aminergic neurotransmitter GPCRs.
Similarities between the Binding Sites of SB-206553 at Serotonin Type 2 and Alpha7 Acetylcholine Nicotinic Receptors: Rationale for Its Polypharmacological Profile
TLDR
The analysis showed that the most plausible binding sites for SB-206553 at 5-HT2Rs and α7 nAChR are remarkably similar, both in size and chemical nature of the amino acid residues lining these pockets, thus providing a rationale to explain its affinity towards both receptor types.

Site-directed mutagenesis of the serotonin 5-hydroxytrypamine2 receptor: identification of amino acids necessary for ligand binding and receptor activation.
TLDR
Results indicate that Asp-120 is necessary for allosteric activation of the guanine nucleotide-binding protein in the 5-HT2 receptor, probably by acting as a counterion for the amine group of the ligand.
Differential modes of agonist binding to 5-hydroxytryptamine(2A) serotonin receptors revealed by mutation and molecular modeling of conserved residues in transmembrane region 5.
TLDR
The results suggest that relatively minor changes in either receptor or ligand structure can produce drastic and unpredictable changes in both binding interactions and 5-HT(2A) receptor activation.
Identification of conserved aromatic residues essential for agonist binding and second messenger production at 5-hydroxytryptamine2A receptors.
TLDR
It is demonstrated that highly conserved aromatic residues residing in neighboring helices provide the optimum environment for both agonist binding and activation of 5-HT2A receptors.
A single point mutation (Phe340-->Leu340) of a conserved phenylalanine abolishes 4-[125I]iodo-(2,5-dimethoxy)phenylisopropylamine and [3H]mesulergine but not [3H]ketanserin binding to 5-hydroxytryptamine2 receptors.
TLDR
The results are consistent with the idea that agonists and certain ergot derivatives anchor to 5-HT2 receptors, in part, via specific interactions with aromatic residue Phe340 located in transmembrane region VI.
Differential phospholipase C activation by phenylalkylamine serotonin 5‐HT2A receptor agonists
TLDR
The hypothesis that phenylisopropylamines have higher hallucinogenic potency than their phenethylamine analogues primarily because they have higher intrinsic activities at 5‐HT2A receptors is supported.
A homology-based model of the human 5-HT2A receptor derived from an in silico activated G-protein coupled receptor
TLDR
A homology-based model of the 5-HT2A receptor was produced utilizing an activated form of the bovine rhodopsin (Rh) crystal structure, and the final binding orientations were observed to be compatible with much of the data acquired through both diversified ligand design and site directed mutagenesis.
Influence of amine substituents on 5-HT2A versus 5-HT2C binding of phenylalkyl- and indolylalkylamines.
TLDR
N-(4-bromobenzyl) substitution results in compounds that bind at 5-HT2A receptors with high affinity and with > 100-fold selectivity, whereas parallel structural modification in the two series result in parallel shifts in 5- HT2C binding, these same modifications alter 5-ht2A binding in a less consistent manner.

TLDR
A systematic alanine-scanning mutagenesis study on residues Tyr381 to Val387 within the binding domain of the M(1) muscarinic ACh receptor found that the hydroxyl group and benzene ring of Tyr381 both participate in interactions with azanorbornane- and quinuclidine-based ligands and atropine analogs in the ground state as well as the activated state of the receptor.
